Best AI Writing Tools: 16 Tested Picks (Free & Paid, 2025)

Choosing an AI writing tool shouldn’t feel like a blindfolded dart throw. Between chatbots, SEO suites, editing assistants, and “all‑in‑one” platforms, it’s easy to burn time and budget on tools that sound impressive but don’t fit how you actually create content. Maybe you need long‑context drafts without hallucinations, brand‑safe copy at scale, Google‑aligned optimization, or just a fast way to polish emails and posts. Either way, the wrong tool means generic output, rework, and stalled rankings.

This guide fixes that with 16 tested picks (free and paid) for 2025. We ran hands‑on trials across real workflows—blogs, landing pages, product descriptions, email, social, outlines, and edits—then scored each tool for quality, factual reliability, SEO support, brand voice control, speed, collaboration, integrations, and total cost. For every pick you’ll get why it stands out, who it’s for, key features, pricing, and things to consider—plus clear use‑case recommendations (from fully automated SEO publishing to everyday writing, Google Workspace synergy, conversion copy, deep editing, ecommerce scales, and creative prose). Expect concise summaries, transparent caveats, and quick answers so you can pick with confidence. First up: the option built for fully automated SEO content and publishing.

1. RankYak — best for fully automated SEO content and publishing

If you’re comparing the best AI writing tools and you want “set it and ship it,” RankYak is the outlier: it automates the entire SEO pipeline. It discovers keywords, plans the calendar, writes long‑form articles, adds links and images, then publishes to your CMS—daily—so you keep shipping content without babysitting drafts.

Why it stands out

Unlike general AI writing software, RankYak is built for Google and AI chat visibility together. It marries smart keyword discovery, SERP‑aligned structure, internal linking, topic clusters, citations, and brand‑voice adaptation with one‑click publishing. It even layers backlink exchange to accelerate authority. The result: an opinionated, end‑to‑end workflow that aims to cut SEO busywork by up to 90% and ship more content that actually ranks.

Who it’s for

If you want outcomes (traffic, rankings) more than tinkering with prompts, this is for you. Teams that need consistent publishing across 1–N sites without adding headcount will get the most lift.

• SMBs and founders: Replace scattered tools and irregular content with a daily publishing cadence.
• Content marketers: Keep the calendar full while maintaining on‑page SEO fundamentals.
• Agencies: Manage multiple client sites with separate subscriptions and automated delivery.

Key features

You get opinionated automation plus controls where it matters—brand, topics, and integrations.

• Smart keyword discovery: Finds high‑potential terms for Google and AI chats from your site/niche.
• Automated content plan: Generates a daily roadmap that compounds topic clusters.
• Daily long‑form articles: Up to 5,000 words with featured images, citations, and internal links.
• Auto‑publish: Push directly to WordPress, Shopify, Webflow, Wix, WordPress.com; Zapier/Make, API/webhooks.
• SEO for Google + AI: Search intent, E‑E‑A‑T signals, competitor inputs, facts/citations, brand voice.
• Backlink exchange: Build quality links via a curated network to grow authority.
• Multilingual support: 40+ languages for global sites.
• GSC integration: Learn from live performance to refine topics and coverage.
• Multi‑site management: One account; each site has its own plan, keywords, and schedule.

Pricing

One plan with everything: $99/month. Includes a 3‑day free trial, cancel anytime. Agencies and affiliates have dedicated programs. Each site runs on its own subscription.

Things to consider

Automation doesn’t remove accountability—review outputs for brand and accuracy, especially on YMYL topics per Google’s helpful content guidance. Daily generation is capped at one article per site. The backlink exchange complements (not replaces) bespoke digital PR. If you want hands‑on drafting or creative prose experimentation, pair RankYak with a general writer.

2. ChatGPT — best all-around AI writer for everyday tasks

When people ask for the best AI writing tools for quick wins—drafting emails, briefs, hooks, headlines, FAQs, or polishing paragraphs—ChatGPT is still the default pick. Its chat-first workflow makes ideation, rewrites, and “can you make this clearer/shorter/warmer?” edits fast, and it’s flexible enough to handle outlines, meta descriptions, and social posts without a steep learning curve.

Why it stands out

ChatGPT’s strength is speed plus versatility. You can iterate in conversation, ask follow‑ups, and steer tone or structure on the fly. With access to the GPT‑4o family (and 4.1 where available), it produces higher‑quality long‑form drafts and tighter summaries than most general AI writing software—without forcing you into rigid templates.

Who it’s for

If you need a reliable everyday AI writer to unblock ideas, tighten copy, or create first drafts you can quickly edit, ChatGPT belongs in your stack.

• Founders and SMB teams: Fast drafts for emails, landing copy, and support macros.
• Content marketers: Outlines, angles, and first passes for blogs and socials.
• Editors and PMs: Summaries, meeting notes, and “explain like I’m five” clarifications.

Key features

You’re not buying a rigid content generator—you’re getting a flexible co‑writer that adapts to each task.

• Conversational drafting and rewrites: Iterate tone, length, and style in‑chat.
• Structured outputs: Ask for outlines, tables, bullets, FAQs, and step lists.
• Custom GPTs and Projects: Package prompts/workflows and organize assets.
• Advanced Voice Mode and DALL·E: Speak to write; create accompanying images.
• File uploads and analysis: Summarize PDFs, extract bullets, or propose edits.
• Multilingual support: Draft or translate for international audiences.

Pricing

• Free tier: Core chat and drafting.
• Plus: Typically $20/month for priority access to advanced models/features.
• Pro: A higher‑tier plan (not required for most users). Availability and feature sets can change by region and time.

Things to consider

ChatGPT is an excellent general AI writing tool, but it’s not a turnkey SEO suite. Fact‑check names, stats, and claims—especially on YMYL topics—and expect to add internal links, citations, and schema elsewhere. Brand‑voice consistency improves with examples and guardrails, yet you’ll still want human review before publishing.

3. Gemini Advanced — best for Google Workspace and real-time web info

If your team lives in Docs, Gmail, and Drive, Gemini Advanced feels like a native upgrade to everyday work. It’s one of the best AI writing tools when you need quick drafts inside Google editors plus current, sourced information from the live web—great for briefs, outlines, and fact-checked summaries you can drop straight into your workflow.

Why it stands out

Gemini combines Google-aligned guidance with Workspace integration and real-time web results, so you can ideate, draft, and verify without tab-hopping. Its Deep Research capability (paid) helps synthesize sources, while Gemini’s free tier lets you test the core chat experience before rolling out to the team.

Who it’s for

You’ll get the most value if content moves through Google tools and your outputs benefit from fresh, linked sources.

• Workspace-first teams: Draft in Docs, refine emails in Gmail, and pull insights without leaving Google.
• Content and SEO managers: Create SERP-aware outlines and source-backed briefs quickly.
• Ops, sales, and CS: Summarize docs, generate responses, and repurpose updates across Slides and Sheets.

Key features

Gemini isn’t a rigid template machine; it’s a Google-native assistant that accelerates research and drafting where you already work.

• Workspace integration: Generate, rewrite, and summarize directly in Google editors.
• Real-time web info: Pull current context and references from across the web.
• Deep Research mode (paid): Structured synthesis of multi-source topics.
• Google-aligned guidance: Helpful for producing search-consistent, people-first content.
• Reusable prompts: Keep consistent instructions for tone and structure.
• Drive synergy: Store and organize outputs alongside your team’s files.

Pricing

There’s a free version for core chat and drafting. Paid tiers expand capability and integrate tightly with Workspace.

• Free: Chat-style drafting and rewrites.
• Google AI Pro (Gemini Advanced): Typically around $19.99/month; includes enhanced features and, per Google’s offer, 2 TB of Drive storage.
• Google AI Ultra: A higher-end plan (listed at $249.99) for advanced needs. Availability and inclusions can vary; check your account for current details.

Things to consider

Gemini’s strength is Workspace synergy and up-to-date sourcing, not long-form creative prose—pair it with Claude or ChatGPT if you prioritize narrative voice. As with all AI writing software, fact-check YMYL topics and add your own citations/attributions. It’s not a full SEO suite; for briefs, audits, and optimization, complement Gemini with a dedicated SEO tool or an automated platform like RankYak.

4. Claude — best for natural prose and long-context writing

If “sounds like a human” is your top criteria when comparing the best AI writing tools, Claude earns its spot. It excels at voice, rhythm, and nuance, and its huge context window lets you load book‑length material and keep continuity over long drafts. That combination makes it a favorite for authors and teams polishing narrative‑heavy content.

Why it stands out

Claude is praised for exceptionally natural prose and for handling very large inputs without losing the thread. With a massive context window (up to around 200K tokens, enough to ingest ~150,000 words), it can read, summarize, and continue long documents coherently. Projects, editable styles, and Google Drive integration help you keep tone consistent while moving fast across big bodies of work.

Who it’s for

If your workflow leans on tone, continuity, and long documents, Claude is an easy win.

• Authors and creatives: Draft or revise scenes and chapters with lifelike cadence.
• Content leads and editors: Improve long articles, reports, and scripts without fragmenting context.
• Marketing and comms: Produce on‑brand emails and social copy that doesn’t feel robotic.
• Knowledge teams: Ingest and summarize lengthy PDFs, then generate clear, human‑readable outputs.

Key features

Claude is a voice‑first AI writing software option designed to keep context and style intact.

• Massive context window: Work with book‑length inputs (≈200K tokens; ~150K words).
• Natural prose generation: Strong, human‑sounding drafting and rewrites.
• Projects workspace: Organize topics and assets for ongoing work.
• Styles you can edit: Create and tweak voice presets for consistency.
• Google Drive integration: Pull and save files without breaking flow.

Pricing

• Claude Pro: From $17/month when billed annually (per Kindlepreneur’s testing). Feature availability can vary by region and plan.

Things to consider

Claude favors quality prose over gadgetry. That’s a plus for writing—just know the edges.

• Safety filters: It’s “highly censored,” which can block NSFW or graphic content.
• Fewer extras than some rivals: Lacks several features others offer (e.g., deep research modes, voice or image generation).
• Not an SEO suite: Use a dedicated optimizer or automated platform for briefs, internal links, and technical checks.
• Editorial diligence still matters: Fact‑check YMYL topics and cite sources to align with Google’s helpful content guidelines.

5. Jasper — best for brand voice and enterprise content teams

If you’re scaling content across multiple stakeholders, Jasper stands out among the best AI writing tools for keeping tone, terminology, and formats consistent. With 100,000+ users (including brands like AirBnB, Intel, Zoom, and Verizon), it pairs high‑quality generation with brand voice learning, collaboration, and assets you can reuse across teams.

Why it stands out

Jasper’s Brand Voice (formerly Boss Mode) ingests your existing content to mirror tone, style, and depth—critical when multiple writers contribute to one brand. On top of strong drafting, you get templates, permissions, and creation tools that help large teams move faster without sacrificing consistency, plus Jasper Art for images when you need supporting visuals.

Who it’s for

If you manage brand‑sensitive content at scale, Jasper is a pragmatic pick.

• Marketing and content teams: Produce blog posts, ads, emails, and landing copy with a consistent voice.
• Enterprises and agencies: Standardize outputs across seats, clients, and regions.
• Global teams: Draft in multiple languages while maintaining brand tone.

Key features

Beyond being an AI writer, Jasper adds brand governance and collaboration so teams can produce reliably on‑brand content.

• Brand Voice training: Learn tone and style from your existing assets for consistent outputs.
• 50+ templates: Blogs, product descriptions, ads, emails, social posts, and more to speed up briefs and drafts.
• Multilingual support: Generate in 25 languages for international campaigns.
• Collaboration and workflows: Automation and team tools to accelerate production at scale.
• Jasper Art: Create on‑brand images from text prompts to complement copy.
• Chat assistant: Bounce ideas, outline, and refine in a conversational flow.
• API and Chrome extension: Use Jasper inside your browser and connect to other software.

Pricing

Clear plans that fit solo creators through teams.

• Creator (single seat): Starts at $39/month.
• Teams (3 seats): $99/month.
• Trial: 7‑day free trial available; payment details required to access.

Things to consider

Jasper isn’t a full SEO suite, so you’ll still want dedicated optimization or an automated SEO platform for briefs, internal links, and audits. Expect a short learning curve to get the most from Brand Voice and templates. As with all AI writing software, fact‑check claims and add citations on YMYL topics to align with Google’s helpful content guidelines; Jasper’s own chat feature can occasionally format oddly and long‑form drafts still benefit from human editing to nail search intent and nuance.

6. Copy.ai — best for go-to-market workflows and marketing copy

If your team ships campaigns across email, social, ads, and blog in tight cycles, Copy.ai is a strong pick among the best AI writing tools. It combines a simple chat-style writer with prebuilt workflows for SEO blog briefs, repurposing, and go‑to‑market tasks—so marketing, sales, and ops can move from idea to launch fast without building complex prompt systems.

Why it stands out

Copy.ai balances speed and structure. You can stay in a conversational flow or snap into templates and workflows that scrape SERPs for talking points, assemble outlines, and draft posts. It also now markets itself as a go‑to‑market platform, layering prospecting, sales, and CRM workflows alongside its core copy tools.

Who it’s for

• Growth and GTM teams: Coordinate blog, email, and social assets from one place.
• Solo marketers/SMBs: Generate usable first drafts quickly, then refine.
• Agencies: Standardize briefs and outputs across multiple clients.

Key features

• Chat interface + 45 templates: Blog posts, emails, social captions, website copy, and more.
• SEO blog workflow: Builds outlines and drafts from target keywords and competing SERPs.
• Brand voice mimic: Paste examples to match tone across assets.
• Multilingual support: Draft in 25+ languages for global campaigns.
• Workflows for GTM: Prospecting, sales, and CRM-style automations to support pipeline content.

Pricing

• Free plan: 2,000 words/month to trial the platform.
• Paid plan: Starts at $49/month and includes 5 users with unlimited words and projects (good value for small teams).

Things to consider

Outputs can skew generic if you don’t add unique insights, data, or POV—expect editing to align with brand and search intent. The SEO workflow speeds up briefs and drafts but isn’t a full optimizer; pair with a dedicated SEO check or an automated publishing platform for internal links, citations, and on‑page structure. As with any AI writing software, fact‑check YMYL topics before publishing.

7. Writesonic — best for fast blog posts and ad/social copy

Writesonic is a speed play among the best AI writing tools. It’s built to spin up usable drafts in minutes with 100+ templates, a simple 4‑step workflow, and a Brand Voice option to keep tone on target. You can point it at ranking examples (or paste sources), then generate SEO‑ready, plagiarism‑checked copy for blogs, ads, product pages, and social without wrestling complex prompts.

Why it stands out

For busy marketers, the combination of an approachable UI, broad template coverage, and quick “pick references → generate” flow makes Writesonic ideal for fast campaigns. Add‑ons like an image generator and chatbot assistant extend it beyond a plain text tool, so you can assemble lightweight, ready‑to‑publish assets in one place.

Who it’s for

If you ship frequent ad/social iterations and need quick blog drafts you can tighten later, Writesonic fits. It’s a strong choice for SMBs, ecommerce teams producing product descriptions at pace, and solo marketers who want straightforward controls over advanced tinkering.

Key features

• 100+ templates: Blogs, landing pages, product descriptions, ads, and social captions.
• Source‑guided drafting: Search topics, pick top‑ranking examples, paste links, or upload files before generating.
• Brand Voice: Capture style from your existing content to keep outputs consistent.
• SEO + plagiarism checks: Generates SEO‑optimized copy and runs built‑in plagiarism screening; an SEO checker can be run after drafting.
• Editing helpers: Title generator, paraphraser, expander, and summarizer for fast cleanups.
• Chatbot tools: A chatbot assistant and simple bot builder for conversational use cases.
• Image generator: Create visuals to pair with copy in the same workflow.

Pricing

Writesonic’s entry pricing is accessible: plans start around $12.67/month for 1 user and up to 200K words on GPT‑3.5 (or roughly 33K words on GPT‑4 at the same price). An “Unlimited” plan is listed from about $16/month, and there’s a free plan with 10,000 words to test it out. Pricing and word allocations can change—check plan details before committing.

Things to consider

• Credit/word math: Word/credit accounting can feel opaque; monitor usage.
• SEO pass needed: The SEO checker runs separately; expect tweaks to hit stronger scores.
• Long‑form polish: Longer articles often need editorial work to meet search intent and add depth.
• Generic risk: Like most AI writing software, outputs improve when you add unique insights, data, and examples—fact‑check before publishing.

8. Rytr — best budget AI writer with multilingual support

Rytr is a popular, low-cost pick when you want quick, decent copy without a steep learning curve. With 40+ use cases and support for 30+ languages, it covers everyday needs—blogs, emails, product descriptions, ads—making it an easy add to your toolkit of best AI writing tools.

Why it stands out

Rytr combines breadth and price. It offers ready-made templates, 20+ tones, a plagiarism check, and even image generation—all at an entry point that undercuts most AI writing software. You can also build custom use cases to match recurring tasks.

Who it’s for

Budget‑conscious marketers, solo creators, and SMBs who need fast drafts across multiple languages without complex setup.

• Freelancers shipping short‑form copy quickly
• Ecommerce owners writing product pages and emails

Key features

You get lightweight generation plus helpful helpers for cleanup and ideas.

• 40+ templates (blogs, emails, product descriptions, ads, web copy)
• 30+ languages and 20+ tones for on‑brand outputs
• Plagiarism checker and image generation built in
• SEO helpers (keyword extractor/generator) and rewrite/expand tools

Pricing

Starts at about $9/month for 100k characters, with a free plan offering 10k characters/month. Character-based quotas keep costs low but require a bit of math on output.

Things to consider

Rytr shines on short‑form tasks; long‑form articles often need more editing and SEO depth. Quotas are measured in characters (not words), which can feel opaque. As with any AI writing tool, add facts, examples, and citations—especially for YMYL topics—to meet Google’s helpful content expectations.

9. Grammarly — best free editor with AI writing assist

Grammarly is the “always‑on” editor that levels up anything you type, which is why 30M+ people use it daily. Among the best AI writing tools for everyday quality control, it flags correctness, clarity, engagement, and delivery in real time—and with GrammarlyGO, it can also draft, rephrase, and shorten on command without leaving your app.

Why it stands out

Grammarly’s superpower is ubiquity plus instant feedback. Whether you’re in Chrome, Windows, iOS, or Android, you get inline fixes and a live score so you can ship polished copy fast. Turn on GrammarlyGO when you need quick co‑writing—subject lines, replies, outlines, or “make this clearer” rewrites—directly where you’re working.

Who it’s for

If you write across many apps and want a low‑friction safety net, Grammarly fits. It’s ideal for busy teams that need consistent baseline quality, founders polishing emails and landing copy, and editors who want fast readability upgrades before deep line edits.

Key features

You get real‑time editing plus lightweight AI writing assist to speed up common tasks.

• Inline suggestions + score: Dashboards for Correctness, Clarity, Engagement, Delivery.
• Everywhere you write: Plug‑ins for Windows, Chrome, iOS, and Android; web app for paste‑in checks.
• GrammarlyGO co‑writer: Rephrase, shorten, simplify, adjust tone, and generate ideas/snippets.
• Email reply generator: Draft responses from context in a click.
• Style nudges: Consistency, fluency, and readability improvements beyond typos.

Pricing

Grammarly is free for basic correctness/clarity and includes 100 GrammarlyGO prompts/month. Premium is listed at about $12/month, unlocking deeper checks (consistency, engagement, fluency) and 1,000 GrammarlyGO prompts/month. Plans and inclusions can vary by region—confirm in‑app before upgrading.

Things to consider

Grammarly writes and edits only in English. It’s not an SEO optimizer, so you’ll still need briefs, internal links, citations, and schema elsewhere. Treat GrammarlyGO as assistive—fact‑check names, stats, and YMYL claims to align with Google’s helpful content guidance before publishing.

10. ProWritingAid — best for in-depth editing and style reports

If your drafts are “good” but not publication‑ready, ProWritingAid is the editor that finds what simple spellcheckers miss. It’s built for professional polish with 20+ granular reports that surface repetition, jargon, clichés, and readability issues—making it one of the best AI writing tools for serious line editing and revision.

Why it stands out

Depth and coaching. Beyond catching grammar and spelling, ProWritingAid analyzes style and clarity at a professional level, then explains the “why” behind each suggestion. You can tailor feedback for creative, professional, or academic writing, and it’s notably helpful for non‑native English writers thanks to clear explanations of edits.

Who it’s for

If you want actionable diagnostics rather than generic rephrasing, this tool fits. It’s a strong add‑on to any AI writing software stack when quality control matters.

• Authors and journalists: Line edits that improve pacing, clarity, and voice.
• Academics and researchers: Style guidance without losing precision.
• Copywriters and marketers: Consistent, on‑brand readability across assets.
• ESL writers: Explanatory suggestions to build confidence and fluency.

Key features

Start with a clean pass, then open focused reports to tackle higher‑order issues without guesswork.

• 20+ improvement reports: Style, repetition, clichés, and unexplained jargon.
• Real‑time fixes: Grammar, spelling, and style nudges as you write.
• Mode‑specific guidance: Creative vs. professional/academic feedback.
• ESL‑friendly explanations: Learn the rationale behind changes.
• Flexible access: Browser (Chrome), Windows app, and web editor.

Pricing

You can try core checks on a tight cap, then upgrade when you need full reports. Plans are straightforward.

• Free plan: Check up to 500 words/day.
• Premium: Starts at $20/month or $80/year (discounted annual).
• Lifetime license: $399 one‑time.

Things to consider

ProWritingAid is an editor, not a text generator—pair it with a writer like ChatGPT or Claude. It doesn’t handle SEO tasks (briefs, internal links, schema), so you’ll still need an optimizer or a platform like RankYak for search‑ready drafts. And while the free cap is useful for testing, longer documents quickly require Premium.

11. QuillBot — best for paraphrasing, summarizing, and citations

QuillBot is the utility knife in a stack of the best AI writing tools: a fast way to rephrase, tighten, summarize, translate, and cite without opening five tabs. Instead of forcing full drafts, it focuses on high‑control rewrites and research helpers that slot into your existing workflow.

Why it stands out

Targeted paraphrasing modes give you granular control—keep meaning, improve fluency, simplify, formalize, expand, or shorten—so you can quickly refit copy for different audiences or channels. Pair that with a solid summarizer and a built‑in citation generator, and you’ve got a go‑to for academic, editorial, and blog cleanup. A no‑signup free tier and handy Chrome/Word/Mac integrations make it easy to adopt.

Who it’s for

• Students and researchers who need fast summaries and properly formatted citations.
• Editors, bloggers, and marketers repurposing or tightening existing text.
• Non‑native English writers seeking clarity and fluency improvements.
• Multilingual teams that need quick paraphrases across languages.

Key features

• Paraphraser modes: Standard, Fluency, Formal, Simple, Creative, Expand, Shorten.
• Summarizer and grammar checker: Condense and clean up long passages.
• Plagiarism checker + citation generator: Reduce duplication risk and cite sources correctly.
• Translator: Work across languages (supports 23).
• Co‑Writer: Word‑processor environment with paraphrase/summarize and research + citation tools.
• Integrations: Web app plus extensions for Chrome, Microsoft Word, and macOS.

Pricing

• Free: No signup required for some features; paraphrase up to 125 words at a time in Standard and Fluency modes.
• Premium: Starts at about $6.25/month; unlocks unlimited paraphrasing and additional tools/modes.

Things to consider

QuillBot doesn’t differentiate between US and British English, which can matter for style guides. It’s an assistive editor—not a long‑form generator—so pair it with a writer if you need original drafts. As always, fact‑check YMYL content and use citations to align with Google’s helpful content guidelines.

12. Surfer — best for SEO optimization and content briefs

When you’re comparing the best AI writing tools for search performance, Surfer stands out as the optimizer you use before you hit publish. Its content editor reverse‑engineers the top SERP results and gives you a clear, points‑based checklist—so writers know exactly what to include and editors can quantify “done.”

Why it stands out

Surfer translates competitor and keyword analysis into a practical brief with targets for headings, keywords, images, word count, and paragraph structure. The live content score keeps everyone aligned on what it will take to compete, and native integrations make it easy to work where your team already writes.

Who it’s for

If your bottleneck is “what will make this rank?” rather than “how do we draft faster?”, Surfer is a fit. Content teams, editors, and agencies use it to turn SERP data into actionable outlines and on‑page optimization that writers can follow.

• Content managers: Standardize briefs and raise baseline SEO quality.
• Editors and writers: Optimize as you draft with a live score.
• Agencies: Deliver measurable on‑page improvements across clients.

Key features

You get a guided, SERP‑driven workflow that bridges research and writing without overcomplicating the process.

• Content Editor with score: Checklist of keywords, headings, images, word count, and paragraph targets.
• Competitor analysis: Analyzes top‑ranking pages to set clear on‑page benchmarks.
• Keyword research: AI‑assisted discovery to shape briefs and clusters.
• Add‑ons: AI content generator and audit tool (available as paid add‑ons).
• Integrations: Google Docs, WordPress, Semrush, Jasper, plus an API for custom workflows.

Pricing

Surfer starts at about $69/month when billed annually. That tier includes 2 seats and roughly 180 keyword analyses. The AI generator and audit tool are paid add‑ons. There’s no free plan, but you can try a free AI outline generator and a free Google keyword extension.

Things to consider

Surfer is an optimizer, not a full content factory—expect to pair it with a writer for drafting and with publishing workflows for scale. It’s powerful and user‑friendly but on the pricier side once you add extras. As always, verify facts and add citations, especially for YMYL topics, to align with Google’s helpful content guidance.

13. Frase — best for research, outlines, and SERP-driven drafts

Frase is a user-friendly blend of SEO research and AI drafting that helps you move from keyword to outline to first draft fast. If you want an assistant that studies top SERPs, proposes a structure, and then generates long‑form copy against that plan, it deserves a spot on any short list of the best AI writing tools.

Why it stands out

Frase turns competitive analysis into a practical workflow. You feed it a topic, it scrapes high‑ranking pages, surfaces what they cover, and converts that into an outline you can expand with its long‑form writer. It also goes beyond simple NLP keyword stuffing, pulling contextual signals for more “human” outputs.

• Research → brief → draft in one place
• Clean, simple interface that’s easy to learn
• High-quality long‑form generation aligned to SERP findings

Who it’s for

Frase fits teams that want SERP‑aware drafts without mastering complex SEO tools or prompt engineering.

• Content marketers and editors needing fast briefs and first drafts
• SMBs and solo creators who want guidance on “what to cover” before writing

Key features

Frase focuses on speeding up the parts of writing that slow most teams down: research and structure.

• SERP scraping and analysis of top competitors
• Suggested keywords, headings, and content coverage
• Long‑form AI Writer that expands your SEO‑informed outline
• Streamlined editor to refine and optimize within the same UI

Pricing

Frase pricing starts around $12.66/month for 4 SEO articles. Flexible options include Unlimited AI generation (without SEO tools) at ~$35/month and ~30 optimized articles at ~$38.25/month. There’s a trial (typically $1 for 5 days); payment details are required.

Things to consider

• Trial isn’t free; minimal fee and card required
• Outputs still benefit from human editing to sharpen search intent
• Not a full technical SEO suite—use alongside audits and on‑page checks
• As with any AI writing software, fact‑check and cite sources on YMYL topics

14. Anyword — best for conversion-focused copy with predictability scores

If your north star is clicks and conversions, Anyword earns a spot among the best AI writing tools by showing you how copy is likely to perform before you ship it. Instead of guessing, you get data-backed scores and suggestions that help headlines, ads, and emails land with the right audience.

Why it stands out

Anyword blends large language models with performance prediction. You write or paste copy, pick your audience persona, and get a score with specific improvement tips. An editor with 100+ templates keeps work moving, and brand voice plus audience targets help standardize outputs. Its Talking Points feature even suggests high-impact messages for HubSpot Email and Google Ads campaigns.

• Outcome-first editing: Optimize existing copy for engagement and conversion, not just grammar.
• Predictive scoring: See likely performance by audience segment before you launch.

Who it’s for

Performance-minded teams that live on measurable results.

• Paid media and social teams: Stronger headlines, hooks, and variants for ads.
• Email marketers and lifecycle teams: Subject lines and body copy tuned to lift CTR and replies.
• CRO and content leads: Test angles and tighten messaging across pages and campaigns.

Key features

Anyword focuses on conversion lift, giving marketers a practical, repeatable workflow.

• Predictive performance scores by audience persona
• 100+ templates across ads, email, social, website copy
• Brand voice + target audiences to keep tone consistent
• Talking Points suggestions for HubSpot Email and Google Ads
• A/B testing workflows to compare variations
• Works with ChatGPT, Notion, and HubSpot to fit existing stacks

Pricing

Pricing starts at $39/month for 1 user with no limits on how many words or articles you can check or edit, plus a 7‑day free trial. Access to all features may require higher tiers; confirm current plan details in‑app.

Things to consider

Anyword prioritizes optimization over long‑form generation; think “make it convert,” not “write a 2,000‑word post.” Some teams may find advanced feature tiers pricey. As with any AI writing software, add unique insights, and fact‑check YMYL claims to align with Google’s helpful content guidelines and your brand standards.

15. Hypotenuse — best for ecommerce product descriptions at scale

If you sell online and need hundreds of on‑brand, SEO‑ready product blurbs, Hypotenuse belongs on your shortlist of the best AI writing tools. It’s built to turn catalog data into consistent, conversion‑focused copy—and to do it in bulk without babysitting prompts.

Why it stands out

Hypotenuse pairs a direct Shopify integration (or an API for other platforms) with a batch generator that can spin up product titles, summaries, and descriptions at scale. Beyond catalog copy, it also handles short‑form marketing like Google/Facebook ads and Instagram captions, so you can ship listings and promo assets in one pass.

Who it’s for

Merchants, marketplaces, and ecommerce agencies that need fast, uniform product content across large catalogs—and want lightweight ad/caption support without juggling extra tools.

• Ecommerce integration: Direct Shopify connection or use the API to plug into other storefronts.
• Ad/social templates: Generate Google/Facebook ads and Instagram captions from the same inputs.
• Meta fields: Create meta titles and descriptions alongside product copy.
• Paraphrase, summarize, simplify: Clean up or rework existing listings and briefs.

Pricing

Plans start around $15/month for 20,000 words, with a 7‑day free trial to test throughput and quality. Confirm current tiers in‑app before scaling.

Things to consider

Hypotenuse focuses on short‑form ecommerce and promo copy; it offers fewer templates than some rivals and isn’t a deep SEO suite. For maximum results, add unique attributes, facts, and brand rules to inputs, then spot‑check outputs for accuracy—especially specs—and align with your store’s tone and search strategy. Pair with an optimizer or automated SEO platform when you need briefs, internal linking, and technical checks at scale.

16. Sudowrite — best for fiction and creative writing

When you’re comparing the best AI writing tools for story craft, Sudowrite is the one built for scenes, characters, and voice. Instead of churning out bland blog posts, this AI writer helps you brainstorm, draft, and revise fiction with tools that nudge momentum and preserve style.

Why it stands out

Sudowrite focuses on creative flow from idea to revision. Its prose‑tuned model produces natural‑sounding narrative, and the step‑by‑step workspace keeps you moving—brainstorm, outline, draft the next beat, then refine with descriptive detail or line edits. You get coaching without losing your voice, which is rare in general AI writing software.

Who it’s for

If you’re an author or hobbyist who wants help brainstorming and drafting chapters without wrestling SEO templates, Sudowrite fits. It’s equally useful for novelists, short‑story writers, and anyone shaping narrative‑heavy work who values continuity and cadence over marketing checklists.

Key features

Sudowrite gives you creation tools built for fiction rather than generic content.

• Brainstorm + Canvas: Generate characters, settings, and plots, then organize them.
• Write tool: Overcome blocks with the next ~300 words generated in‑context.
• Rewrite/expand: Recast or extend passages while preserving tone.
• In‑line thesaurus: Swap words without breaking flow.
• Describe (sensory detail): Add texture using chosen senses.
• Visualize: Create images of a scene for inspiration.
• Feedback: Actionable notes with three areas for improvement; rerun as needed.
• No templates, 9‑step flow: A process designed around the creative writing lifecycle.

Pricing

Pricing starts at about $10/month for 30,000 words. There’s no free plan, but you can try a 3‑day free trial to test the workflow.

Things to consider

Sudowrite is purpose‑built for prose, not SEO or business copy. It’s less flexible than general tools and the trial is short, so plan focused testing. For publishing or optimization needs, pair it with an SEO tool or an automated platform and use Sudowrite where it shines—voice, scenes, and revision.
