Best AI Writing Tools

Our picks, explained

1. 01

   Claude

   For long-form writing

   Claude is the assistant we reach for when the piece is long, the brief is detailed and the tone matters. It reads a lot of material and writes back in a measured, natural voice.

   Why consider it?

   Claude follows tone and style instructions closely, and its context window goes up to 1M tokens. That means you can paste in a full report, a stack of interview notes or an old draft and ask for a rewrite that keeps your facts. Projects let you save a style guide and sources so every new chat starts from the same brief, and Artifacts give you a side panel for the document you are working on.

   The free plan has limits and Pro starts from $17 a month, so heavy writing days can hit the cap. Claude still invents details now and then, so check every figure and quote before it goes out. If you are weighing it against its biggest rival, our ChatGPT vs Claude comparison covers the differences.

   Strengths

   • Natural, careful style that follows tone instructions
   • Handles very long documents and source material
   • Projects keep your style guide and sources in one place

   Considerations

   • Free and Pro plans have usage limits on heavy days
   • Can state wrong facts with confidence
   • Fewer all-in-one extras than ChatGPT

   ChatGPT

   For all-round help

   ChatGPT is the one tool that can plan an article, draft it, make an image for it and then check the numbers. If you only want to pay for one assistant, this is the safest default.

   Why consider it?

   ChatGPT covers drafting, brainstorming, research and data analysis in one place, and adds image generation and voice on top. Deep research is useful when you need a sourced overview before you write, and uploading a spreadsheet or PDF lets you ask questions about it directly. Custom instructions and custom GPTs save your preferences, so repeat jobs like newsletter intros or product descriptions start in your tone instead of from scratch.

   Left alone, its writing leans generic and a little upbeat, so give it examples of your voice and cut the filler. Limits on the free plan are tight and change often, and Plus is $20 a month. Like every chatbot it can be confidently wrong, so verify anything you plan to publish.

   Strengths

   • Most versatile assistant, from drafts to data analysis
   • Image generation, voice and deep research included
   • Custom instructions save your tone and preferences

   Considerations

   • Default tone is generic without guidance
   • Limits differ by plan and change often
   • Needs fact-checking like every chatbot

   Grammarly

   For editing and polish

   Grammarly does not write your article for you, and that is the point. It sits inside your browser, your email and your documents and tidies what you have already written.

   Why consider it?

   It checks grammar, clarity and tone as you type, and it works across apps, so the same suggestions follow you from a Google Doc to a LinkedIn post to an email. The free plan includes 100 AI prompts a month, and Pro costs $144 a year, which works out to $12 a month. For most people the free checker already catches the embarrassing errors, and the paid plan unlocks more of the AI features once you outgrow it.

   It is an editor, not a drafting partner, so pair it with Claude or ChatGPT for the first draft and use Grammarly for the final pass. Its suggestions can also flatten a distinctive voice if you accept everything, so read each change before you click. Writers who work on very long manuscripts may prefer a deeper editor, which we cover further down the list.

   Strengths

   • Works in the browsers and apps you already use
   • Instant grammar, clarity and tone suggestions
   • Free plan with 100 AI prompts a month

   Considerations

   • Edits text rather than drafting it
   • Accepting every suggestion can flatten your voice
   • Pro is billed yearly at $144

   Jasper

   For marketing teams

   Jasper is built for marketing teams that need consistent copy across many people and channels. It is the most business-like tool on this list, and it is priced that way.

   Why consider it?

   The core feature is brand voice: you teach Jasper how your company writes, and it applies that voice to blog posts, emails, ads and social posts. Campaign workflows and team collaboration features then keep several writers working from the same brief. That structure is what you pay for, since a solo writer can get most of the raw drafting from Claude or ChatGPT for much less money.

   Pro costs $59 per seat a month billed yearly, or $69 month to month, and there is a 7-day free trial but no permanent free plan. If your job is ad copy specifically, see our guide to the best AI tools for ad copy, where Jasper is compared with Anyword and others. For a team that ships a lot of branded content, the consistency can be worth the price.

   Strengths

   • Brand voice keeps copy consistent across a team
   • Campaign workflows for blogs, emails, ads and social
   • Built for collaboration, with seats and shared briefs

   Considerations

   • Expensive for solo writers at $59 per seat
   • No permanent free plan, only a 7-day trial
   • General assistants can do much of the raw drafting

5. 05

   Sudowrite

   For fiction writers

   Sudowrite is the odd one out here, and the most interesting. Instead of serving every kind of writer, it is built for people writing stories, from short fiction to full novels.

   Why consider it?

   It helps with the parts of fiction that a general chatbot handles clumsily: brainstorming, drafting scenes and rewriting a passage in a different style. The Professional plan adds a Feedback tool, and every plan runs on a monthly pool of credits rather than unlimited use, so long drafting sessions burn through them. Hobby and Student gives 225,000 credits a month, Professional gives 1,000,000 and Max gives 2,000,000, with unused Max credits rolling over for 12 months.

   There is no free plan, only a free trial that needs no card. Hobby and Student costs $19 a month, or $10 a month billed yearly, and Professional is $29 a month, or $22 billed yearly. Whether AI belongs in your fiction at all is a personal call, so use it as a sparring partner rather than a ghostwriter.

   Strengths

   • Built specifically for fiction rather than general text
   • Feedback tool on the Professional plan
   • Free trial with no card and low-priced student pricing

   Considerations

   • No permanent free plan
   • Credits run out faster in long drafting sessions
   • Narrow focus, so poor value for business writing

6. 06

   Writesonic

   For AI search visibility

   Writesonic began as an article generator and now leans into AI search visibility, which changes who it suits.

   Why consider it?

   It tracks how your brand appears in ChatGPT, Gemini and Google AI Overviews, then pairs that with an AI article writer and site audits. That suits SEO and content teams more than someone who just wants a quick draft. Starter is $79 a month billed yearly, with a free trial and no card needed. For classic keyword work, see our best AI tools for SEO.

   Strengths

   • Tracks brand mentions in AI search answers
   • AI article writer and site audits in one platform

   Considerations

   • Starter at $79 a month is steep for casual use
   • More of a marketing platform than a writing assistant

7. 07

   Copy.ai

   For repeatable marketing workflows

   Copy.ai has moved from a simple copy generator to a workflow platform for go-to-market teams.

   Why consider it?

   Its Chat plan gives unlimited words across models from OpenAI, Anthropic and Google Gemini, so you can switch models for different jobs without juggling subscriptions. Higher plans add workflow credits for automating repeatable marketing tasks. Chat costs $29 a month, or $24 a month billed yearly. We could not confirm a permanent free plan, so check the current plans before you commit.

   Strengths

   • Unlimited words in chat across several models
   • Workflows automate repeat marketing tasks

   Considerations

   • Free plan unconfirmed, so check before relying on it
   • Aimed at go-to-market teams more than solo writers

8. 08

   ProWritingAid

   For book editing and style reports

   ProWritingAid is the editor for people who care about how a long manuscript reads, not just whether the commas are right.

   Why consider it?

   It is best known for detailed style and grammar reports that you review across a whole chapter or article, which suits novelists, bloggers and anyone polishing long-form text. Pricing is unusual: Premium is $30 a month, $120 a year or $399 for a lifetime license, and Premium Pro is $36 a month, $144 a year or $699 lifetime. All plans carry a three-day money-back guarantee, although monthly plans are not refundable.

   Strengths

   • Deep reports across a whole manuscript
   • Lifetime license instead of a subscription

   Considerations

   • Month-to-month billing is steep at $30
   • Lifetime plans cost $399 to $699 up front

   QuillBot

   For paraphrasing and summaries

   QuillBot is the tool students and researchers open when a sentence needs rewording or a long source needs shrinking.

   Why consider it?

   The paraphraser offers tone modes, and the same app includes a summarizer and a citation generator, so it covers several study-desk jobs in one tab. The free plan works with limits. Premium is $99.95 a year, $39.95 a quarter or $19.95 a month. Use it to improve your own sentences and cite your sources properly, because rewording someone else's idea without credit is still plagiarism. Our best AI tools for students guide has more options.

   Strengths

   • Paraphraser, summarizer and citation generator in one app
   • Free plan with limits

   Considerations

   • Paraphrasing does not replace citing sources
   • Best price needs a yearly Premium plan

    Wordtune

    For rewriting your own sentences

    Wordtune is a small, focused rewriter: highlight a sentence and it offers alternatives in a different tone or length.

    Why consider it?

    The free Basic plan gives unlimited spelling and grammar corrections, 10 daily rewrites and 3 monthly AI summaries. Advanced costs $6.99 a month billed yearly, or $13.99 monthly, with 30 daily rewrites and 15 monthly summaries. Unlimited is $9.99 a month billed yearly, or $19.99 monthly, with no usage limits. Both paid plans start with a 3-day free trial, which is enough to test whether the rewrites suit your style.

    Strengths

    • Genuinely free Basic plan with daily rewrites
    • Low-priced paid plans from $6.99 a month billed yearly

    Considerations

    • Daily caps on rewrites below the Unlimited plan
    • Does not draft long pieces from scratch

    Notion AI

    For writing inside your docs

    If your notes, project plans and drafts already live in Notion, its AI saves the copy-and-paste trip to another app.

    Why consider it?

    Notion AI offers workspace Q&A, summaries and meeting notes directly in your pages, which makes it a good way to turn rough notes into a clean document. Full Notion AI comes with the Business plan, from $20 per member a month billed yearly, and students on the free Education plan get limited AI trials. Because it only works inside Notion, it makes sense mainly if you already use it every day.

    Strengths

    • Writes and summarizes inside the pages you already use
    • Q&A across your whole workspace

    Considerations

    • Full AI needs the Business plan at $20 per member
    • Only useful if your work lives in Notion

    Rytr

    For cheap short-form copy

    Rytr is a budget writing assistant for short copy, with a free plan that is useful for light use.

    Why consider it?

    The free plan includes 10,000 characters a month, 40-plus writing use cases and 30-plus languages. The Lite, Personal and Pro plans at $9, $19 and $49 a month remove the character cap under a fair-use policy. One caveat: Rytr's homepage now leads with a relationship follow-up assistant, so the writing templates are no longer the headline feature. Check that it still fits your needs before you pay.

    Strengths

    • Free plan with 10,000 characters a month
    • Paid plans from $9 a month with unlimited characters

    Considerations

    • Site now emphasizes relationship follow-ups over writing
    • Not aimed at long or nuanced drafts
