Best AI writing tools (2026)

Updated 2026-11-09 · Scores from our writing rankings

Short answer: draft with ChatGPT or Claude, then polish with Grammarly. In our rankings ChatGPT scores 9.3/10 and Claude 9/10 as general assistants, and Grammarly is the top dedicated writing tool at 8.9/10. For rewording use QuillBot, for fiction try Sudowrite, and for marketing copy look at Jasper.

"AI writing tool" covers two different jobs. Some tools write a first draft from your notes: emails, blog posts, reports and stories. Others improve text you already wrote: grammar, tone, clarity and length. Most people get the best results by pairing one of each. Below is how the strongest options compare in our rankings and which kind of writing each one suits.

How we score

Every tool on AI Agent Ideas gets three ratings out of 10: usefulness, ease (how quickly a beginner gets results) and trust (track record, data handling and reliability). These combine into one overall score. Sponsors and affiliate links never change a score. Read more on how rankings work.

AI writing tools at a glance

1. ChatGPT: best all-round drafting tool

ChatGPT scores 9.3/10 (9 useful, 10 ease, 9 trust). Our verdict: "The default all-rounder: chat, images, files and code in one app. Best first assistant for most beginners." For writing, paste your notes, say who the reader is and what tone you want, and ask for a short draft you can edit. Pricing: Free to start, paid plans.

2. Claude: best for long documents and natural drafts

Claude scores 9/10. Our verdict: "Anthropic's assistant for writing, analysis and code, now with decks, spreadsheets and scheduled tasks. A top pick for long documents and careful reasoning." Choose it for reports, long articles or when you want to feed in a lot of source material at once. A common setup is to draft in Claude and use ChatGPT for quick rewrites, or the other way round.

3. Grammarly: best for fixing what you already wrote

Grammarly scores 8.9/10, with a 10/10 ease rating. Our verdict: "Everywhere-you-type grammar and tone fixes: the safest first writing tool." It works in your browser, email and documents, so it catches mistakes without changing how you work. Pricing: Free, Pro plans.

4. Gemini: best if you write in Google Docs and Gmail

Gemini scores 8.6/10. Our verdict: "Google's assistant, strongest if you live in Gmail, Docs and Drive." If most of your writing already lives in Google's apps, it saves copying text back and forth.

5. QuillBot and Wordtune: best for rewording sentences

QuillBot (8.2/10): "Quick paraphrasing, summarising and grammar checks for students." Wordtune (8.2/10): "Rewrites sentences to sound clearer and more confident. Light and handy." Both are lighter than a full chatbot and handy when one paragraph just reads wrong.

6. Jasper: best for marketing teams

Jasper scores 7.6/10. Our verdict: "Marketing copy with brand voice and team workflows." It makes most sense for teams producing a lot of on-brand copy. Pricing: Paid plans, trial.

7. Sudowrite and ProWritingAid: best for fiction and long-form

Sudowrite (7.6/10): "Built for fiction writers: brainstorming, describing and drafting chapters." ProWritingAid (7.6/10): "Grammar and style editor with AI help, built for fiction and long-form writers." Use Sudowrite to get unstuck and ProWritingAid to tighten the finished manuscript.

8. AudioPen: best if you think better out loud

AudioPen scores 7.3/10. Our verdict: "Turns rambling voice notes into clean, readable text in a style you choose, on web, phone and desktop." Talk through an idea on a walk and get a tidy first draft back. Pricing: Free plan; Prime $99/yr.
