The best AI tools for writing and communication
AI can draft an email in seconds, tidy up a messy paragraph or help you sound natural in a language that isn't your first. But it can also make everyone sound the same. Here are the four tools worth using, and how to keep your own voice.
Our picks
Two all-rounders for drafting, and two specialists for polishing.
Best all-rounder for drafting
1. ChatGPT by OpenAI
The most widely used AI chatbot, and the easiest place to start. It handles everyday questions, writing, analysis, images and voice conversations in one app. OpenAI is now rolling out its newest model, GPT-6, to everyone in ChatGPT.
- Strong at almost everything, with the biggest range of features
- New "Intelligent UI" answers can include visuals and interactive elements
- Voice mode for hands-free conversations
Watch out: Free-plan limits are tighter on the newest model at busy times.
Price: Free plan; paid plans from about $20/month (varies by country)On: Web, iPhone, Android, Windows, Mac
Best for long documents and a natural tone
2. Claude by Anthropic
A thoughtful, careful assistant that is especially strong at writing, analysing long documents and coding. Independent benchmarks from Artificial Analysis currently rate Anthropic's Claude Opus 5.5 and Sonnet 5.5 as the most capable AI models available.
- Top-rated model quality in independent benchmarks (October 2026)
- Natural, well-structured writing and editing
- Handles very long documents and complex coding tasks
Watch out: The free plan has lower usage limits than some rivals; heavy users will want a paid plan.
Price: Free plan; Pro from $20/month, Max plans for heavy useOn: Web, iPhone, Android, Windows, Mac
Best for polishing as you type
3. Grammarly by Grammarly
Checks spelling, grammar and clarity as you write in your browser, email and documents, and suggests clearer wording. AI prompts help you draft and rewrite text.
- Works in most apps and websites you already use
- Free plan catches mistakes and includes 100 AI prompts a month
- Pro adds full-sentence rewrites, tone changes and plagiarism checks
Watch out: It reads what you type in order to make suggestions, so check your employer's rules for confidential work. Accepting every suggestion can flatten your own voice.
Price: Free plan; Pro $12/monthOn: Web, Windows, Mac, iPhone, Android
Best for writing in a second language
4. DeepL Write by DeepL
Corrects and improves your writing and suggests more natural ways to phrase it, in a style and tone you choose. Works in English, Chinese, French, German, Italian, Japanese, Korean, Portuguese and Spanish.
- Makes text sound natural, which is ideal if English is your second language
- A "corrections only" mode if you just want mistakes fixed
- Free for short texts, no account needed
Watch out: No Indian languages yet. The free version handles up to 1,500 characters at a time.
Price: Free for short texts; DeepL Write Pro for unlimited useOn: Web, Desktop app
How to choose
- Need a first draft of an email, post or report? ChatGPT or Claude. Claude often sounds more natural in longer pieces.
- Want mistakes caught wherever you type? Grammarly.
- Writing in English (or another language) that isn’t your first? DeepL Write, to make it sound natural.
Keep your own voice
Give the AI your notes, your key points and an example of how you write, then edit what it gives you. Readers can often tell when text is fully AI-written, and it works best as a helper, not a ghostwriter. Never paste confidential work information into a tool your employer hasn’t approved.
How we pick
Features and prices come from each tool’s official pages, checked on the date shown on each card, and we only include tools that independent reviews also rate well. No tool pays to be listed. See how we pick across all jobs.
