Free tool
Make your English sound the way you meant it.
Paste the message you were about to send. Fix the grammar, make it read naturally, make it safe to send to a client, or cut it in half. No account, five a day, free.
Free, no account, 5 rewrites a day. Your text is sent for the rewrite and is not kept afterwards.
What the four modes actually do
- Natural — for writing that is grammatically fine but reads as translated. It fixes word order, collocations and the small idiom choices that mark a sentence as non-native, without changing your meaning.
- Grammar — the conservative one. It corrects mistakes and leaves everything else alone, including sentence structure and register. Use it when you want to sound like yourself, only correct.
- Professional — for a manager, a client, or someone you do not know. Blunt instructions become polite requests; it aims for warm and direct rather than stiff.
- Shorter — cuts hedging and filler and moves the ask to the front, while keeping every name, number, date and deadline.
Why two candidates instead of one
One answer looks authoritative and hides the fact that register is a choice. Two lets you see the range — the first is straightforward, the second is a step more polished — and pick the one that fits who you are writing to. It also makes it obvious when the model has misread you, which a single confident answer does not.
The limits, stated plainly
- Five a day, 300 characters. The cap is per IP address, so a shared office or campus connection will hit it sooner than one person would.
- Your text is sent to a server. It is not kept after the rewrite, but it does leave your machine. If that is not acceptable, use a tool that runs locally.
- It edits; it does not draft. Give it something to work on. For writing from nothing, or for talking through what to say, a chat assistant is the better tool.
- It is still a browser tab. You copy in and paste back — which is the exact loop the Mac app exists to remove.
The same thing, without the copy and paste
This page is the demo. The product is a small bar at the bottom of your Mac screen: hover it, press one of your own buttons, and the text you are already typing is rewritten in place — in Mail, Slack, Gmail, Notion, Word or anywhere else you can put a cursor. The buttons are instructions you write once, and they sync to an iPhone keyboard so the same ones are there on your phone.
Frequently asked questions
Is this English rewriter free?
Yes — five rewrites a day, up to 300 characters each, with no account and no card. The limit is per IP address, so a shared office or campus connection may reach it sooner than you expect. The Mac app includes 50 rewrites a month free with no daily cap.
Will my text be stored or used to train a model?
The text is sent to the model so the rewrite can be produced, and it is not retained on the server once the response is returned. If you would rather nothing left your machine at all, Apple Intelligence Writing Tools runs much of its work on-device and is free on Apple silicon Macs.
How is this different from ChatGPT?
For a single sentence, it is not very different — this is faster to reach, but a chat assistant will do the same job. The difference shows up at volume: this tool still means copying your text into a browser tab and pasting the result back. The Mac app removes that round trip, which is the whole reason it exists.
Is it good enough for non-native English writers?
That is the case it is built for. The Grammar mode corrects mistakes while leaving your sentence structure alone, and the Natural mode fixes phrasing that is technically correct but reads as translated. Both return two candidates so you can see the range rather than accept one answer.
