WHAT AI REWRITE DOES

A private writing editor that runs on your computer

Choose exactly how your text should change — what to do, the tone to strike, and the length to aim for — and watch a polished rewrite stream back, all on your own device.

Rewrite by action, tone and length

Pick from ten actions — improve, simplify, shorten, expand, fix grammar, paraphrase, make it professional or casual, persuasive, or summarise — then set one of eleven tones and choose to keep, shorten or lengthen the text. The rewrite reflects exactly what you asked for.

Offline by default, private on purpose

With the local model, your text is rewritten entirely on your device — turn the network off and it keeps working. Your rewrite history is encrypted at rest and never uploaded. Cloud providers are opt-in and clearly marked.

Match my style

Paste a sample of your own writing and AI Rewrite mirrors your voice — vocabulary, rhythm and register — so the result sounds like you wrote it on a good day, not like a machine.

Your own custom tones

Define and save your own tones — “board-ready”, “warm support reply”, “punchy ad copy” — with a short description, and reuse them from the tone menu whenever you write. Add precise extra instructions for one-off requests.

Bring in whole documents

Load text straight from Word, PDF, Excel, PowerPoint, HTML, Markdown and plain-text files — image-only pages are read with built-in OCR. Long passages are split and rewritten in pieces automatically, so length is never a barrier.

History you control

Every rewrite is saved locally and encrypted, with one-click restore of the original text, action, tone and length. Set how long history is kept — a number of days, or keep it forever — and delete any entry whenever you like.

Built for flow

Copy the result, save it to a file, or send it back as the new input to keep refining — and drive the whole thing from the keyboard with shortcuts you can remap. The result streams in live, so you are never waiting on a blank screen.

Choose your model

Start free with a capable on-device model — it is selected and downloaded automatically the first time you rewrite, and a lighter model is chosen on its own for lower-memory machines. Pro unlocks premium local models and optional cloud providers for the toughest jobs.

In your language

The whole interface is available in 16 languages and follows your operating system's language automatically, with a one-click switch in Settings. AI Rewrite also replies in the same language as the text you give it.

HOW IT WORKS

From rough draft to polished text in three steps

1. Add your text

Paste a paragraph or load a document. The free on-device model downloads once on first use, then runs offline — nothing is sent anywhere.

2. Choose how to change it

Pick an action, a tone and a length — or match your own style and add a custom instruction — then press Rewrite and watch the result stream in.

3. Use it your way

Copy the rewrite, save it to a file, or feed it back in to refine further. Every version is kept in your encrypted local history for later.

WHO IT'S FOR

For anyone whose words matter

When the text is sensitive or simply yours to keep, AI Rewrite brings the AI to your words instead of sending your words to the cloud.

Privacy & compliance

Emails, contracts, reports and internal memos stay on the device — a fit for legal, healthcare, finance, government and other settings where text can't go to the cloud.

No usage fees

No per-word or per-token cloud charges. Rewrite as much as you like with the free on-device model, and keep working offline.

Faster, better drafts

Turn a rough note into a clear email, a dense paragraph into plain language, or a first draft into a confident final — in seconds, without leaving your desktop.

Your data, your models

Choose which model runs, keep your text on your own machine, and automate rewriting from the command line or an MCP-connected agent — without a third party in the loop.
