Write — Fix, Translate & Rewrite Text Privately

Overview

Write fixes grammar, translates and rewrites text without any of it leaving your device. Paste something and it runs straight away; Cmd or Ctrl and Enter does the same, and Paste & run reads the clipboard in one click. Where your browser ships its own on-device AI — Chrome’s translator since version 138, its general writing model since 148 — nothing is downloaded at all. Where it does not, a small language model can be fetched once and then works offline. Beyond fixing and translating, the same text can be made more formal, more casual, shorter or longer, and long documents are handled paragraph by paragraph rather than truncated. Results stream in as they are written, can be stopped, copied, saved or pushed back into the input to chain another change, and every past run stays in this browser alone.

Proofreading something confidentialFix a contract, a medical note or a performance review without a copy of it reaching a cloud service.
Translating on the moveGet the language pack once and translate on a plane, on a train or on a locked-down network.
Changing the registerTurn a blunt message formal before sending it, or a stiff one warmer, without rewriting it yourself.
Tightening long writingPaste several pages and have each section shortened in place, with the structure preserved.
Writing in a second languageDraft freely, then fix the grammar locally instead of pasting your work into an online checker.

How it works

Paste your text

Pasting runs the current action immediately — that is the whole point. Cmd/Ctrl + Enter runs it too, and Paste & run reads the clipboard and starts in one click.

Pick what to do

Fix and Translate are the two main verbs. Formal, Casual, Shorter and Longer rewrite the same text a different way. Switching action re-runs on the text already there.

The best available engine runs it

The tool checks what your browser offers. If it has built-in AI, nothing is downloaded at all. If not, a small model can be downloaded once and then works offline.

Keep the result

Copy it, save it as a text file, or push it back into the input to run another action on it. Past runs stay in History, on this device only.

Frequently asked

Does my text leave the browser?

No. Every engine runs on your own device. The only network traffic is the optional, one-time download of a language pack or a model, and only after you click to allow it.

Do I have to download anything?

Often not. Chrome 138 and later can translate on-device, and Chrome 148 and later includes a general writing model. When your browser has neither, the tool offers a small model — a few hundred megabytes, downloaded once.

Why does it say my browser has the AI but cannot use it?

The browser ships the interface before the model. Chrome only installs its on-device model when there is enough free disk space, so the API can exist while the model is still unavailable.

How long a text can I paste?

Long ones are fine. Text beyond an engine’s limit is split on paragraph boundaries, processed section by section, and joined back together with the original spacing intact.

Why do I sometimes get one answer instead of several?

The browser’s translator and proofreader are deterministic — asking twice returns the same string. The tool says so rather than showing you identical alternatives.

Can I use it offline?

Yes, once whichever engine you use has its files. After that the tool works with no connection at all.

Where is my history kept?

In this browser’s local storage, never on a server. Clear it any time from Settings.
