Free online AI text rewriter: make text clearer, more formal, shorter or friendlier — 100% on your device, no upload, no account.

🔒 Runs entirely in your browser — your files never leave your device.

About AI Rewriter

AI Rewriter improves your text — make it clearer, more formal, more friendly, shorter, or more detailed — using an AI model that runs on your own device. Choose between Chrome's built-in AI (Gemini Nano, when available) and an open LiquidAI LFM2.5 model compiled to WebAssembly (230M or LFM2-VL-450M — your choice), which works in any modern browser. The WebAssembly model (about 150 MB) is downloaded once and cached locally.

How to use AI Rewriter

  1. Drop your file(s) into the upload area, or click it to browse.
  2. Adjust the options if needed.
  3. Click the action button and download the result — processed locally, in seconds.

Frequently asked questions

Is AI Rewriter really free?

Yes — completely free, with no account and no usage limits. The AI runs on your own device.

Is my text sent to a server?

No. Both engines (Chrome's built-in AI and the local WebAssembly model) run entirely on your device. Your text never leaves your computer.

Which browsers are supported?

The WebAssembly model works in any modern browser (Chrome, Firefox, Safari, Edge). Chrome's built-in AI additionally requires a Chrome version that ships the on-device model.
