Built-in AI
Uses the AI built into Chrome. Your text stays on this device.
It needs Chrome 148 or later on Windows 10 or 11, macOS 13 or later, Linux or a Chromebook Plus, with 22 GB of free disk space and either a graphics card with more than 4 GB of memory or 16 GB of RAM. Chrome downloads the model once and shares it between sites.

Questions
Is my text uploaded?
By default it’s rewritten on our server: your text goes to Cloudflare’s AI, which sends the new version back, and nothing you send is stored. Choose This device under “Where it runs” to keep it on your computer instead. That needs the AI built into Chrome 148 or later on a computer, with enough space and memory for its model.
Do I need an account?
No. Everyone gets a free daily allowance on our server, and a free account gets six times more. The box under the tool shows how much is left today. On this device there’s no limit.
Can it turn casual writing formal, and formal writing casual?
Yes: choose Formal to tidy up a quick note for work, or Casual to make stiff writing sound like a person talking. Friendly, Professional, Confident and Diplomatic sit in between.
Which languages does it work in?
On Our server (the default), most languages, Malay included: the casual tone even sounds like everyday Malaysian Malay. On This device, Chrome’s built-in model handles English, Spanish, Japanese, German and French. English works best either way.
