Caret
Rewrite any text without sending it to a server.
The problem
Editing one sentence means switching to a chat window and pasting your text into someone else’s server, then pasting the result back.
That’s a lot of overhead for a small edit, and some text, like client work or unpublished notes, shouldn’t leave the machine at all.
The approach
Chrome now ships Gemini Nano on device. Caret puts it behind a hotkey: copy text, press the shortcut, pick a transform, paste the result. No tab switch, no network.
Each transform is a prompt you can edit. The defaults cover rewrite, shorten, formalize and explain, and you can add your own to the list.
How it works
Built-in transforms
Outcome
An extension with no backend, no account and no network calls. The model runs in the browser, so it behaves the same offline as online.
