RewriteMate

RewriteMate is a menu bar app for macOS. Select text in any app, press one shortcut, and RewriteMate rewrites, shortens, fixes the grammar, or applies your own instruction — then puts the result back in place.

How it works

• RewriteMate Cloud — sign in with Google or Apple and use the hosted models. No API key needed; a free plan covers everyday use.
• Your own API key — send text straight to OpenAI, Anthropic, Google, OpenRouter or another compatible provider.
• On this Mac — run a small model locally; no network and no key.

Privacy in one line

Only the text you ask to rewrite leaves the app, and only when you use Cloud or an API key. See the Privacy Policy for exactly what is sent.
