Writing in a non-native language means constantly second-guessing your phrasing. AI Rephrase fixes that — select awkward text anywhere (Slack, email, docs, IDE), press one shortcut, and it gets rephrased in-place.

Everything happens locally — through Ollama or Apple Intelligence. Your text never leaves your Mac. No API keys, no cloud, no subscriptions.

Ollama is the recommended backend. Apple's on-device model (~3B) struggles with non-English text, tends to answer questions instead of rephrasing them, and frequently triggers false-positive content filters. Ollama with a model like gemma3:12b handles all of this without issues.

All rephrasings are saved in a persistent, searchable history window so you can review or reuse them later.

Apple Intelligence (limited)

The built-in Apple model is small (~3B params). It only supports English, may refuse to process some text, and sometimes answers questions instead of rephrasing them.

  1. Open System Settings → Apple Intelligence & Siri
  2. Turn Apple Intelligence on
  3. Set both Mac language and Siri language to English (US)
  4. Wait for the on-device model to download
