Take better notes

Private, fast, and familiar, Oats is the best way to take meeting notes on a Mac.

See all features

Local intelligence

Summaries and answers come from Apple Intelligence, Claude Code, Codex, or Ollama. Whatever you already have, nothing leaves the machine.

Feels invisible

No participant called "Notetaker" ever joins. A quiet lozenge floats over the call with record, pause, and your live note.

Private by default

No account, no cloud, no subscription. Your notes are files you own, and recording is always visible while it runs.

Powerful, yet flexible

Configure Oats so it runs the way you work.
