MacWhisper and Oatmeal share a principle: transcription should happen on your Mac. What they build on top of it is different.
MacWhisper: a transcription toolbox
MacWhisper transcribes files, calls and dictation on your Mac in over 100 languages, recognises speakers and can translate. It can record calls in the background without a bot. For summaries and chat, you connect an AI provider with your own key, or a local AI app.
Oatmeal: a meeting notebook
Oatmeal is built around the meeting. Your own note is the page; the transcript, summary and suggested decisions sit beside it. Summaries are made on your Mac with models you add, each part points back to what was said, and decisions only count once you confirm them. You can search every meeting at once. It’s English only.
The short version
If you need a flexible transcriber for any audio in any language, choose MacWhisper. If you want a private home for your meeting notes, choose Oatmeal.
