Most meeting tools are cloud services. Anarlog and Oatmeal are both exceptions, which makes the details worth getting right.
What they share
Neither sends a bot into your call. Both can transcribe and summarise on your Mac, and both keep your notes on your device by default.
Anarlog: local by default, cloud if you want it
Anarlog, formerly Hyprnote, runs models on your device on its free plan, or lets you bring your own API keys. Its Pro plan adds hosted transcription and AI, sync and collaboration. Its code is published on GitHub, so you can read how it handles your data.
Oatmeal: local, with no cloud option
Oatmeal has no cloud mode to switch on. It records your microphone and your Mac’s audio, saves as it records so a crash doesn’t lose the meeting, and shows any gaps in the audio. After the meeting it writes the transcript and summary on your Mac, with models you add, and keeps suggested decisions as suggestions until you confirm them. It’s English only.
The short version
If you want local notes with the option of cloud help, sync and collaboration, look at Anarlog. If you want a Mac app that can’t send your meetings anywhere and is careful with every second of audio, choose Oatmeal.
