quill

Quill records a call and transcribes it without anything leaving your Mac. It's a tiny menu-bar app: one click records your mic and the call audio as separate tracks, and on stop a local speech model writes a timestamped transcript. Not the Quill.js editor; same name, different project. MIT licensed and free.

There's no app to download. You clone the repo, build it with Apple's Swift toolchain, then run sudo ./scripts/install-macos. It needs macOS 15 or later, and the first transcription pulls about 600 MB of model files. Transcription is English-only and fast on Apple Silicon. Speaker labels are just "me" and "them", because your mic is one track and everything the Mac plays is the other, notification dings included. No summaries; an on_stop hook hands the folder to your own script. Solo: free, and cheaper than Otter for raw transcripts. Teams get no sharing or sync.

The catch: it records everyone on the call with no bot and no notice to them, and in all-party-consent states like California getting permission is on you. It's also a young, mostly one-developer project with no tagged releases, and nothing has merged since September 27 while outside fixes sit in open pull requests.
