A few things I expect to come up:
- Privacy: nothing leaves your device.
- Other options (like Otter or Granola): AudioTap is not cloud-based, recordings are yours as local files (instead of a limited access to the transcripts), no extra non-identifiable data analysis to train anything else, offline first (although use case is online calls) and one-time payment vs subscription.
- It uses stereo channels to identify you (as [Me]) and analyzes voice embeddings to cluster other speakers in the system-audio channel (letting it know how many speakers were in the call significantly improves diarization).

Happy to go deep on any of these.
