Otter.ai is the best-known AI meeting transcription tool: it joins your calls, transcribes them in real time, and generates summaries and action items, with per-month transcription minute limits.

Common audio and video files can be attached to the chat and transcribed with /transcribe.
Yes, run /summarize or ask any of the 400+ models for action items, summaries or a follow-up email.
