Otter.ai

Otter.ai is a transcription and meeting-assistant service that converts spoken conversations into searchable, time-stamped text in real time. It joins video calls, records audio, and produces live notes, then generates concise summaries and highlights once a meeting ends. Users can search across past transcripts and share notes with colleagues.

The platform is built for professionals, teams, students, and journalists who rely on accurate records of meetings, interviews, and lectures. An AI chat feature lets participants ask questions about a conversation and draft follow-up content, while integrations with common calendar and conferencing tools automate joining and capturing calls.

Otter.ai offers free and subscription plans that scale by transcription minutes and collaboration features. Founded in 2016 as AISense and based in Mountain View, California, it was one of the earliest consumer-facing AI note-taking products.
