Otter.ai

Otter.ai is a meeting assistant that joins calls on Zoom, Google Meet, and Microsoft Teams to produce a live transcript, then turns that transcript into a summary with speaker labels, highlights, and action items once the meeting ends. It works from a web app, mobile app, or browser extension, and there's an API for teams that want to pipe transcripts into other tools. Notes sync automatically to Slack and Notion, and the OtterPilot agent can answer questions about past meetings or draft follow-up emails based on what was discussed.

It's built for people who sit in a lot of meetings and don't want to choose between participating and taking notes: sales teams logging call details into a CRM, researchers running interviews, journalists doing recorded conversations, and product or engineering teams that need a searchable record of decisions. Because it transcribes in real time, participants can see captions and a rolling summary during the call itself rather than waiting for post-processing.

What separates Otter from a plain transcription tool is the layer built around the transcript: automatic speaker identification trained on a person's voice over repeated meetings, a chat interface for querying meeting history, and channels that group and share notes with a team the way a shared doc would. It was one of the earlier products to popularize live AI meeting notes, and that head start shows in how deeply it integrates with everyday calendar and messaging tools rather than existing as a standalone recorder.
