Both listen to your conversations. Otter gives you an accurate transcript, summary and tracked action items, connected to the tools your team uses; TalkGraph turns what was said into a visual map that joins everything else you have discussed.
Recording meetings: a transcript, a summary and action items for each call, connected to the team's calendar and tools.
Turning any conversation into a visual map as you speak, one that joins everything else you have discussed and that you can ask later.
Otter.ai is one of the best-known AI meeting assistants. It transcribes calls in real time with speaker identification, writes summaries with decisions and action items, assigns and tracks those action items, and integrates with Zoom, Google Meet, Teams, calendars and more than 50 other tools. It can join a call as a bot or, with its desktop app, record without one, and since April 2026 it links meetings into a cross-meeting knowledge engine you can chat with. TalkGraph starts from a different premise: instead of a transcript plus a summary, it structures the conversation into a live visual map of typed cards (ideas, facts, decisions, actions, questions, risks) as you speak, and every map joins one cross-conversation Brain that you can explore and ask.

Yes, for people who care less about the transcript itself and more about seeing conversations as structure and connecting them over time. Otter focuses on transcripts, summaries, tracked actions and integrations; TalkGraph focuses on a live visual map and a cross-conversation Brain.
Yes. TalkGraph transcribes live with speaker attribution, then structures the conversation into a map as you speak.
No. TalkGraph uses your microphone, or on desktop Chrome and Edge your browser tab's audio, so nothing joins the call as a participant. Otter's desktop app can also record without a bot.
Try it with no signup - talk for a minute and watch it structure itself.
