TalkGraph vs Otter.ai
Both listen to your conversations. One gives you an accurate transcript and summary; the other turns what was said into a living, connected knowledge base you can question later.
Choose Otter.ai if your main need is accurate, searchable meeting transcripts and quick summaries, with mature calendar and video-call integrations.
Choose TalkGraph if you want the substance of a conversation to become structure you keep, a visual map that connects to everything else you have ever discussed.
The short version
Otter.ai is one of the best-known AI meeting assistants. It transcribes calls in real time, produces summaries and action items, supports collaboration, and integrates with the major video-conferencing and calendar tools. If you need a reliable record of what was said, Otter does that job well. TalkGraph starts from a different premise: a transcript is where knowledge goes to be forgotten. Instead of a wall of text plus a summary, TalkGraph structures the conversation into typed cards (ideas, facts, decisions, actions, questions) as you speak, and connects each conversation into one cross-conversation Brain you can ask questions of.

Questions people ask
Yes, for people who care less about the transcript itself and more about turning conversations into connected, reusable knowledge. Otter focuses on transcription and summaries; TalkGraph focuses on structure and cross-conversation memory.
Yes. TalkGraph transcribes live with speaker attribution, then structures the conversation into a map as you speak.
No. TalkGraph captures your microphone or your browser tab's audio directly, so nothing joins the call as a participant.
