AI meeting agent that transcribes, summarises, and turns every conversation into searchable knowledge
Live transcription in multiple languages with speaker identification, so meeting records are accurate and attributable.
Each meeting becomes a clear summary with decisions, action items, and insights, with next steps captured and assigned automatically.
Ask questions across your meetings and connected apps to instantly produce follow-ups, reports, and content.
Get briefing documents before a meeting and real-time, personalised coaching during calls based on your history and playbooks.
Graph, vector and text retrieval for AI agents on your Postgres
Query graph, vector, full-text and hybrid retrieval through one consistent interface instead of stitching multiple systems together.
The open-source pgGraph engine follows relationships across your records, enabling multi-hop and shortest-path retrieval without moving data.
Semantic search over embeddings combines with sparse and full-text matching so queries that mix meaning and exact terms still work.
A dashboard playground, CLI for imports and configuration, and a typed Python SDK make it straightforward to prototype and then ship.
