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.

Run and scale durable AI agents on your own infrastructure
Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.
