Vexa started life as a Chrome extension for Google Meet that layered live transcription, instant Q&A and a cross-meeting knowledge base onto calls without joining as a separate bot participant. That extension remains available on the Chrome Web Store, and it is still how a lot of individual users first meet the product.
The bigger story today is infrastructure. Vexa is now an Apache-2.0 open-source meeting bot API: you send one API call and a bot joins a Google Meet, Microsoft Teams or Zoom call, streams a speaker-attributed transcript over WebSocket while the meeting is still running, and captures audio for storage. The stack ships with webhooks, Postgres-backed storage, an MCP server for agents like Claude Code and Codex, and a forkable Next.js dashboard. Because it is open source, teams that need full control can run the whole thing in their own cloud with their own transcription model.
Buying options span the free end to enterprise. Developers self-host from GitHub at no licence cost, individuals pay per seat to connect their agent over MCP, and builders pay per bot-hour for the hosted API. An enterprise track covers self-installation with security and data-residency review plus a fixed-fee activation sprint. The company also markets a version tailored to fund distribution, private credit and wealth management.
