Backchannel
What it is
Backchannel is a self-hosted, open-source AI meeting assistant that captures local audio and produces live speaker-attributed transcripts and meeting insights without joining calls as a bot. It works with Zoom, Google Meet, Microsoft Teams, and in-person meetings. Five live agents surface questions, objections, opportunities, and action items, while briefing lenses and an arbiter prepare a post-call summary. Users can ask questions against the live transcript while recording continues and save answers with the call. Supported model providers include Google Gemini, OpenAI, local ONNX Whisper and Parakeet, and compatible servers such as Ollama, LM Studio, vLLM, and LiteLLM. Recordings and transcripts stay on the user's server. Desktop builds are listed for Windows x64, macOS Apple Silicon, and Linux x64, with Docker Compose for self-hosting. The plan is free, with no hosted tier, seat pricing, or feature paywall.
