Backchannel vs Grain

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 can 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. Model options include Google Gemini, OpenAI, local ONNX Whisper and Parakeet, and compatible servers such as Ollama, LM Studio, vLLM, and LiteLLM. Recordings and transcripts remain on the user’s server, according to the maker. Desktop builds are listed for Windows x64, macOS Apple Silicon, and Linux x64, with Docker Compose for full self-hosting. The free plan has no hosted tier, seat pricing, or feature paywall, though hardware and configured API usage may cost extra.

Grain is an AI notetaker and conversation intelligence platform for recording meetings and producing transcripts, summaries, insights, and coaching feedback. It supports Zoom, Google Meet, Microsoft Teams, Webex, Slack Huddles, and in-person meetings, with transcription in 130 languages. Grain can capture computer audio without a meeting bot or record video with a bot in the meeting. AI features produce notes, next steps, and automatic recaps; users can ask questions across their meeting library and get cited answers. Teams can share clips, projects, and full recordings, or configure automatic group sharing. Grain lists calendar integrations and connections including HubSpot, Salesforce, Aircall, Slack, Productboard, and Zapier. Meeting data can be exported or used with Claude, ChatGPT, and other AI tools through an MCP server and API. The desktop app is available for macOS and Windows, and the workspace is accessible in a browser. The free plan includes one notetaker seat, meetings up to 45 minutes, and a 90-day meeting history. Paid plans start at $15 a month, and a 14-day trial is listed.
