Meeting Copilot — Demo video

Meeting Copilot is a read-only meeting assistant for Hermes Desktop on macOS. It combines meeting transcription, user-triggered answer suggestions, selected project evidence, and a floating overlay. Nothing is spoken, posted, or sent to the meeting automatically. Existing work: the project began before this hackathon as a Hermes Desktop prototype using Meetily transcripts and project files. Hackathon additions: independent macOS audio capture; Meta Muse Voice transcription and Muse Spark answer integrations; the native meeting overlay; a standalone answer core; interface, consent and lifecycle improvements; request-scoped exclusion of past sessions; and regression tests across Linux, Windows and macOS. Local faster-whisper transcription is also supported. The attached UI walkthrough records the real installed app with a fictional Cedar project, past sessions excluded, web search off, and capture paused. It shows real file retrieval and the actual failed Meta answer request, rather than a simulated answer. A separate local audio rehearsal produced incomplete, inaccurate transcription and dropped-frame warnings; successful live Meta transcription is not claimed. Overlay screen-share exclusion is best-effort. Creator explanation, supplied by Adam: https://youtu.be/EacIZXbqDeI
