ghostmeet

ghostmeet is an open-source AI meeting assistant for browser-based calls and other audio playing in a Chrome tab. It provides live captions and on-demand summaries while keeping audio on the user’s machine.

Its transcription pipeline uses Whisper through faster-whisper, with captions updated every 10 seconds. The summary feature uses Claude on demand and can produce structured output with key decisions, action items, and next steps. It also accepts meeting context such as an agenda, a design document, or a prior transcript, which the summarizer reads before generating the summary. The product states that no bot joins the call and that it runs invisibly to others as a Chrome side panel. It also says the meeting itself does not know it is there.

ghostmeet works from any browser tab that plays audio, including Google Meet, Zoom Web, Microsoft Teams Web, Discord, Around, Whereby, recorded talks, podcasts, and training videos. The page says the browser extension captures the tab’s audio stream directly with no microphone or screen capture, then sends audio frames over WebSocket to a FastAPI backend on localhost. Native Zoom and Teams desktop apps are not supported; the web clients are used instead. The backend can also be hosted on a separate machine, and the install is described as a one-line Docker setup followed by loading the Chrome extension manually.

The project is licensed MIT and described as open source. It notes that accounts are not required. The default Whisper model is the base model, which is said to run on CPU, while larger models are also available.
