Granola

Build me a local meeting-notes app like Granola for macOS. Requirements: - A menu bar app (Swift or an Electron tray app · pick the simpler to ship) with Start/Stop Recording. Record system audio + mic (use whatever screen-audio capture permission approach is standard). - On stop: transcribe the audio locally with whisper.cpp (medium model), or via OpenAI/Groq Whisper API if a key is present in .env. - Send the transcript to an LLM (key from .env) with a prompt that produces: a 5-bullet summary, decisions made, and action items with owners. - Save to ~/MeetingNotes/YYYY-MM-DD-HHMM.md: summary at top, full transcript below a divider. Keep the audio file next to it. - No accounts, no cloud storage, no telemetry. Everything stays on my machine except the API calls, and work fully offline if whisper.cpp + a local model are available. - Include a README with the permissions I need to grant and how to install deps.
