Ghostbar is a macOS menu bar AI client invisible to screen sharing.
Zoom, Teams, Meet, OBS, QuickTime ā nobody sees it but you. Uses NSWindow.sharingType = .none to remove the window from macOS's compositor before any recorder touches it.
What makes it different:
ā Native Swift ā ~5MB vs 150-500MB Electron alternatives
ā Ollama, OpenAI, Claude, OpenRouter, LM Studio, llama.cpp
ā On-device voice input via Whisper
ā Zero telemetry, no account, MIT license, free forever
