Open-source macOS app
Write That Down
A menu-bar app that detects calls, transcribes microphone and system audio with local models, and saves structured Markdown notes.

Why it exists
Meeting capture often sends sensitive audio through a cloud service. Write That Down explores a local alternative: capture the call on the Mac, transcribe it on-device, and leave behind ordinary Markdown.
What I built
- Built a native menu-bar experience with SwiftUI and AppKit.
- Captured microphone and system audio with ScreenCaptureKit.
- Integrated local transcription through WhisperKit.
- Kept the workflow account-free, local, and compatible with plain Markdown tools.
Evidence
The complete macOS implementation is published on GitHub.
It is designed for private, account-free capture, with audio and transcripts kept on the Mac.
