Introduction to trnscrb

trnscrb is a macOS application designed for local meeting transcription, offering a private and secure way to capture audio from meetings without relying on cloud services. It runs in the menu bar and automatically detects popular meeting platforms such as Zoom, Google Meet, Microsoft Teams, Slack, and FaceTime. Using the Whisper model on Apple Silicon, it performs on-device transcription, ensuring that no data is sent to external servers. Transcripts are saved as plain text files with speaker diarization, making them easy to review and manage.

The integration with Claude Desktop enhances the user experience by enabling search, summarization, and extraction of action items from past meetings. This makes trnscrb an ideal tool for professionals who value privacy, control over their data, and seamless workflow integration. With no need for an account or subscription, trnscrb provides a straightforward solution for meeting transcription on macOS.
