3. Why should this project be added: Inscribe is a private, on-device transcription and note-taking app for macOS (and iPhone/iPad). Its core function is recording and transcribing meetings, lectures, and interviews using local, on-device speech-to-text models — a specialised ML task that runs entirely on the user's machine with no cloud upload. Per the guidelines, this is "leveraging local, specialised ML models as part of a larger process," not a prompt wrapper or chatbot. It fills a gap in the Audio section as a fully offline, privacy-first transcription tool. It's a commercial app with a free tier, so maintainers can install and validate it at no cost (no OSS/Freeware icon applies).
