NotchSub is a macOS app that provides live subtitles and translation for any system audio, displayed in a panel that drops down from the Mac notch. It uses WhisperKit for speech recognition and Apple Translation for on-device translation, ensuring privacy by never using the microphone or cloud services. The app is built with Swift and SwiftUI, leveraging the Neural Engine for efficiency.

Target audience: macOS users, language learners, developers interested in on-device ML
