Secretary42
Secretary42 is a desktop dictation application for professionals, writers, developers, and other people who want to turn speech into text while working in their usual Mac or Windows apps. A customizable global hotkey starts and stops dictation; the bundled whisper.cpp engine transcribes speech locally using downloadable Whisper models, and sends the result to the active cursor, clipboard, or a file. Users can choose models that balance speed and recognition quality and review, copy, or delete locally stored transcription history. The app is designed for drafting email, documents, notes, support replies, issue reports, and documentation. Dictation runs on the device without cloud transcription; an internet connection is used separately for checkout, license activation and checks, model and app downloads, support, and optional diagnostics. Secretary42 is available for macOS on Apple Silicon and Windows x64.
