Speakfree

Create a local macOS application, similar to a dictation tool, that transcribes spoken words to text as the user holds down a specific key (like the Globe key). The application should run entirely offline, requiring no internet connection after the initial Whisper model download. It needs settings to allow users to change the hotkey, select different Whisper models (like tiny.en up to large), and configure punctuation handling. The transcription should appear at the cursor's location or be copied to the clipboard if no text field is active.
