OpenAI trained Whisper on 680,000 hours of audio, and the small models that came out of it run on a laptop CPU in real time. That power sits idle while you pay a monthly subscription to send every voice note to someone else's server for transcription. Off Grid AI Desktop is a free, open-source app that runs Whisper directly on your Mac or PC.
