Live dictation vs batch transcription
MacWhisper is built for transcribing finished audio files. Jarvis is built for live, in-the-moment dictation. Press the hotkey, speak, release, text appears wherever your cursor is.
Voice control
Jarvis adds voice commands MacWhisper doesn't have: "switch to Slack", "open the design channel", "reply to that email". You drive Mac apps with your voice.
Pricing
MacWhisper: free tier + one-time paid models. Jarvis: free, open source, all features.
Use cases
For transcribing podcast episodes or interview recordings, MacWhisper. For replacing your keyboard for daily writing + Mac control, Jarvis.
