About This Site
Onit is free, local, and private speech-to-text for macOS. If you've been searching for a free alternative to Wispr Flow, SuperWhisper, or Mac Whisper — one that's actually free, not a free trial, not 'free for 1000 words', not 'free if you bring your API keys' or 'free if you're technical enough to run it from code'— this is it. All processing happens on your Mac. Better than built-in Apple dictation, and it works system-wide in any app. How is it free? We make money from other paid AI tools, not from your data. Your voice never leaves your device.
