Your Voice Stays on Your Device
Harker transcribes locally with Whisper, so your audio never leaves your Mac. That's the architecture, not a setting.
Download FreeMost dictation tools stream your raw audio to their servers, and you have to trust what happens to it there. If you talk through legal matters, client work, medical notes, or unreleased ideas, that trade-off is hard to accept. And cloud tools simply stop working when you're offline.
How Harker helps
Harker is local-first by design. Transcription runs on your Mac using local Whisper models (whisper.cpp), so your audio is processed on-device and never uploaded, period. The free tier requires no account and works fully offline: there's no server involved because there's nothing to send.
If you choose Premium for AI features, the boundary stays clear: only the transcribed text is sent to the cloud for transformation. It's never stored and never used for training. Compare that with Wispr Flow, which streams your raw audio to the cloud as part of its normal operation. With Harker, the most sensitive thing you produce, your voice, stays home.
This isn't a privacy mode bolted onto a cloud product. It's how Harker works, for everyone, on the free tier and on Premium.

The transcription is pasted at your cursor. Your audio never left your device.
My favourite part about Harker compared to all the other voice-to-text tools is that it's built for privacy... everything stays locally, and my thoughts and brilliant ideas are not floating around in the cloud somewhere.
