Fully on-device dictation you pay for once, not monthly
Open source
About VoiceInk
VoiceInk does everything on your Mac: local Whisper models transcribe your voice with nothing sent to a server, ever. For privacy-focused users it's the easiest recommendation in the dictation space.
It's open source, so the sceptical can read the code or build it themselves for free. Model choice lets you trade speed against accuracy for your machine.
The $29 one-time licence for one Mac undercuts every subscription rival by a wide margin. Development is active, and the community around it keeps growing.
