Zero dependencies
Plain Swift on Apple's frameworks — no packages you've never heard of, no supply chain to audit. Fork it and make it yours.
Free, open-source dictation for your Mac
Hold a key, talk, and the words land in whatever you're typing. One tool, one job. No subscription, no account, no middleman — audio goes straight from your Mac to AssemblyAI with your own key, and you can read every line of code that sends it.

macOS 15+ on Apple Silicon. The free-tier API key works.
Features
Dictation you can trust
No telemetry
No analytics, no crash reporting, no accounts. Blurt talks to exactly one server, and you can read the code that does it.
Native Mac app
Not a web page in a window. A small Mac app that starts fast, stays out of the way, and types into whatever has focus.
Accurate transcription
Speech in, clean text out — usually in about a tenth of a second, with 30% fewer hallucinations than Whisper. You pay AssemblyAI directly for what you use.
18 languages
Dictate in 18 languages, not just English — and code-switch mid-sentence. The model follows you between languages without touching a setting.
Real synth cues
Start and stop sounds from a real Yamaha DX7 and Roland Juno-106. There's an off switch, but why would you.
