The Why
Typing is a bottleneck. You think faster than you type, and every time you context-switch to write something — a Slack message, a code comment, an email — you lose momentum. The Fn key on your Mac keyboard is sitting there doing nothing.
VoiceInk hijacks the Fn key system-wide and turns it into a dictation trigger. Hold to record, release to transcribe — your words appear in whatever field you were focused on, already cleaned up by AI. The entire tool fits in 5MB, idles invisibly.
What it does
Hold Fn to record, release to transcribe. Works system-wide in any app — browser, editor, Slack, email — with no window focus required.
Audio streams to Deepgram as you speak, returning live interim results. No waiting for the recording to finish — transcription starts mid-sentence.
Hold Shift+Fn to activate AI rewriting — Groq rewrites your raw speech into clean prose in under 400ms, fixing filler words and run-ons automatically.
Transcribed text is injected directly into whatever text field you were using. No clipboard conflicts, no switching focus — it just appears.
No internet? VoiceInk falls back to a local Whisper model, running entirely on-device. Full dictation functionality with zero network dependency.
Built with Tauri v2 and Rust — idles under 20MB RAM with a sub-5MB binary. Lives quietly in your menubar until you need it.
