Local-first voice dictation for Mac, Windows and Linux from the OpenCode team
Hex is a local-first voice dictation app from Anomaly, the team behind OpenCode. Hold a shortcut (Option on Mac, Ctrl+Space on Windows), speak, and Hex transcribes on-device and pastes the text into the focused app. It is built in Rust, streams transcription while you speak, needs no cloud transcription service, and offers Modes for corrections, app-specific behavior and optional OpenCode-powered rewriting. The macOS app is available for Apple silicon, with Windows and Linux betas; source is on GitHub.
