Key Takeaways
Hex is an open-source (MIT) dictation app from Anomaly, the company behind OpenCode, with no paid tier or account on its site or repo. It is the Rust rewrite of Kit Langton's Hex; his old repo is archived and points to [github.com/anomalyco/hex](https://github.com/anomalyco/hex).
Speech-to-text runs on the device with local models (Parakeet English, about 730 MB, is the default pick for English; Whisper large-v3-turbo and others are options). Audio is not saved by default, and the app only goes online for model downloads and updates.
Mac (Apple silicon, macOS 15+) is the stable app. Windows 10/11 (x64 and ARM64) and Linux are in beta. The Windows installer is not code-signed yet, so SmartScreen warns on first run (More info, then Run anyway).
Day to day: hold Option on Mac (Ctrl+Space on Windows), speak, let go, and the text pastes at the cursor. Per-app Modes, a custom vocabulary and a 7-day text history (never audio).
The optional OpenCode rewrite cleans text up with a model provider you choose, and that path sends the transcript off the device. Plain dictation does not. Version 3.1.1 shipped 2026-11-01 ([download](https://anoma.ly/hex/)).
