Hex
Local dictation: hold a key, speak, let go – the text lands directly in any app.
Hex converts your speech to text on your own computer and pastes it straight into whatever app is active, whether that's email, chat or a word processor. On first launch, Hex downloads a speech model. After that, according to the developers, nothing leaves your machine. The app is written in Rust, MIT-licensed and comes from the team behind OpenCode. You'll find new experimental features at the bottom of the sidebar under "Labs".
