Hex

HEX is a voice dictation app for Mac and Linux. The vendor describes it as private and local: a user holds the Option key, speaks and releases, and HEX pastes the transcribed text into whatever application has focus. The download page lists version 2.1.25 for Apple silicon Macs running macOS 15 or later, with GitHub offered as an alternative download. The vendor's tagline is speak and it appears. Because it is described as local, dictation does not depend on sending speech to a cloud service, although the site gives no further technical detail such as which speech model is used, supported languages or editing commands. It suits anyone who wants to dictate into emails, documents, chat windows or code editors with a single keyboard shortcut, and who prefers a tool that runs on their own machine. The vendor does not publish a pricing page or any prices, and the site shows a download button without a signup. The Linux version is named in the page title but the home page text only describes the Mac download.
