PressTalk, a private push-to-talk dictation app

Field notes

PressTalk uses a hold-to-speak workflow: click a text field, hold Fn, dictate, and release to insert the words. The page names Mail, Slack, browsers, Notes, forms, and Xcode as target environments, with copied text as a fallback when an app blocks insertion. Its speech model is about 460 MB, downloads during setup, and is described as working offline afterward. The site also states that audio and dictated text remain on the Mac.
