Typeahead

Typeahead is a macOS writing assistant that adds real-time AI autocomplete to every app on your Mac. As you type in any text field, it offers inline word and phrase suggestions you can accept to move faster, whether you're writing an email, a document, or a message. Its defining trait is privacy: the model runs locally, so your words never leave your computer, and it keeps working offline without a connection. That local-first design suits writers who value both speed and discretion and don't want their drafts sent to a cloud service. Because it's system-wide, you get the same assistance everywhere instead of only inside one dedicated editor. Typeahead is built for Mac users who write throughout the day and want quick, private phrasing help. The trade-offs are that it's macOS-only with no Windows or web version, and a local model's suggestions can be less capable than large cloud AI writers; it assists phrasing rather than drafting whole pieces.

Mac writers use Typeahead for private, offline AI autocomplete that suggests words and phrases in real time across every app.
