Typeahead
AI autocomplete for your entire Mac, running locally and never sending your writing to a server
Sentence completion where you already type
Faint ghost text completes the word or sentence you are typing right at the cursor. Tab accepts the entire suggestion, the right arrow takes just the next word, and Esc dismisses it so you stay in control.
Private by design and offline capable
The model runs on your Mac rather than in the cloud. Typeahead never sends your writing to a server and keeps working offline after setup, which makes it suitable for work email and sensitive documents.
Screen and clipboard context
It reads what is on screen and what you copied to the clipboard, so replies fit the thread you are actually answering rather than being generic filler.
Per-app writing styles and your own colour
Set a voice per app, professional in Mail and friendly in Messages, choose from seven color-blind-safe highlight shades, and tune suggestion timing to instant, balanced or only when you pause.

Limitations
–Currently Mac-only, so Windows, Linux, iOS and Android users cannot use it
–The site still shows a waitlist alongside 'Get Typeahead', which can suggest availability is being rolled out gradually
–Because it only completes text where you already type, it will not draft a long document or research a topic for you the way a chat assistant will
–Per-app writing styles and learned phrases take a little setup before the suggestions feel genuinely personal
–Payment structure is described only as paid, without an obvious free tier for long-term use
