Typeahead is a system-wide AI autocomplete app for Mac that completes your sentences inside the apps you already use, running entirely on your machine so your writing is never sent to a server.
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.
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.
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.
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.
