AI writing assistant with autocomplete, research, and a Chrome extension
Context-aware sentence completions appear as you type in Gmail, Google Docs, and other sites through the Chrome extension.
Generate a paragraph from a short prompt or rewrite existing text in a new tone while preserving meaning.
HyperWrite Scholar searches millions of scholarly articles so drafts can include factual, properly cited information.
Turn a few keywords into a complete, ready-to-send email reply without switching tabs.

AI autocomplete for your entire Mac, running locally and never sending your writing 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.
