Most AI writing help lives in a separate window: you write a prompt, wait, then copy the answer back. Typeahead puts the help at the cursor instead. You start the sentence, the rest appears in grey and Tab takes it. You stay the author: it finishes the sentences you start, in your words.

It works in every app on your Mac, from a quick Slack reply to a long email in Mail. It reads the window you are in, so suggestions fit the conversation. Each app can have its own writing style, and Typeahead learns how you write, on your Mac.

It suits people who cannot paste client or patient writing into a web tool. Typeahead runs on a local model. Your writing never leaves your Mac. Typeahead 2.0 was No. 2 Product of the Day on Product Hunt on July 6, 2026.
