About Typeahead
What it is
Typeahead adds inline autocomplete to every text field on macOS — email, Slack, Notion, Docs, a code editor — accepted with the Tab key, the way an editor completes code. It runs a local model on-device with GPU acceleration, works offline, requires no account, sends no telemetry, and is sold as a one-off purchase rather than a subscription.
Why it's different
Almost every AI writing tool works by sending what you type to a server, which means your drafts, your half-written messages and whatever you paste into a text box all leave your machine. Typeahead's entire design is the refusal of that, and for anyone handling confidential material it is the only version of this feature that is usable at all. The one-off price is equally unusual in a subscription-saturated category. The cost is capability: a local model is smaller and noticeably less capable than a frontier one, so completions are shorter and less clever, and this is a Mac-only tool with no cross-platform story.
How people use it
It is most useful in the repetitive middle of writing — the second half of a sentence you have written a hundred times, standard phrasing in email, boilerplate in a document. People in law, medicine and security adopt it specifically because the cloud alternatives are off-limits. The adjustment is learning to glance at a suggestion and hit Tab without breaking flow, which takes a few days and then becomes invisible.
