Most AI writing tools work by sending what you type to a server. Typeahead was built the opposite way: the language model runs locally through llama.cpp, suggestions are generated and discarded in memory, and there's no server that ever sees your text.
The typical browser-extension writing assistant intercepts what you type, sends it to a remote server for processing, and streams a suggestion back. That round-trip means your draft, your emails, and your messages pass through infrastructure you don't control.
Typeahead downloads a compact language model once, then runs it locally through llama.cpp every time it generates a suggestion. There is no server in the suggestion loop at all.
Nothing here needs to be configured to be safe — these protections are on out of the box.
Typeahead never generates or shows suggestions in a password input, and there's no setting that turns this protection off.
These app categories are excluded by default, so Typeahead doesn't read or suggest inside them without you explicitly changing that.
The model runs through llama.cpp on your own hardware. Generating a suggestion never involves a network request.
There's nothing to sign into and nothing tracking what you type. The app doesn't know who you are beyond a Microsoft Store license check.
The category is full of browser extensions that route your keystrokes through a server. Typeahead doesn't.
