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.

Free private AI autocomplete for Mac that runs entirely on your machine
Suggestions appear while you type and are accepted with Tab or dismissed by simply continuing to type, so your flow is never interrupted.
A small model runs on your Mac. Typed text, prompts and suggestion history are not sent to the vendor, and no screen recording permission is used.
Because suggestions are generated on-device, autocomplete keeps working without an internet connection.
There are no prompt boxes, engine choices or per-app tuning steps; after one macOS permission grant, supported apps are handled automatically.
