One-click AI assistant for browsing, writing and research
A Chrome extension that summarizes, searches and writes directly over the page you are on, without switching tabs.
Access to leading models from several vendors in one place, so you can pick the best fit for each task.
Build reusable knowledge bases from your own documents and code, then query them repeatedly for tailored answers.
Turn a prompt into flowcharts, mindmaps, charts and other diagram types for reports and presentations.

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.
