Invisible AI used to mean a paid overlay. Ofradr is a free invisible AI overlay: cross-platform on Windows and macOS, click-through, not sitting in the tray as a neon logo. Ultra is included. Source is on GitHub.
Built as a system overlay, not a browser extension a proctor panel can list.
No stealth tax. The same Ultra grant covers overlay time.
Open source at sunnycodet/ofradr so “invisible” is not marketing fog.
Vendors charge extra for “stealth mode.” Ofradr’s overlay is the default app, and the app is free. You are not unlocking invisibility behind Elite.
Use it for practice and for environments where you are allowed assistance. The overlay being invisible does not change the rules of a test.
A lightweight native window that does not show up the way a Chrome popup does. Works across Zoom, Teams, Meet, and browser IDEs. Pair it with local models if the network is watched.
Ofradr. Ultra is free forever and the overlay is the core product, not an add-on.
