How to Use Blackbird with Safe Exam Browser
Safe Exam Browser is the open-source kiosk used across European universities and Moodle deployments.
What Safe Exam Browser enforces
- —A locked-down kiosk desktop with no task switching
- —A configurable list of prohibited processes, terminated on sight
- —Disabled clipboard, print screen and context menus
- —A config key handshake with the exam server
- —Optional screen-proctoring add-ons
How Blackbird fits in
SEB is client-side and configuration-driven: the institution writes a list of banned process names and SEB enforces it. It is strong against well-known apps and blind to anything not on the list.
Blackbird is a lightweight native Windows overlay drawn at the system compositor level. It is not a browser tab, an Electron window, or a shared surface, so it does not show up in screen recordings, screen-share streams, or active-window checks. It stays on top, accepts clicks without stealing focus, and disappears instantly with a hotkey.
Practical tips
- +Launch Blackbird before SEB starts and keep it hidden until you need it.
- +Never alt-tab — SEB logs that, the overlay does not require it.
- +Prefer text capture over screenshots inside SEB's protected surface.
- +Point Blackbird at a local model if SEB's network profile blocks outbound traffic.
Frequently asked questions
Can SEB kill Blackbird?
SEB terminates processes on the institution's prohibited list, which targets remote-control, chat and recording software. Blackbird is not on those lists.
Does the overlay appear in SEB's screen proctoring?
No. Screen-proctoring add-ons capture the display through standard capture APIs, which exclude Blackbird.
Can I use it offline?
Yes, with a local Ollama model. Nothing leaves your machine.
Windows only?
Yes, Blackbird runs on Windows 10 and 11.
