How Blackbird fits in
ClassMarker has no client software at all. Every control is a browser feature plus server-side randomisation, which means nothing on your desktop is visible to it.
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
- +Stay in full screen to avoid exit warnings.
- +Watch per-question timers — take a realistic amount of time.
- +Randomised answer order means reading the option text, not the letter.
- +Short quizzes fit comfortably inside the free 15-minute session.
Frequently asked questions
Can ClassMarker detect Blackbird?
No. ClassMarker runs entirely in the browser and has no visibility into desktop applications.
Does exiting full screen matter?
Yes, it is logged — but the overlay never requires you to leave full screen.
Is the free tier enough?
For most ClassMarker quizzes, yes.
Does webcam capture change anything?
Only keep your behaviour natural; the camera sees you, not your screen.
