How Blackbird fits in
Everything HackerEarth records comes from JavaScript events inside the exam tab plus a webcam snapshot. Its strongest signal by far is a large paste into the editor.
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. Since the assistance is read off-screen and typed by you, there is no paste event to flag.
Practical tips
- +Never paste — type the solution, even if slowly.
- +Stay in full screen; exiting is logged.
- +Vary naming and structure so plagiarism comparison finds nothing identical.
- +Use the humanised auto-typer if you want realistic keystroke timing.
Frequently asked questions
Can HackerEarth see the overlay?
No. It has no screen capture beyond the webcam snapshot, and the overlay is excluded from capture anyway.
What about paste detection?
Blackbird's auto-typer sends real keystrokes with human timing, jitter and occasional corrections, not a clipboard paste.
Will plagiarism checks catch a model-written answer?
Rewrite structure and names in your own style. Submitting a verbatim model answer is the risk, not the tool.
Does it work in the HackerEarth IDE?
Yes, it works over any window, including the browser IDE.
