Testportal cannot magically see an entire computer through a normal browser tab, but it can react to events that websites are allowed to observe. The most common signals are tab visibility changes, window focus loss, fullscreen exits and time spent away from the active test page.
That difference matters. A realistic understanding of detection is more useful than myths about hidden screen access, and it also helps students use AI tools more responsibly for preparation and review.
Try QuizSolver in practice
Open demoWhat Testportal can usually detect
A web quiz can know that its tab is no longer active or that the browser window lost focus. That does not reveal exactly what the user did, but the platform may log it as leaving the test environment.
- switching to another tab or app
- leaving fullscreen mode
- focus loss events
- time away from the active test tab
What a normal website cannot see
Without a separate proctoring app or browser-level permission, a website cannot read the list of open programs, inspect unrelated tabs, access local files or silently watch the full desktop. Browsers intentionally block that kind of access.
Where extensions fit in
A Chrome extension runs in the browser, but that does not mean the quiz page automatically knows every extension installed by the user. Detection is usually indirect: focus changes, unusual page behavior, pasted text patterns or external proctoring software.
Safer AI use for Testportal
The safest way to use AI is before and after assessed attempts: save practice questions, read explanations, create notes and turn weak areas into review quizzes. QuizSolver history is built for that study loop.
