No. Google Forms cannot detect tab switching, and never has. Nothing in the response data records it, and there is no setting that enables it.
Browsers do expose the event — a page can tell when it becomes hidden, through the
visibilitychange event. Google simply does not use it in Forms, which is
built as a survey tool rather than an exam tool.
Proctoring add-ons put the form inside their own page and listen for that event there. When the tab is hidden they record it, along with how long it lasted, and show the count to whoever set the quiz.
The detail most write-ups skip: many tools embed the form in an iframe pointed at google.com. Because that iframe belongs to a different origin, the surrounding page is blocked from seeing anything inside it. So the tool can tell that the whole tab was hidden, and nothing more — a click inside the form, a paste into an answer, and time spent per question are all invisible to it.
Detecting a paste or a copy requires the tool to render the questions itself rather than embed them.
Switching away is also a noisy signal on its own. A notification, an incoming call, or a permitted second tool all produce it. What is worth attention is the pattern — a long absence, or a switch immediately followed by a large paste — not the raw count.
With a normal Google Form, nothing is being recorded, and no honest tool should imply otherwise. Where proctoring is in use, respondents should be told before they start — which is both fair and, in most jurisdictions, required.
AI Forms for Google Docs does this from your phone — no add-on, no laptop. Get it on the App Store.
