Detecting invisible AI overlays without intrusive system drivers

Why a dedicated desktop workspace catches floating AI assistants cleanly—without installing permanent background software on a candidate’s laptop.

A candidate taking an assessment on their own computer should not have to install permanent background software to prove their work is their own.

Why browser tabs are blind

A web browser tab is isolated by design. It cannot see whether a second display is connected, whether the desktop is being streamed over a background broadcast app, or whether a transparent window is floating directly above the test questions.

Clean desktop protection

The Clevid desktop client runs as a standard desktop application only while the assessment is open. Before Question 1 loads, preflight verifies connected displays, camera readiness, and virtual machines. During the session, any unauthorized overlay sitting above the workspace pauses the paper and pins a timestamped marker to the evidence timeline.

When the candidate clicks Submit, lockdown releases immediately, a plain-language receipt lists what was recorded, and the application exits cleanly.
