- What it is
- A transparent heads-up display that streams AI-generated answers directly to a candidate's local screen while remaining invisible to screen-sharing, webcam, and most proctoring software.
- Why it matters
- Invisible overlays are the dominant AI cheating vector in 2025–2026, and they defeat lockdown browsers and behavioral proctoring by design — nothing about the captured video stream reveals their presence.
- How Aiseptor addresses it
- Aiseptor operates below the application layer, so overlay tools and their traffic patterns cannot hide from its enforcement — the exam device is constrained to the authorized network path regardless of what renders on the candidate's screen.
Canonical definition
An invisible AI overlay is a desktop application that uses low-level graphics hooks to render text on top of other windows while marking its own surface as excluded from screen-capture APIs. The candidate sees AI-generated answers, code, or prompts in a heads-up display aligned to the interview question. A remote interviewer, proctor, or screen-share viewer sees only the underlying editor — the overlay is absent from the captured video stream. Audio variants extend this pattern: the candidate's microphone is piped to a local speech-to-text pipeline that feeds a language model, and the answer is shown on the same invisible surface. Because the overlay produces no artifacts in a standard screen recording, detection strategies built around what the interviewer sees are architecturally defeated. The category includes both commercial products and the many open-source forks that ship with the same primitives.
