Detection · Hidden AI assistants

Detect hidden AI assistants in remote interviews.

A subscription industry of AI tools now feeds candidates expert answers on an overlay only they can see — invisible to Zoom, Teams, and Meet. Capifiq surfaces that assistance as it happens, names it on the interview timeline, and seals it as evidence — even for a tool it has never seen before.

The threat

Answers, delivered on an invisible overlay.

Hidden AI assistants are desktop or web tools built for one purpose: to help a candidate cheat a live interview without anyone noticing. They listen to the interviewer through the machine's own audio, generate an expert-level answer in a second or two, and display it on a transparent overlay the candidate reads from — like a teleprompter only they can see.

It is a paid, fast-growing category. Many tools market themselves, in their own words, as "undetectable" on Zoom, Teams, and Meet. Each new entrant widens the surface a hiring team has to defend.

Tools in this category

  • Cluely — invisible desktop overlay
  • Interview Coder — coding-focused, claims zero detections
  • Leetcode Wizard — OCR answer overlay
  • Final Round AI — desktop "stealth" copilot
  • LockedIn AI — desktop app plus browser extension
  • …and the next tool shipped tomorrow

The blind spot

Why screen sharing and proctoring miss them.

These tools are engineered specifically to evade the defenses most teams already run.

Invisible to screen share

The overlay renders outside the surface the operating system shares, so it never enters the stream the interviewer sees.

Native, not in the browser

They are native desktop applications. Browser proctoring lives inside the tab and has no window into them.

Renamed and rebuilt

A denylist scanner only knows what it has catalogued. A renamed executable or a brand-new tool simply isn't on the list yet.

What Capifiq surfaces

  • That an unauthorized assistant is active during the session
  • The detected category and the event timestamp
  • Coverage that isn't limited to a named list of products
  • Cryptographically hashed, sealed evidence for later review

The coverage

Caught by what it does, not what it's called.

Capifiq verifies the interview environment rather than matching a catalog of product names. So a hidden AI assistant is surfaced by the fact that it is running and assisting — not by whether we have seen that exact product before.

Rename the executable, fork it on GitHub, or build a private one: the coverage holds. The finding lands on the interview timeline in real time and is sealed into the report as deterministic evidence — not a probability score.

The full picture

On-device is only half of it.

Capifiq detects any unauthorized assistance running on the candidate's device — hidden overlays are one of the common vectors, not a fixed list. And for help that never touches the device, interviewing methodology deters what no software can see.

Questions

Common questions.

Does Capifiq detect tools like Cluely or Interview Coder?
Yes — and it is not limited to a named list. Because Capifiq verifies the interview environment rather than matching known product names, it surfaces the activity of a hidden AI assistant even when the specific tool is renamed, privately built, or brand new.
How can a hidden AI assistant be invisible on a screen share?
These tools render their overlay outside the surface the operating system shares, so it never enters the stream the interviewer sees. That is exactly why screen sharing and browser proctoring miss them — and why a companion agent is needed to catch them.
Does Capifiq read what is on the candidate's screen?
Capifiq surfaces that an unauthorized assistant is active and records it as evidence — a factual, timestamped finding, not a probability score. See the Security & Trust page for exactly what is collected.
What happens when a brand-new tool appears?
Coverage does not depend on the tool already being catalogued, so a newly shipped or privately built assistant is in scope from day one. That is the core of why Capifiq is a different category.

Catch the overlay your screen share can't.

Run Capifiq alongside the Zoom, Teams, or Meet calls you already do, and see what it surfaces.
