Is Cluely Safe and Undetectable? A Skeptical Look
People search 'is Cluely detectable' for two different reasons: whether the overlay shows up in a screen share, and whether using it carries risks beyond that. Here's how to think through both without trusting anyone's marketing, including ours.
Disclosure: we make InterviewPilot, a competing Windows product. We'll keep this about how to evaluate the claim, because the same questions apply to every tool, including ours.
"Undetectable" is two claims
- Technically invisible: it doesn't show up in screen shares, recordings or screenshots.
- Behaviorally invisible: nobody can tell you're getting help.
Vendors usually prove the first and imply the second. Only the first is something software can do.
How technical invisibility works
On Windows, SetWindowDisplayAffinity with WDA_EXCLUDEFROMCAPTURE tells the compositor to leave a window out of capture. Zoom, Teams and Meet capture through standard APIs that honor it. We explain the mechanism in How Windows screen capture exclusion works. macOS has an equivalent mechanism with different caveats.
What it doesn't cover:
- A physical camera pointing at you or your monitor
- Behavior: reading eye movement, response delay, unnatural phrasing
- Lockdown or proctoring clients that inspect the system, as in secure-browser tests
- Capture paths that don't honor the flag (some hardware capture setups, remote-control tools)
The tier question
Check what the plan you're paying for includes. At the time of our last comparison, Cluely's pricing page associated its full screen-share invisibility with its highest tier rather than its base plan. Pricing changes often, so read the current page, and see our Cluely comparison for how we checked it.
A test you should run regardless of vendor
- Start a call with yourself on a second device or account.
- Share your entire screen, not a single window.
- Open the overlay and trigger an answer.
- On the receiving side, look: is the overlay absent? Is there a taskbar entry, a flicker, a cursor oddity?
- Record the call locally and play it back.
If a tool fails this test on your machine, no marketing claim matters.
Safety is a separate question
- What does the app access (microphone, system audio, screen)?
- Where do transcripts and screen captures go, and for how long?
- Can you delete your data?
- Is the vendor identifiable, with a real company, a policy and support?
Beware of name-alikes. Several unrelated products share similar names across the category.
And then there's the rules
Whether it's allowed is decided by the company interviewing you. If they prohibit outside help, the risk is your offer and your reputation, not a pixel. Weigh that honestly.
Want this on your screen during the real interview?
InterviewPilot listens to the interviewer, reads the problem off your screen, and streams a structured answer to an overlay that Zoom, Meet and Teams screen shares can’t see.
Questions to ask before installing any interview tool
| Area | Question | Why it matters |
|---|---|---|
| Permissions | Does it need screen recording, microphone, accessibility? | Each is a sensitive capability |
| Data flow | Is audio or screen content sent to servers? To which providers? | Interview content can include confidential company info |
| Retention | How long are transcripts stored? Can you delete them? | Check the privacy policy, not the landing page |
| Identity | Who runs the company? Is there a real support channel? | Name-alike products are common in this category |
| Refunds | What happens if it fails during a real interview? | A refund window limits the loss |
| Updates | How often does it ship? | Meeting apps change capture behaviour over time |
How capture behaviour can change
Meeting software updates frequently. A mechanism that works today can behave differently after an update to Zoom, Teams, Meet or Windows itself. Two practical rules follow:
- Test on the exact setup you'll use, including the meeting app version, within a day of the interview.
- Re-test after any update to Windows or the meeting software.
Why behaviour beats pixels
Even a perfectly excluded window leaves your behaviour. Interviewers report spotting:
- Eyes tracking text in a consistent spot
- Answers that begin after an unnatural delay
- Over-polished phrasing that doesn't match the rest of the conversation
- Inability to extend or justify an answer
If you use any assistant, treat its output as notes to react to, not a script to read. See how to use AI during a live interview.
About this comparison
We make a competing product, so we've kept this post about method rather than verdicts. When we mention a competitor's plans, the claim comes from its public pricing page on the date shown on our comparison page, and plans change. If you spot something out of date, tell us and we'll correct it.
