Every product in this category says it's undetectable. Cluely calls itself "#1 Undetectable AI for Meetings." Interview Coder says "The No. 1 Undetectable AI For Interviews." Parakeet says "100% Undetectable." InterviewMan says it "has never been detected."
They can't all be first, and none of those sentences tells you anything you can act on.
What this list actually ranks — read this first
We have not tested these tools against live proctoring software. Nobody publishing a list like this has. Doing it properly would mean running each product against current builds of Zoom, Teams, Meet, HackerRank, Codility and a proctoring suite, repeatedly, and publishing the method. That study doesn't exist, and any ranking claiming to measure real-world stealth is inventing one.
So this ranks something we can actually assess: how specifically each vendor documents the mechanism.
That distinction matters more than it sounds. There are two kinds of claim in this market:
- Outcome claims — "nothing the interviewer can see," "no visible overlay." True, probably. Unfalsifiable, and silent about what happens if someone asks you to open Activity Monitor.
- Mechanism claims — "absent from the dock, the menu bar and Activity Monitor, running under this process name." Specific enough that you can verify it yourself in thirty seconds.
A vendor willing to make the second kind is exposing itself to being checked. That's the signal. It isn't proof of stealth, and this post doesn't claim it is — but between a checkable claim and an unfalsifiable one, only one of them can be wrong in public.
We make Velin AI. It ranks first here on documentation specificity, which is a criterion that happens to favour a product built to be described that way. Weigh that accordingly, and check the claims yourself — that's rather the point.
The ranking
1. Velin AI — documents the mechanism, layer by layer
The most specific documentation in the category, and all of it checkable on your own machine.
Hidden at the operating system level rather than by drawing a window that screen capture is asked to skip. Named surfaces: absent from the dock, the menu bar and Activity Monitor. Runs under the process name V Module, which reads like a system utility — so a process list shows nothing that invites a question. Click-through, and never becomes the active window, so there's no focus change or tab switch.
The part nothing else here offers: mouse gesture control. Every other tool on this list is driven by keyboard input, and a keystroke is an event a platform can log. Velin can be driven by gestures, undetectable clicks or keyboard, so in a keyboard-monitored environment you can leave that surface untouched entirely.
What it doesn't claim: that any specific proctoring product has been beaten, or that detection is impossible. There's no "never been detected" line, because that isn't knowable.
2. Interview Coder 2.0 — specific, with an absolute claim attached
Documents concretely: invisible in dock and Activity Monitor, click-through interface, invisible to screen sharing and system tray, and "30+ undetectability features... tested every single day against every single interview software." Names the platforms it covers, including HackerRank, CoderPad and Codility.
That's real specificity and it's why this places second.
Where it loses ground: the claim of "zero documented cases of users being detected or flagged when using this tool properly during technical interviews" does a lot of work in the phrase "when using this tool properly" — it's structured so any detection becomes user error. And control is keyboard-only, so the input surface stays live.
Also worth knowing before you buy on this ranking: $299/month or $799 lifetime.
3. InterviewMan — specific, but part of it needs a second device
Strong documentation: invisible in dock and Activity Monitor, screen-recording proof, "30+ advanced undetectability features" including browser-detection prevention and WebRTC blocking. Broadest named platform coverage of anyone here.
What moves it to third is the architecture rather than the documentation. Among the stated features is that it "beats anti-cheating tools via two-device stealth mode" — so part of the stealth depends on a second device being present rather than on the machine you're interviewing on. That's a workable approach when you control the room. It's more moving parts, and more to explain if someone asks about your desk.
They also state the product "has never been detected." No software can know that. Treat it the way you'd treat any absolute claim, from anyone.
4. Interview Solver — the most honest boundary in the category
Fourth on breadth, first on candour. Their site states invisibility applies to "Zoom (≤6.16) and any browser-based screen recording software", plus undetectable global hotkeys and invisibility in Activity Monitor.
Almost nobody publishes a version boundary. It's the most useful sentence any vendor in this category has written, because it tells you exactly when the guarantee stops applying.
Why it's fourth rather than higher: a guarantee pinned to Zoom 6.16 or below has an expiry date, and Zoom updates on its own schedule. If your interviewer has a newer build, you're outside what the vendor has claimed. Narrow scope too — LeetCode and system design only.
Not ranked, and why
Cluely documents undetectability as "completely hidden to meeting screen sharing software" — an outcome claim, and one that only applies on the $149.99/month tier. The $19.99 plan most people quote isn't hidden at all.
Final Round AI describes it as "no pop ups no visible interface and nothing the interviewer can see." Outcome again, with no mention of dock, Activity Monitor or process naming.
LockedIn AI says "the interviewer sees only you and your normal screen share. There are no LockedIn AI overlays, no helper presence, and no UI elements visible." Same category of claim.
Parakeet AI claims "Invisible in Dock" and "Invisible in Task Manager" — which is mechanism language, and would place it higher — except it's browser-first, and those claims describe its desktop app rather than the tab most people use. A browser tab is enumerable by a browser extension, which is where proctoring software lives.
None of that means these tools get caught. It means their vendors haven't told you enough to judge.
How to check any of them yourself
Useful whichever tool you end up with, and it takes a minute:
- Open Activity Monitor (macOS) or Task Manager (Windows) with the tool running. Search its name. Then search for anything you don't recognise — the process may be named something else entirely.
- Start a Zoom meeting with yourself and share your screen. Record it. Play the recording back and look.
- Check the dock, the menu bar and the system tray.
- Alt-tab through your windows. If the tool appears in the switcher, it can be found.
- Do it again after every update — yours and the platform's. This is the step everyone skips, and it's the one that matters when a vendor pins a claim to a version number.
If a tool fails any of these on your own machine, no marketing page changes that.
The honest summary
Ranking real-world undetectability isn't possible from the outside, and you should be suspicious of any list that claims to. What you can do is prefer vendors who tell you how it works over vendors who tell you it works, and then verify on your own machine before it matters.
On that criterion the order is Velin AI, Interview Coder, InterviewMan, Interview Solver — with Interview Solver deserving credit for publishing the limit that the other three don't.
Going deeper: the invisibility breakdown covers Velin's layers, Velin AI vs Interview Coder is the closest matchup here, and Velin AI vs InterviewMan covers the two-device question.
All claims quoted from each vendor's own site on 12 August 2026. No tool in this list was tested against live proctoring software; this ranks published documentation, not measured performance.
