Quick answer: Cluely is a real, funded company with a genuine working product, so in the narrow sense of “does it exist and function,” it is legitimate. But legitimate does not mean trustworthy or safe to use. Cluely’s own founder has a documented history of academic dishonesty and inflating company revenue figures, its “undetectable” claim is increasingly contested, and using it in interviews, exams, or professional settings you were not authorised to use it in carries real legal, ethical, and career risk.
Cluely markets itself directly as a tool to “cheat on everything,” an AI overlay that listens to your calls and reads your screen to feed you real-time answers during interviews, exams, and sales calls, invisibly, according to its own claims. Before you trust that claim, or the company behind it, here is what the evidence actually shows.
What Is Cluely?
Cluely is a desktop application that runs during video calls, listening through your microphone and reading your screen to generate real-time suggested responses, displayed as an overlay its makers claim is invisible to whoever you are speaking with, including on screen-sharing platforms like Zoom and Microsoft Teams. It launched publicly in March 2025 and has two core modes: a real-time overlay during a live call, and a preparation mode that generates likely questions in advance from a pasted job description.
Is Cluely a Real Company? Yes, But That’s Not the Same as Trustworthy
Cluely is a genuine, operating company with a real product that a meaningful number of people have tested and reviewed. It has an official website, funding, enterprise documentation including a Data Processing Agreement and a Subprocessors page. In the narrow sense of existing and functioning as described at least some of the time, it is legitimate.
But “legit” and “trustworthy” are separate questions here, and the second one is where the serious problems begin.
The Founder Controversy Is Not a Minor Detail
Cluely was created by Chungin “Roy” Lee, a former Columbia University student who was placed on disciplinary probation after openly building and promoting tools designed to cheat on remote job interviews and exams while a student there. This is not incidental background, it is the direct origin story the company has leaned into as marketing.
More seriously, in March 2026 Lee was reported to have inflated Cluely’s annual recurring revenue figures publicly. Separately, a compliance certification platform Cluely had used to demonstrate its security credentials was reported to have been expelled from Y Combinator over allegations of fabricating audit evidence. Taken together, this is a documented pattern of dishonesty at the leadership level of a company whose entire product pitch rests on convincing you it can help you deceive people undetected.
Does the “Undetectable” Claim Actually Hold Up?
This is the central marketing promise, and it is increasingly contested. Independent reviewers report average response latency of 3 to 5 seconds, too slow for the rapid-fire pace of many technical interview rounds, meaning the tool’s answers can visibly lag behind the conversation in a way that is itself a detection risk. Detection technology and platform policies have also evolved through 2026 specifically in response to tools like Cluely, meaning any “undetectable” claim made in 2025 is already outdated as a current guarantee.
One independent review that tested Cluely in a mock Business Insider interview found the tool actively invented work experience the user never had and misread skills listed on their own LinkedIn profile, a serious accuracy failure precisely in the high-stakes situation it is marketed for.
The Real Risks of Using It
Beyond whether it works technically, using Cluely in a context you were not authorised to use AI assistance in carries consequences worth understanding clearly:
- Academic and professional integrity violations. Using undisclosed AI assistance in an exam or interview where it is prohibited is a genuine integrity breach, with consequences ranging from a rescinded job offer to academic expulsion, the same outcome its own founder faced.
- Recording consent laws. Recording calls without the other party’s knowledge or consent is illegal in many jurisdictions, including two-party consent states in the US and equivalent laws elsewhere. Cluely’s core function depends on listening to conversations the other participant has not agreed to have processed by AI.
- Reputational and career damage if discovered. Being caught using an undisclosed real-time AI tool in a professional interview or negotiation can end that opportunity immediately and follow you if discovered later.
- A privacy policy is not the same as informed consent from the other person on the call. Cluely’s enterprise documentation addresses data handling on Cluely’s end, but does not resolve the separate ethical question of the other participant’s consent to being covertly assisted by AI.
Cluely Pricing
Cluely offers a Pro plan priced around 20 US dollars a month for unlimited access to its real-time assistance features. Reviewers have separately flagged billing practices as a point of friction, worth checking current terms carefully before subscribing.
Common Questions About Cluely
Is Cluely legit?
It is a real, operating company with a functioning product. That is different from being trustworthy: its founder has a documented history of dishonesty, and its central “undetectable” marketing claim is increasingly contested.
Is Cluely safe to use in a job interview?
Using it where AI assistance is not disclosed or permitted carries real risk, including a rescinded offer if discovered, and response latency issues that can make its use more noticeable than advertised.
Is recording a call with Cluely legal?
It depends on your jurisdiction. Many places require consent from all parties on a call before recording or processing that conversation, which Cluely’s core function does not obtain from the other participant.
Is Cluely actually undetectable?
This claim is increasingly contested. Detection methods and platform policies have evolved specifically in response to tools like Cluely, and independent testing has found noticeable latency and accuracy issues that undermine the undetectable claim in practice.
Who founded Cluely?
Chungin “Roy” Lee, a former Columbia University student placed on disciplinary probation for building similar cheating tools while a student, later reported to have inflated the company’s revenue figures publicly.
The Bottom Line
Cluely is a real product from a real company, so it clears the lowest bar for “legit.” But its founder’s documented dishonesty, the contested reality behind its central undetectability claim, and the genuine legal and career risk of using it in situations you are not authorised to use AI assistance in, make this a case where existing and being trustworthy are two very different questions. If you are considering it for a genuinely permitted use case, verify current platform policies first and understand that “undetectable” is a marketing claim under active challenge, not a guarantee.
