Cluely Review 2026

Last updated: May 2026

Cluely raised $15M from Andreessen Horowitz in June 2025 at a $120M valuation. Its founder Chungin "Roy" Lee was suspended from Columbia for the predecessor product, used it in an Amazon technical interview, and turned the suspension into the startup's viral "cheat on everything" marketing. Eight months later, the product has soft-pivoted toward "AI meeting assistant" framing while keeping the same GPU-level invisible overlay technology underneath. This 2026 review covers what Cluely actually does, the founder/funding story, the 2025 data breach, and where it stacks against LockedIn AI, Final Round AI, and the rest of the interview-coaching space.

Cluely was founded in 2025 in San Francisco by Chungin "Roy" Lee and Neel Shanmugam after both dropped out of Columbia. Seed: $5.3M co-led by Abstract Ventures and Susa Ventures in April 2025. Series A: $15M led by a16z partner Bryan Kim in June 2025, closed roughly ten weeks after seed. Both founders are 21 as of late 2025.

What Cluely Actually Does

Cluely is a desktop overlay app for macOS and Windows (with a 2026 iOS app and "Desktop Widget" mode). The product reads your screen via OCR, captures system audio with speech-to-text, feeds that context to an LLM, and surfaces answers in a floating overlay that sits on top of whatever else you are doing.

The technical detail that defines the product: the overlay is rendered via low-level GPU hooks (DirectX on Windows, Metal on macOS), which means it is invisible to screen-share in Zoom, Google Meet, and Microsoft Teams. Other people on the call cannot see your Cluely overlay. This is what makes Cluely useful for interview cheating, sales-call coaching, exam help, and any other context where the other party would object to AI assistance.

Use cases in 2026, in order of common usage:

• Job interviews: coding interviews (the original Interview Coder use case), behavioral interviews, system design discussions.
• Sales calls: real-time objection handling, talking points, competitive intel surfaced from CRM context.
• Meeting notetaking: post-call transcripts, summaries, action items (the soft-pivoted "meeting assistant" positioning).
• Exams and academic: still active despite the ethical pushback.

The Roy Lee / Columbia Story

You cannot review Cluely without the founder narrative. Roy Lee (full name Chungin Lee) and Neel Shanmugam built a product called Interview Coder while undergraduates at Columbia. The tool was designed for technical interviews: it watched the coding screen, generated solutions, and displayed them in the GPU-overlay window invisible to interviewers.

Roy Lee used Interview Coder in an Amazon technical interview. The story leaked. Columbia suspended both founders at the end of March 2025. Both dropped out. They incorporated as Cluely, raised $5.3M three weeks later, and turned the suspension into a viral marketing campaign with the tagline "cheat on everything."

The provocation worked. TikTok and X went into overdrive. National media covered the story (TechCrunch, Gothamist, SF Standard, Fortune). a16z came in with the $15M Series A. By mid-2025 Cluely was the most-talked-about consumer AI startup of the year. The "cheat on everything" framing was eventually softened to "AI meeting assistant" in public messaging after partnership conversations with enterprise customers required less aggressive positioning. The product underneath did not change.

Whether you find the story inspiring or distasteful is its own question. The product capability is real.

Cluely Pricing in 2026

Cluely has a free demo tier plus three paid plans. The "Pro + Undetectability" tier is the unusual one: a $75/month add-on that explicitly pays for anti-detection. No major competitor packages stealth this way.

The free tier (5 responses/day, 100-character outputs) is so restrictive it functions as a demo only. Real work requires Pro at $20/mo. The 7-day free trial on Pro gives you the actual evaluation window — use it for an interview prep cycle or a sales-call week, then decide.

How the GPU-Level Overlay Works

Most "screen-share invisible" tools achieve their invisibility by rendering to an OS-level window that the screen-share API filters out. This works until the conferencing app updates its capture logic. Cluely takes a different approach: it hooks directly into the GPU rendering pipeline (DirectX on Windows, Metal on macOS) and draws the overlay at a layer below the OS screen-capture path. Zoom, Meet, and Teams cannot capture what they cannot see.

The trade-off is platform fragility. GPU driver updates have, at least twice, broken Cluely's overlay rendering for a few days until the team shipped a fix. Some Windows configurations with mixed integrated/discrete GPUs have rendering issues. Linux is not supported.

The independent latency tests are not as flattering as Cluely's marketing claims. Cluely advertises 300ms response latency. Independent tests reported by users describe 5-10 second delays in practice, particularly during interview crunch moments. The honest read: fast enough for most conversational coaching, sometimes painfully slow during the highest-pressure moments.

The 2025 Data Breach

In mid-2025, Cluely suffered a data breach that exposed personal data, interview transcripts, and screenshots for 83,000+ users. This is non-trivial. The product captures everything on your screen, by design. A breach means everything you used Cluely for is potentially in someone else's hands. The company acknowledged the breach and made security improvements, but the structural concern remains: a tool that watches your screen during sensitive moments (interviews, sales calls, exams) is a single point of failure for that data.

If you use Cluely, assume that everything you do during a Cluely session could become public if the company is breached again. Use it accordingly.

Cluely vs LockedIn vs Sensei vs Final Round vs Verve

The interview-and-meeting assistant space has consolidated around five real competitors. Here is the head-to-head:

Quick decision framework: if you need the best stealth tech in active anti-detection environments, Cluely's GPU overlay is the strongest option, especially with the $75/mo Undetectability add-on. If you want highest claimed code-interview accuracy, LockedIn AI. If you want pre-interview practice rather than live assistance, Final Round AI. If you want communication coaching for real interviews you intend to do honestly, Verve AI.

Detection: What Companies Are Doing Back

The detection arms race has started. FabricHQ markets explicit "How to Detect Cluely" capabilities and claims 85% detection probability via behavioral signals (eye movements, response timing patterns, keystroke cadence). CoderPad flags the Cmd+Enter shortcut Cluely uses during coding sessions. Several large tech companies have updated interview policies to require candidates to share their full screen including window frame, which makes Cluely's overlay theoretically visible — though Cluely's GPU-level rendering still bypasses this in practice on most setups.

The honest read: Cluely's stealth tech is currently ahead of mainstream detection, but the gap is closing. If you are interviewing at companies that have invested in detection tooling (FAANG, finance, some unicorns), assume detection probability is real and rising.

What Users Like

• GPU-level stealth: Zoom, Meet, and Teams cannot detect the overlay natively. No major competitor matches this.
• Custom knowledge base upload: feed Cluely your sales scripts, study guides, or interview notes for context-aware responses.
• Post-call transcripts and summaries: even if you do not use Cluely live, the notetaking value is real.
• iOS app + Desktop Widget: 2026 expansions beyond the original desktop overlay.
• $20/mo Pro is competitive: cheaper than LockedIn ($55-70/mo) and Final Round ($149/mo) for unlimited use.
• 7-day free trial: enough to evaluate during an actual interview cycle or sales-call week.
• Cultural/viral brand presence: easier to discuss in hiring conversations than its no-name competitors.

Where Cluely Falls Short

• Latency is worse than advertised: 300ms claim vs 5-10 seconds in independent tests during pressure moments.
• 2025 data breach (83,000+ users): real privacy concern given the product captures everything on your screen.
• Trustpilot complaints: refund runaround, AI-only support ("Fin" denying refunds), continued billing after cancellation, annual upgrade auto-charges with no confirmation screen.
• GPU driver fragility: rendering has broken for a few days at a time on Windows/Mac driver updates.
• No Linux support: macOS/Windows/iOS only.
• Detection arms race: FabricHQ, CoderPad, and updated interview policies are closing the gap on Cluely's stealth advantage.
• Ethical pressure: using Cluely in interviews is contractually dishonest at most companies. If detected, the consequences are immediate disqualification at best, blacklisting at worst.

Who Should Use Cluely (and Who Shouldn't)

Possible legitimate uses: sales reps using Cluely on their own calls with their own customers (the customer is going to use AI tools too — symmetry). Meeting notetaking and post-call summaries. Interview prep practice (use Cluely on mock interviews to learn the rhythm, then turn it off for the real ones). Sales managers reviewing rep calls.

Skip Cluely if: you would not be comfortable explaining your Cluely usage to the other party in the conversation. The product's capabilities are powerful but the social/professional risk of detection is real and asymmetric — the upside of using Cluely in an interview is one job, the downside is being blacklisted from that company plus reputational damage if it goes public. Also skip if data privacy matters to you (see the 2025 breach). Skip if you are interviewing at companies that have invested in detection tooling.

Frequently Asked Questions

Is Cluely legal? Cluely is legal as a product. Using it during interviews or exams may violate contractual or institutional integrity policies. Using it in your own sales calls is generally fine. Using it to misrepresent your skills to an employer is fraud in some jurisdictions when material to the hiring decision.

How much does Cluely cost? Free demo (5 responses/day, 100-char cap), Pro $20/mo, Pro + Undetectability $75/mo, Enterprise $200/mo per seat. 7-day free trial on Pro.

Can Zoom or Google Meet detect Cluely? Not natively. Cluely uses GPU-level rendering (DirectX/Metal) below the OS screen-capture path. Third-party detection tools (FabricHQ, CoderPad) and updated interview policies are starting to close this gap.

Did Cluely have a data breach? Yes. In mid-2025, 83,000+ user records (personal data, interview transcripts, screenshots) were exposed. The company acknowledged it and made security improvements. The structural risk remains because Cluely captures screen content by design.

How do I cancel Cluely? Through your account settings on cluely.com. Trustpilot reviewers report friction in the cancellation flow and AI-only support that denies refunds. If you sign up for an annual plan, set a calendar reminder for the renewal date and cancel via bank chargeback as a fallback if the in-app cancellation fails.

Cluely vs LockedIn AI? LockedIn claims higher code-interview accuracy (92%) and bills itself as cloud-only military-grade stealth. Cluely's GPU-level desktop stealth is more sophisticated but Cluely's responses are slower than LockedIn's in independent tests.

Cluely vs Final Round AI? Final Round AI ($149/mo) is strongest for pre-interview practice and mock interviews; weakest on live latency. Cluely is the opposite: live-first, less mock-interview depth. If you have a month before the interview, Final Round. If you have a week, Cluely.

Who founded Cluely? Chungin "Roy" Lee and Neel Shanmugam, both 21, dropped out of Columbia after being suspended over the predecessor product Interview Coder. Headquartered in San Francisco. Funded by Abstract Ventures, Susa Ventures, and Andreessen Horowitz at a ~$120M valuation as of June 2025.

Our Verdict

Cluely is the most technically sophisticated interview/sales-call AI assistant on the market in 2026. The GPU-level overlay genuinely defeats Zoom, Meet, and Teams screen-capture in ways its competitors do not. The viral founder story, a16z backing, and continued product expansion (iOS, Desktop Widget, meeting assistant features) confirm the demand.

The product is also the most ethically loaded tool in any 2026 SaaS category. Using Cluely in interviews is contractually dishonest at most companies and the consequences of detection are asymmetric and severe. The 2025 data breach is a real privacy concern that any user should weigh. The Trustpilot complaints about billing and refunds are documented.

If you are buying Cluely for legitimate sales-call coaching, meeting notetaking, or interview prep practice, $20/mo Pro is a reasonable spend. If you are buying it to cheat in an interview, weigh the upside (one job offer) against the downside (detection, disqualification, blacklisting, reputational damage). The detection arms race is real and tightening.
