That’s the core promise of Cluely AI, one of the most controversial AI tools to emerge in 2025. Whether you’ve seen it trending on LinkedIn, heard about it from a recruiter warning candidates, or stumbled across its viral “cheat on everything” marketing campaign — Cluely has sparked a debate that cuts straight to the heart of how AI is reshaping professional life.
This guide answers everything: what Cluely AI actually is, who the Cluely founder is, how the tool works in practice, and — critically — whether Cluely is safe to use.
What Is Cluely AI?
Cluely AI is a desktop application that acts as a real-time AI assistant, designed to be invisible during screen-sharing sessions. It listens to audio through your microphone and reads your screen using Optical Character Recognition (OCR), then surfaces context-aware AI suggestions through a hidden overlay — one that doesn’t appear on shared screens in tools like Zoom or Microsoft Teams.
At launch in April 2025, Cluely was marketed as a tool to help users during:
- Job interviews — answering technical and behavioral questions in real time
- Sales calls — handling objections and suggesting talking points
- Online exams — providing answers to on-screen questions
- Meetings — summarizing discussion and surfacing relevant information
By late 2025, the company had significantly pivoted its positioning. Explicit references to “cheating on exams and interviews” were removed from its website, and Cluely rebranded toward the AI meeting assistant market — competing with tools like Otter.ai and Fireflies — offering live notes, action items, and searchable meeting history.
How Cluely Works (Step by Step)
Understanding the mechanics helps you evaluate both the utility and the risk:
- Install the desktop app — Cluely runs as a local application on your computer.
- Grant microphone and screen access — The app continuously monitors both inputs.
- Context processing — OCR reads on-screen text; speech-to-text transcribes what’s being said aloud.
- LLM query — All captured context is sent to a large language model (similar to GPT-4) to generate a response.
- Overlay display — The AI’s suggestion appears in a moveable, transparent window on your screen.
- Invisible to others — The overlay is engineered to not appear in screen recordings or shared views.
The tool also supports custom “playbooks” — you can upload PDFs like sales scripts, company wikis, or study guides so the AI pulls from your specific knowledge base rather than generic web data.
Who Is the Cluely Founder?
Understanding who built Cluely matters — because the story behind the product directly shapes how you should think about it.
Cluely was co-founded by Chungin “Roy” Lee (CEO), Neel Shanmugam (COO), and Alex Chen — all in their early twenties.
Roy Lee’s origin story is unconventional. While a student at Columbia University, Lee built a Chrome extension called Interview Coder — a tool that fed users AI-generated solutions to LeetCode coding problems during live technical interviews. He openly admitted to using it himself to land an internship at Amazon, which Amazon subsequently rescinded when they discovered the deception. Columbia suspended — and later expelled — both Lee and Shanmugam in early 2025 as a result.
Rather than stepping back, Lee leaned into the controversy. He rebranded Interview Coder into Cluely, launched it publicly on April 20, 2025, and built its entire marketing campaign around the tagline “Cheat on Everything.”
The approach was intentionally provocative. The launch video showed Lee on a date, using Cluely via smart glasses to fabricate his age and professional background in real time. The goal? Viral reach through outrage.
It worked. Cluely generated 70,000 user signups in its first week and secured $5.3 million in seed funding from Abstract Ventures and Susa Ventures on April 21, 2025. A subsequent $15 million Series A was led by Andreessen Horowitz (a16z), valuing the company at approximately $120 million by mid-2025.
Why Cluely AI Matters (Whether You Use It or Not)
Even if you never download Cluely, its existence signals something important about where AI is heading.
For professionals and job seekers: Employers and hiring managers are now actively building countermeasures. Companies like Validia have released tools like Truely specifically to detect Cluely-style overlays during interviews.
For educators and exam administrators: Academic integrity platforms like Honorlock have added Cluely-specific detection to their proctoring suites. The arms race between AI assistance and AI detection is now very real.
For the AI industry broadly: Cluely is a case study in what happens when a startup weaponizes controversy as a distribution strategy. Its trajectory — from “cheat on everything” to AI meeting notes — shows how quickly business models pivot under regulatory and reputational pressure.
Is Cluely Safe? An Honest Assessment
This is the question most people are actually searching for. The answer requires breaking “safe” into three distinct categories.
1. Is Cluely Safe for Your Career?
Probably not, if used for interviews. The most obvious risk is discovery. If an employer catches you using Cluely — or if their proctoring tool detects it — the consequence isn’t just losing that opportunity. It’s potential blacklisting in your industry.
Roy Lee himself experienced this firsthand: Amazon rescinded his offer after discovering he’d used Interview Coder. He turned that into a startup. Most job seekers won’t have that luxury.
2. Is Cluely Safe for Your Data?
This is where it gets murkier. Cluely captures continuous audio and screen data from your device and transmits it to LLM APIs for processing. Key questions you should ask before using any tool like this:
- What data is stored, and for how long?
- Is your conversation data used to train models?
- What happens in the event of a security breach?
For meetings that involve confidential client information, financial data, or proprietary business discussions, transmitting that content through a third-party AI overlay introduces real risk.
3. Is Cluely Safe as a Meeting Assistant (Its Current Use Case)?
More defensible — but still not without caveats. In its repositioned form as an AI meeting notetaker, Cluely competes in a crowded space. That said, real-world testing during Cluely’s launch period revealed meaningful performance issues: response delays ranging from 5 to 90 seconds, AI hallucinations (generating details not present in the actual conversation), and occasional generic suggestions that weren’t context-specific.
The Bottom Line: Should You Use Cluely AI?
Cluely AI is a technically interesting product built on a provocative premise. Its journey — from “cheat on everything” to AI meeting assistant — tells you something important: the original use case couldn’t survive public scrutiny, and the founders knew it.
If you’re evaluating Cluely as an AI meeting notetaker, it’s a legitimate option in a crowded space. But it comes with a trust deficit baked in by its founding story, documented performance issues at launch, and unresolved questions around data privacy.
If you’re considering using it to gain an edge in interviews or assessments — the risk to your reputation, career, and professional integrity is real and, in most cases, not worth it.
Frequently Asked Questions
What is Cluely AI used for?
Cluely AI was originally built for real-time AI assistance during job interviews, exams, and sales calls via a hidden on-screen overlay. It has since pivoted to position itself as an AI meeting assistant that provides live notes, action items, and instant answers during business calls.
Who founded Cluely?
Cluely was founded by Chungin “Roy” Lee (CEO), Neel Shanmugam (COO), and Alex Chen. Lee and Shanmugam were suspended from Columbia University after building a predecessor tool, Interview Coder, which Lee used to fake technical interview performance.
Is Cluely AI detectable?
Cluely is designed to be invisible during screen-sharing sessions. However, dedicated proctoring tools — such as Honorlock and Validia’s Truely — have developed specific detection capabilities targeting Cluely-style overlay apps. It is not reliably undetectable in all professional or academic environments.
Is Cluely AI free?
Cluely offers a free Starter plan with capped AI responses. Paid tiers (starting around $15/month) unlock unlimited AI usage and additional features. Pricing has changed since launch, so check their official website for current plans.
Is Cluely AI legal?
Using Cluely during a job interview or exam doesn’t typically violate criminal law, but it can violate the terms of service of the employer, recruiting platform, or educational institution — and may constitute fraud in certain employment contexts. Consult legal counsel if uncertain.
Has Cluely raised venture capital funding?
Yes. Cluely raised a $5.3 million seed round co-led by Abstract Ventures and Susa Ventures in April 2025, followed by a $15 million Series A led by Andreessen Horowitz, for a combined total exceeding $20 million.
