Cluely is an AI tool built for cheating in live conversations, and it has raised $5.3 million. The startup is founded by Chungin "Roy" Lee, who was suspended from Columbia. I put the app through a mock interview to see if it could help me land a job. A Ivy Leaguer just released an AI app to feed live answers to users. I put it to the test to see if AI could interview as well as I did.Chungin "Roy" Lee — the Columbia student who went viral for creating an AI tool to "cheat" on job interviews — was suspended in March for posting content from a disciplinary hearing, the university said.His new app, Cluely, helps users by analyzing what's on their screens, hearing audio, and suggesting answers to questions, all without detection from the other side. In a LinkedIn post, Lee said Cluely is a "cheating tool for literally everything."Lee said on Monday that San Francisco-based Cluely has raised $5.3 million, backed by Abstract Ventures and Susa Ventures.Speaking to Business Insider on Wednesday night, Lee said that Cluely has gained about 70,000 users since its launch on Sunday."It is pretty crazy. And this is just a lot more than we expected," he said.Lee said the concept of "cheating" needs to be rethought in the AI era."Using AI is just inevitable and something that we should just all embrace," he said.I put Cluely to the test, and I saw promise — but also huge privacy concerns.First impressionsI tested Cluely on Tuesday morning and paid $20 for the Pro version — a monthly subscription — since the free tier doesn't offer much.The interface is slick and minimal: a thin bar on the top of my screen. With one keyboard shortcut, Cluely scans my screen, then generates answers. I could also speak to it through my mic.It only works with what's already on my screen — it doesn't crawl the internet like ChatGPT.It also reads everything. I kept my Signal group chats closed.That's what makes it powerful — and also kind of terrifying.Lee told BI that Cluely doesn't save any data, and if it does, it's "heavily censored.""If there's something that you don't want to be seen, then you shouldn't use the tool, and it shouldn't be up while you're on sensitive information," Lee said.I deleted it right after writing this story. Flopping my mock interviewCluely's killer pitch is real-time assistance.I let it scan my LinkedIn profile and kept it open while my editor put me through a mock interview with the same questions I answered to land this job.First up: What is my media consumption like? Could I share what I like to read or watch? What keeps me interested and busy?The app starts "thinking." Five seconds later, it gave me a summary of the question, not an answer.My editor tried again, more succinctly: "What media outlets do you read?"This time, Cluely came through:"I enjoy staying up to date with a mix of international and local news — typically from outlets like the New York Times, BBC, and CNA. I love longform journalism from The Atlantic and Wired, especially on tech and social issues. I also listen to 'The Daily' and 'Planet Money' during my commute."Not bad, though I don't listen to podcasts on my way to work.My editor asked me to talk about a difficult story I've worked on. 10 seconds of awkward silence later, Cluely offered: "One difficult story I worked on was about the impact of layoffs in the tech industry."I never wrote that story.The second hallucination came when the app said I had a "working knowledge of Malay." My editor congratulated me on my surprising — including to me — third language skill. It completely missed the elementary Korean listed on my LinkedIn.When my editor asked if I had questions for her, Cluely suggested a few basics: What do you enjoy most about working here? What's the team culture like? What does success look like in this role?Not worth the $20 — yet.Cluely's biggest flaw is speed. A five to 10-second delay feels like forever in a live interview.The answers were also too generic, occasionally wrong, and not tailored enough to me.It did generate decent answers to common questions. When I read them aloud, my editor said the biggest clue I had help was the delay, not the substance. She also said my real answers were better than Cluely's.Lee told BI that Cluely is in "a really raw state.""Our servers are super overloaded, so there's a lot of latency," he said.But there have been "significant performance updates" since the app went out on Sunday, he added."We've upgraded all our servers, we've optimized the algorithms, and right now it should be about three times faster, which makes it much more usable in conversations."Lee said hallucinations will "exist insofar as the base models that we use allow for them.""The day that the models get better is the day that our product will get better," he added.There's definitely potential. If Cluely got faster, smarter, and could pull info from beyond just my screen, it could become a game-changing AI assistant. If I were hiring, I might think twice about conducting remote interviews because of these sorts of apps.But between the privacy risks, laggy performance, and random hallucinations, I'm keeping it off my computer.
