Cluely AI Review 2026: Does “Cheat on Everything” Work?

Author: Aisha Khan | Updated: February 2026 | Read Time: 11 minutes

Quick Summary: Cluely AI is a real-time desktop assistant that listens to meetings and displays an invisible AI overlay during live calls. It genuinely works for proactive context suggestions during meetings — but comes with a documented 2025 data breach, real latency problems, and ethical questions that anyone considering it should understand before subscribing. Pricing: Free (5 responses/day), Pro ($20/month), Pro + Undetectability ($75/month), Enterprise ($200/month).

Few AI tools in 2025 generated as much debate as Cluely. The “cheat on everything” marketing was deliberate provocation — founder Roy Lee built it to be controversial, and it worked. But underneath the viral marketing is an actual product that real people are using for real meetings, interviews, and sales calls.

This review cuts through the hype in both directions. It covers what the tool genuinely does well, where it falls short based on documented user testing, what the real privacy risks are, and who should — and shouldn’t — use it.

What Is Cluely AI?

Cluely is a desktop application that runs an invisible AI overlay during live video calls. It listens to microphone audio, reads on-screen content using OCR, and displays real-time suggestions in a floating panel that is only visible to the user — not to other meeting participants.

The tool works across Zoom, Google Meet, and Microsoft Teams without joining calls as a participant. When someone asks a question during an interview or sales call, Cluely processes the audio and displays suggested responses, talking points, or code snippets within seconds. Users can also upload custom documents — PDFs, sales playbooks, company wikis — and Cluely references those when generating suggestions.

Cluely was founded by Roy Lee, who initially built a version called Interview Coder while at Columbia University. Columbia later expelled him after discovering the tool had been used to fake technical interviews. Rather than backing down, Lee rebranded the product as Cluely, raised $5.3 million from investors including Andreessen Horowitz, and publicly leaned into the controversy. The company has since raised over $20 million in total funding and is valued at approximately $120 million.

The platform now positions itself primarily as a meeting assistant and real-time sales coaching tool, though its interview-assistance use case remains prominent in its marketing. For a quick specs overview, the Cluely AI tool listing covers the platform’s core features at a glance.

Hands-On Testing: What Cluely Actually Does in Practice

Testing Cluely across a real meeting workflow reveals both its strongest capability and its most significant weakness.

What it genuinely does well: The proactive context feature is the most impressive aspect of the platform. During a live call, when a specific product or topic comes up in conversation, Cluely automatically surfaces relevant questions to explore or context to reference — without the user having to type anything. In a sales scenario, this means the tool can flag a competitor name mid-call and prompt the user to ask follow-up questions. This is meaningfully different from just having ChatGPT open in another tab.

The latency problem is real: Multiple independent tests have documented a 5–10 second delay between when a question is asked and when Cluely displays a usable suggestion. Business Insider’s hands-on test confirmed this delay in interview scenarios. In a natural conversation, a 5–10 second pause while waiting for the overlay to update is noticeable and awkward — it can actually make the user appear less competent rather than more prepared.

Response quality varies by model: The free tier uses lower-end models (GPT-4.1, GPT o4-mini) and limits responses to 100 characters, which makes them too brief to be genuinely useful. The Pro tier ($20/month) unlocks GPT-5 and Claude 4 access, and the response quality improves substantially. Most honest assessments of Cluely conclude that the free version is a demo, not a usable tool.

The keyboard shortcut conflict: One specific frustration that consistent users report is that Cluely’s CMD+Enter shortcut — used to open the AI chatbox — conflicts with the same shortcut used by Gmail, Superhuman, and other common tools to send emails. There is currently no way to remap this. If Cluely is running in the background during non-meeting work, it creates real workflow interruptions.

Where it works best: Sales call preparation, handling product objections with a custom playbook loaded, and quickly referencing technical documentation during a developer call. These are the scenarios where the proactive context feature adds value that a static document or separate ChatGPT window doesn’t easily replicate.

Cluely AI Key Features

Invisible Overlay

The overlay renders through a low-level graphics layer designed to be excluded from screen recording and shared screen captures. When a user shares their screen during a Zoom call, participants see the presentation — not the Cluely panel. The company calls this “undetectable,” though behavioral cues (eye movement, response latency, reading patterns) can still reveal AI assistance to observant participants. The tool’s own Terms of Service include an “Important Notice” requiring users to inform other call participants that recording is active and obtain consent — which directly contradicts the “undetectable” marketing claim.

Custom Playbooks and Knowledge Base

Users can upload PDFs, product documentation, flashcards, or company wikis. Cluely references this content when generating real-time suggestions. Pre-built playbooks are available for common scenarios including technical interviews, enterprise SaaS demos, VC pitch preparation, and customer success calls. The Enterprise tier adds a RAG (Retrieval-Augmented Generation) knowledge base that enables more sophisticated document-referenced responses.

Real-Time Transcription

Cluely transcribes everything said during a call in real time, which feeds context into the AI suggestion engine. After the call ends, users receive a structured meeting summary with detected action items. The post-call summary feature is functional and accurate — multiple testers note it correctly identifies tasks from casual phrasing like “I’ll send that over next week.”

Searchable Meeting Archive

Every meeting is saved to a searchable dashboard. Users can query past conversations to retrieve specific quotes, decisions, or commitments without rewatching recordings.

Voice and Platform Support

Cluely works on Windows and macOS (Linux in developer preview). It integrates with Zoom, Google Meet, Microsoft Teams, Amazon Chime, and Cisco WebEx. It does not currently support non-English meetings, which is a meaningful limitation for international teams.

The free tier functions as a demo, not a working tool — 5 responses per day with a 100-character output limit is not enough for any meaningful use. The Pro plan at $20/month is where the product becomes genuinely usable, but it still carries all the ethical and privacy concerns described below. The Pro + Undetectability tier at $75/month is transparently targeting users who want to use the tool covertly — a meaningful ethical consideration for anyone evaluating it.

The Controversy: What Everyone Considering Cluely Needs to Know

Cluely’s marketing strategy is built around controversy, and understanding the real concerns behind it matters for anyone deciding whether to use the tool.

The 2025 Data Breach

In mid-2025, Cluely suffered a data breach that exposed the personal information, meeting transcripts, and screen captures of over 83,000 users. According to security researchers, the breach did not require sophisticated exploitation — hackers accessed the system because Cluely’s developers had left an admin password file in a public GitHub repository. Combined with weak GraphQL protections and client-side paywall checks, the exposure was significant.

For a tool that records sensitive professional conversations — sales calls, job interviews, internal strategy meetings — this security failure is not a minor footnote. Anyone considering Cluely for business use should factor this incident into their evaluation. The Enterprise plan claims no data training on conversations, but the 2025 breach demonstrates that security commitments are only as strong as their implementation.

The Legal Gray Area

Cluely’s privacy policy explicitly states that users must inform other call participants that recording is active and obtain their consent. This is legally required under privacy laws in many jurisdictions, including GDPR in Europe and two-party consent laws in several US states. The “undetectable” marketing actively encourages the opposite behavior — creating a situation where the tool itself pushes users toward potential legal violations while making users legally responsible if issues arise.

The Ethics Question

The core ethical question is straightforward: should other participants in a professional conversation know that AI is actively coaching one party? Reasonable people disagree on this. Some argue it is no different from having notes prepared in advance. Others argue it misrepresents the actual knowledge and capability of the person using it. The specific context matters significantly — using Cluely to recall product specs during a sales call is different from using it to fake technical expertise during a job interview.

The interview cheating use case deserves direct acknowledgment: using Cluely to pass a technical interview for a role that requires the knowledge being tested creates a professional situation where the hired person may lack the capabilities the employer reasonably expects. This has downstream consequences beyond just the individual user.

Who Is Cluely AI Actually For?

Based on real testing and user feedback, Cluely delivers genuine value in specific contexts and is a poor fit in others.

Where it makes sense: Sales teams handling high-volume product calls where consistent messaging and fast objection handling matter. The custom playbook feature, combined with proactive context suggestions, provides real value for reps who need to reference technical specs or pricing details quickly without breaking conversation flow.

Professionals who routinely reference complex documentation during client calls — consultants, account managers, technical support teams — can benefit from the searchable knowledge base and real-time document referencing.

Where it is a poor fit: Job seekers using it to pass technical interviews for roles where the tested skills are actually required for day-to-day work. The latency problem (5–10 second delays) also makes it genuinely counterproductive in fast-paced interview scenarios. For legitimate AI-assisted interview preparation instead, the HireVue guide covers tools and strategies that work transparently with employers rather than against them.

Any context where the user’s organization or the other party’s organization has policies against AI assistance during meetings or assessments. Given the 2025 data breach, enterprise teams with strict data governance requirements should evaluate the security track record carefully before deployment.

How to Get Started With Cluely

1. Download the desktop app from cluely.com for Windows or macOS.
2. Create an account — no credit card required for the free tier.
3. Install the app and grant microphone and screen permissions during setup.
4. Join any Zoom, Google Meet, or Teams call and activate Cluely using the CMD+\ hotkey.
5. The floating overlay appears on your screen outside the area being shared.
6. Optional: Upload custom documents or select a pre-built playbook before high-stakes calls for better-tailored suggestions.

Note on setup: The keyboard shortcut conflicts with common tools like Gmail and Superhuman. If leaving Cluely running outside of meetings, expect regular accidental triggers of the chatbox.

Fireflies and Otter.ai focus on transcription and post-call summaries — they do not provide real-time suggestions during live calls. If real-time coaching during a call is the core need, Cluely is one of very few tools that does this. If the primary need is accurate meeting documentation with good CRM integration and no ethical complications, Fireflies is a stronger choice. tl;dv is worth considering for teams who specifically want post-call coaching and analysis with a cleaner privacy record.

Frequently Asked Questions

Is Cluely AI free?

Yes, there is a free Starter plan that includes 5 AI responses per day and unlimited meeting note-taking. The output on the free tier is limited to 100 characters per response, which makes it genuinely too limited for most use cases. The Pro plan at $20/month is where it becomes fully functional.

Is Cluely AI detectable?

The overlay is designed to be excluded from screen recording software, and the company calls it “undetectable.” However, the tool’s own Terms of Service require users to disclose that recording is active to other participants. Behavioral cues like eye movement and response patterns can still reveal AI assistance to attentive observers.

What happened with the Cluely data breach?

In mid-2025, a breach exposed data from over 83,000 users including meeting transcripts and screen captures. The cause was a developer oversight — an admin password was left in a public GitHub repository. This is documented and significant for anyone considering the platform for sensitive professional conversations.

Does Cluely work on mobile?

No. Cluely is a desktop application available for Windows and macOS. There is no official mobile app.

Can Cluely be used for job interviews?

It can be used, but whether it should be depends on context. Using it to cheat on technical assessments for roles that require the tested knowledge raises serious professional ethics concerns and may violate employer policies. The documented 5–10 second response latency also makes it less effective in fast-paced interview scenarios than its marketing suggests.

Who founded Cluely?

Roy Lee co-founded Cluely after being expelled from Columbia University for using a predecessor tool to fake technical interviews. The company has raised over $20 million in total funding including investment from Andreessen Horowitz.

The Bottom Line

Cluely is a real tool with a genuine technical capability — real-time AI context during live calls — that most competitors do not offer. The proactive suggestion feature during sales calls and the custom playbook system provide actual value in specific professional contexts.

The limitations are equally real. A 5–10 second latency in responses undermines the core use case in fast conversational scenarios. The 2025 data breach represents a documented security failure that enterprise users should take seriously. The legal gray area around consent creates genuine risk for users in jurisdictions with two-party consent requirements.

At $20/month for the Pro plan, Cluely is not expensive by software standards. Whether it is worth that price depends almost entirely on context — for sales teams handling high-volume product calls with approved use policies, the proactive context feature offers real value. For interview assistance, the combination of ethical concerns, legal exposure, and documented latency makes it a tool whose risks clearly outweigh the benefits.
