Key Takeaways
- Cluely is a desktop overlay tool built for live conversations and meetings, with a stealth undetectability feature gated behind the $75/month plan. A mid-2025 data breach exposed over 83,000 user accounts after admin credentials were left in a public GitHub repository.
- Final Round AI is the most complete real-time interview assistant, covering behavioral, technical, coding, case, and system design rounds with live answer suggestions, mock interviews, practice questions, and a resume builder in one platform.
- Interview Coder is a coding-only tool at $299/month, built specifically to overlay LeetCode-style solutions during live technical screens. It offers no support for behavioral, system design, or non-coding rounds.
- Final Round AI’s annual plan costs $25/month, making it the best value among the three for candidates actively job searching across multiple interview types.
- Cluely’s advertised 300ms response latency has been independently measured at 5-10 seconds in real pressure situations, which can create awkward pauses during live interviews.
- Interview Coder has triggered lifetime hiring bans at companies including Adobe, and industry analysis found that 38.5% of candidates were flagged for AI cheating behavior in technical interviews between July 2025 and January 2026.
- All three tools involve meaningful ethical and professional risk. Real-time interview AI use is not universally banned, but company policies vary widely and detection technology is improving rapidly.
- For most job seekers, Final Round AI delivers the broadest coverage across interview formats at the lowest sustained cost. Cluely suits candidates who need help in general meetings and calls beyond just job interviews.
Real-time interview AI tools have gone from niche products to a contested category in 2025 and 2026. Candidates use them to receive live answer suggestions during video interviews. Employers are increasingly aware they exist and are deploying detection systems in response. The tools themselves vary widely in what they actually do, how much they cost, and how real the risks are to your career if you get caught using one.
Cluely, Final Round AI, and Interview Coder are the three tools that come up most often when candidates research this category. They are different products solving partially overlapping problems. Cluely is a broad meeting assistant with stealth features. Final Round AI is an interview-specific copilot covering all round types. Interview Coder is a specialist tool built exclusively for coding screens.
This comparison breaks down what each tool actually does, what it costs, where each one works and where it fails, and which type of candidate should use which product.

What is Cluely?
Cluely is a desktop AI overlay tool that displays real-time answers and suggestions during live video calls and interviews. It listens to the conversation through your microphone, transcribes what is being said, and generates responses that appear on your screen as a floating overlay invisible to screen-sharing participants when the undetectability feature is active.
Originally built as a meeting assistant for general workplace calls, Cluely expanded its marketing toward interview use as the category grew. In 2026 it added an iOS app and a desktop widget to broaden its use beyond the core overlay. The product positions stealth as a differentiating feature, but undetectability requires the $75/month plan. The base Pro plan at $20/month does not include it, which is a significant gap given that stealth is the primary reason most candidates would consider this category.
Cluely made headlines in mid-2025 when a security researcher discovered the company had left admin credentials in a public GitHub repository. The resulting breach exposed the account data of over 83,000 users, including payment-associated information. This is a material consideration for any candidate entering their payment details and real employment history into the platform.
What is Final Round AI?
Final Round AI is an AI Interview Assistant purpose-built for job interviews rather than general meetings. It integrates with Zoom, Google Meet, and Microsoft Teams to capture interviewer questions in real time and display suggested responses on a screen overlay that is not visible during screen shares.
The platform’s scope is broader than the other two tools here. It supports behavioral rounds, technical rounds, coding problems, case interviews, and system design discussions. Beyond the live copilot, Final Round AI includes mock interview sessions with AI interviewers, a bank of practice questions organized by company and role type, and a resume-building tool. This positions it as a pre-interview preparation platform as well as a live assist tool, which is a meaningful difference from Cluely and Interview Coder.
Final Round AI’s pricing structure rewards longer commitments. The annual plan at $25/month billed annually is the best value. Monthly billing costs $90/month for the same access, making the annual plan significantly cheaper for anyone committed to a multi-month job search.
What is Interview Coder?
Interview Coder is a specialist real-time AI tool built exclusively for technical coding interviews. Created by Columbia University student Roy Lee and launched to widespread attention in 2025, it provides a native desktop overlay that displays AI-generated solutions to coding problems during live technical screens on platforms including Zoom, Microsoft Teams, HackerRank, CodeSignal, and CoderPad.
The tool’s native desktop architecture is its technical differentiator. Because it runs as a desktop application rather than a browser extension, it does not appear in screen-sharing captures the way browser-based tools might. This is the “undetectable” claim that Interview Coder markets heavily. The pricing reflects its specialist positioning: $299/month for Pro access with 1,000 credits, down from $499, or a Lifetime Pro option at $799. There is no meaningful free tier; AI features are gated behind paid plans.
Interview Coder is coding-only. It offers no help for behavioral questions, system design rounds, case interviews, or any non-coding portion of an interview process. For candidates navigating a full loop at a major technology company, which typically includes multiple non-coding rounds, Interview Coder covers only one stage.
Feature-by-Feature Breakdown
Interview Round Coverage
Final Round AI is the only tool of the three that covers the full interview loop. Behavioral rounds, coding problems, system design, and case interviews are all supported with live suggestions. For candidates at companies where a full loop spans four to six rounds across different formats, Final Round AI is the only option that provides live assistance throughout the process.
Cluely covers behavioral and conversational rounds reasonably well, as it was built for general meetings and handles open-ended discussion effectively. It struggles with structured technical problems because it is not designed around coding environments or LeetCode-style formats.
Interview Coder is highly effective for what it does, which is generating coding solutions in real time during technical screens. Independent reviews note that it handles isolated LeetCode-style problems well. Its limitation is scope: one round type, nothing else.
Stealth and Undetectability
Stealth mode is the feature candidates care most about, and the three tools handle it very differently. Interview Coder’s native desktop architecture provides the most reliable undetectability for coding platforms because it avoids the browser layer entirely. Final Round AI includes stealth functionality across its paid plans without requiring a higher tier. Cluely locks undetectability behind the $75/month plan, meaning the $20/month Pro plan is not usable in the screen-sharing context most interview candidates need.
The broader reality of detection in 2026 complicates all three tools. Fabric’s analysis of 19,368 interviews between July 2025 and January 2026 found that 38.5% of candidates were flagged for cheating behavior, with the rate rising to 48% for technical roles. Detection methods increasingly go beyond screen capture to analyze response timing, eye movement patterns, and answer consistency. Technical undetectability from screen sharing does not equal undetectability from behavioral analysis.
Pricing and Value
Final Round AI at $25/month on the annual plan is the best value for candidates actively searching across multiple interview formats. Cluely’s effective price for usable stealth functionality is $75/month, making it more expensive than Final Round AI for the same core use case. Interview Coder at $299/month is priced as a premium specialist tool and only makes economic sense for software engineers who face frequent technical screens and have already assessed the risk tolerance for their specific situation.
Security and Trust
Cluely’s 2025 data breach is a material consideration. The company exposed admin credentials in a public GitHub repository, leading to the compromise of over 83,000 accounts including payment-associated data. For a tool that requires access to your actual job search activity, interview content, and payment information, this track record matters. Final Round AI and Interview Coder have no comparable public security incidents.
Ethical and Career Risk
All three tools exist in ethically contested territory. Using AI assistance during a live interview without disclosure is considered deceptive by most employers and violates the terms of service of most hiring platforms. The career consequences of getting caught are real: Interview Coder has been documented to trigger lifetime hiring bans at companies including Adobe. EU AI Act provisions classify AI in hiring processes as high-risk, and the Illinois AI Video Interview Act requires explicit candidate consent for AI evaluation.
Candidates should weigh this against the reality that AI assistance during interview preparation, including mock interviews and answer coaching, is widely accepted and practiced. The ethical line is drawn at live, undisclosed use during an actual interview.
Cluely vs Final Round AI vs Interview Coder: Who Should Use Which?
Choose Final Round AI if you are actively job searching and want a single tool that covers all interview round types, including prep, practice, and live assistance. The annual plan at $25/month is cost-effective across a multi-month search. The resume builder and mock interview features make it valuable even before any live interview begins.
Choose Cluely if your primary use case extends beyond job interviews to general workplace meetings, client calls, and daily work conversations. The broader meeting assistant functionality makes the subscription useful year-round rather than only during active job searches. If you specifically need interview stealth mode, budget for the $75/month plan rather than the $20/month base tier.
Consider Interview Coder cautiously if you are a software engineer who faces frequent algorithmic coding screens, has assessed the detection and career risk specific to your target companies, and needs a specialist tool for that single interview type. At $299/month, the cost is only justifiable for active, high-volume technical interview pipelines.
Verdict
Final Round AI is the most practical tool for the broadest range of candidates. It covers all interview formats, includes preparation features that work before any live interview, has a reasonable annual pricing structure, and does not have a known security incident on its record. For most job seekers evaluating this category, it is the right starting point.
Cluely is the better choice when the meeting assistant functionality has standalone value beyond interviewing. The data breach history and the stealth pricing structure are legitimate concerns that candidates should factor into their decision.
Interview Coder is a specialist tool with a narrow use case and a high price. It is effective at what it does, but the $299/month cost and coding-only scope make it a hard justification for most candidates when Final Round AI covers coding rounds at a fraction of the price.
Frequently Asked Questions
Is using AI during a job interview legal?
Using AI assistance during a live interview is not illegal in most jurisdictions, but it violates the terms of service of most employers and hiring platforms, and is widely considered deceptive. The EU AI Act classifies AI in hiring as high-risk and imposes obligations on companies using it. Illinois requires explicit consent before AI evaluation of video interviews. Individual companies set their own policies, and some have implemented lifetime hiring bans for candidates caught using AI tools during live interviews.
Can employers detect Cluely, Final Round AI, or Interview Coder?
Detection depends on the method. Screen-sharing detection can be bypassed by native desktop apps like Interview Coder. However, companies increasingly use behavioral analysis including response timing, eye movement patterns, and answer consistency rather than screen capture alone. Fabric’s data from 19,368 interviews found that 38.5% of candidates were flagged for AI cheating behavior between July 2025 and January 2026, suggesting detection capability is more advanced than the tools’ marketing implies.
What happened with the Cluely data breach?
In mid-2025, hackers exposed the account data of over 83,000 Cluely users after the company left admin credentials in a public GitHub repository. The breach included payment-associated account information. The incident raised significant trust concerns about storing sensitive job search activity and financial data on the platform.
How much does Final Round AI cost?
Final Round AI offers a free trial tier, then scales to $25/month billed annually, $60/month billed quarterly, or $90/month on a month-to-month basis. The annual plan at $25/month is the most cost-effective for candidates in a sustained job search. A separate AI Job Hunter auto-apply feature is priced additionally at around $74.99/month for the Max tier.
Does Interview Coder work for all types of interviews?
No. Interview Coder is a coding-only tool designed for LeetCode-style algorithmic problems in technical screens. It does not provide assistance for behavioral questions, system design rounds, case interviews, or any non-coding portion of an interview process. Candidates needing full-loop interview coverage should consider Final Round AI instead.
What is the cheapest real-time interview AI tool?
Final Round AI’s annual plan at $25/month is the most cost-effective option among the three tools compared here. Cluely’s base Pro plan is $20/month but does not include stealth mode, which limits its practical use in screen-sharing interview contexts. Interview Coder starts at $299/month, making it the most expensive by a significant margin.
Can I use these tools during coding platforms like HackerRank or CodeSignal?
Interview Coder’s native desktop architecture is specifically designed to avoid detection on platforms including HackerRank, CodeSignal, CoderPad, and Zoom. However, these platforms continuously update their monitoring capabilities, and no tool can guarantee permanent undetectability. Both HackerRank and CodeSignal have terms of service that prohibit external AI assistance, and violations can result in candidate disqualification or employer notification.
Which tool is best for software engineers specifically?
Software engineers who face both algorithmic coding rounds and system design interviews will find Final Round AI the most comprehensive option, as it covers both round types. Interview Coder provides deeper real-time coding assistance for pure algorithmic problems but offers nothing for system design. Engineers who primarily need help with LeetCode-style problems during live screens and have weighed the cost and risk should consider Interview Coder; those who want broader interview coverage should use Final Round AI.
