AI interview cheating tools are apps that run on the candidate's computer or phone during a live interview: they listen to the interviewer, can read what is on the screen, and show suggested answers in a window that, their makers say, does not appear in screen shares or recordings. As of October 2026 the best-known examples include Interview Coder, Final Round AI's live interview assistant, LockedIn AI and Parakeet AI; Cluely, the name most people have heard, now markets itself as an "undetectable" AI assistant for meetings. They make polished, generic answers easy. What they cannot supply is the candidate's own memory of their own work, which is where a good interview should spend its time.

This page explains how these products work and what they claim. Detecting AI-written answers is covered in how to detect AI-generated interview answers, reading from a script in how to tell if a candidate is reading answers, and software that flags AI help in tools to detect AI use in interviews.

How do AI interview assistants work?

Most of them combine three pieces:

  • Listening. The app captures the call audio, transcribes the interviewer's question and sends it to a language model, often with the candidate's resume and the job description already loaded.
  • Reading the screen. For coding interviews, the app captures the problem shown on screen, such as a shared editor or an assessment platform, and returns code and an explanation.
  • A hidden window. The answer appears in a small overlay the candidate can place near the camera, so their eyes stay roughly on the interviewer.

The hidden window relies on features operating systems already provide. On Windows, Microsoft documents a window setting under which "the window is displayed only on a monitor. Everywhere else, the window does not appear at all," intended for things like recording controls. Microsoft also notes it is not a security feature and does not stop someone photographing the screen. In practice it means a candidate can share their whole screen while a window you cannot see sits on top of it.

Some products go further. LockedIn AI describes a feature that lets a friend join the candidate's private session as a remote helper who is "never visible to the interviewer," which is a proxy helper delivered as software.

Which tools are candidates using, and what do they claim?

Everything in this table comes from each company's own site, checked in October 2026. The claims are theirs; we have not tested whether the tools are in fact undetectable.

Two details stand out. Cluely presents itself today as a meeting assistant rather than an interview tool, and Parakeet AI tells users the product is for conversations "where AI assistance is permitted" and to check the rules first. The technology is the same either way; whether using it is cheating depends on what the candidate was told.

How common is live AI help in interviews?

The second number matters most for interviewers: many candidates do not think live AI help is wrong unless someone tells them it is. More figures, each linked to its source, are in candidate fraud statistics.

Where do these tools help a candidate, and where do they fail?

Interview formatHow much a tool helpsWhy
Definitions, trivia, textbook algorithm problemsA lotThe answer exists in public and the model has seen it many times
Standard behavioral questions ("Tell me about a time...")SomeIt can draft a plausible story from the resume, but the story is generic
Follow-ups on the candidate's own historyLittleThe tool does not know who signed off, what broke in week one or why the team chose that system
Your own scenario with constraints that change midwaySome, with lagEach change needs a new transcription and answer, and the pauses show
Collaborative work on your code, talking while typingLimitedReading and typing at once, in a conversation, is hard to fake
In-person conversation or whiteboardVery littleNo screen to hide an overlay on

The pattern is consistent: the more the interview depends on the candidate's own past and on back-and-forth with you, the less any assistant can do. That is also what a well-run structured interview rewards anyway. Questions built on that principle are collected in interview questions that expose AI-assisted answers.

What should you change about how you interview?

  1. Say the rule before the interview. Whether live AI help is allowed should be in the invitation, in writing, for every candidate. A tested template is in candidates using AI in interviews: a fair policy.
  2. Decide what you are testing. If the job uses AI every day, consider allowing it and assessing how the candidate uses it. Canva said in June 2025 that it now expects backend, machine learning and frontend candidates to use AI coding tools such as Cursor and Claude in technical interviews, and evaluates how they clarify requirements and catch problems in the AI's code.
  3. Spend time on follow-ups, not openers. Score the second and third answer on a topic, not the first. Fluent openers are exactly what the tools produce.
  4. Do not lean on screen sharing. As the Windows documentation above shows, a shared screen can hide a window, and a phone on the desk is not on screen at all. Asking for a camera tour of someone's room is intrusive and proves little.
  5. Keep one stage the tools cannot reach, if the role justifies it: an in-person conversation, or a supervised session. The trade-offs are in should we bring back in-person interviews.
  6. Treat software flags as prompts. Interview Signal, which we make, has a private answer check that flags answers that read as AI-written or read out and suggests a question to try; it never changes a score and never appears in a client submittal. Any flag, from any tool, is a reason to ask a better question.

What should you do if you think a candidate is using one?

The same thing you would do for any suspected outside help: do not accuse, ask follow-ups about their own experience, and score only what they showed. Neutral lines that keep the interview going:

  • "Let's set the polished version aside. What actually happened on that project?"
  • "Before you go on, who asked you to do that, and what did they say?"
  • "Can you walk me through it the way you'd explain it to a new teammate?"

Write down observations, not conclusions ("could not say what went wrong after two follow-ups"), and add the same next step for every candidate at that stage if you remain unsure. If the issue is that the person on camera may not be the applicant at all, that is identity fraud, and the response is in what to do if a candidate used a proxy.

Is using an AI interview assistant illegal?

In most cases the consequences come from the employer's rules rather than from a specific law: a rejected application, or a withdrawn offer if the candidate broke a rule they had been told about. It becomes a different matter when the tool is used to pretend to be someone else, such as altering a face or voice to impersonate another person, which is identity fraud. Because the line depends on what you told the candidate, write the rule down and apply it to everyone. This is general information, not legal advice.

Questions people ask

What is Cluely, and can candidates use it in job interviews?

As of October 2026, Cluely describes itself as an undetectable AI assistant for meetings that listens to the conversation, reads the screen on request and shows real-time answers in a window it says never appears in shared screens or recordings. It is marketed for meetings rather than interviews, but nothing technical stops a candidate from running it, or a similar tool, during a video interview.

Can interviewers see Interview Coder or similar tools when the candidate shares their screen?

Usually not, if the vendors' claims hold. Interview Coder, Parakeet AI and Final Round AI all say their windows stay out of screen shares, and Windows has a documented setting that lets an app's window appear on the monitor but not in captures. A screen share therefore proves very little about whether help is on screen.

How can you tell if a candidate is using an AI interview assistant?

You usually cannot see the tool, so look at the answers. Assistants produce fluent, general answers to standard questions but cannot supply the candidate's own memories. Follow-up questions about who was involved, what went wrong and what the candidate did next expose the gap, and a short pause before every answer, including easy ones, is a pattern worth probing.

Do any companies allow candidates to use AI during interviews?

Yes. Canva said in June 2025 that it now expects backend, machine learning and frontend engineering candidates to use AI coding tools such as Cursor and Claude in its technical interviews, and it assesses how they clarify requirements and catch problems in AI-generated code. What matters is that the rule is stated in advance and applied to everyone.
