Can Interview Coder be detected? Parakeet AI and Otter too

All three run on the candidate's side. A video call carries only their camera, their microphone and whatever they choose to present, so the call itself rarely shows you the tool. This page sets out what each one says about itself, what you can and cannot see, and what to do about it.

The three tools at a glance

Everything in the table is each company's own description, read on October 29, 2026. These are claims, not tests.

Interview Coder

What it is, in its own words

Interview Coder describes itself as "a desktop app designed to help job seekers ace technical interviews". Its site offers versions for Windows and Mac and lists "Audio support for real-time guidance". Cluely's founders, Roy Lee and Neel Shanmugam, were suspended from Columbia University for developing it, as TechCrunch reported in June 2025.

How it says it stays hidden

The site says the "Overlay remains hidden when sharing your screen", calls the app "100% Invisible to Screen-Recording", and says it "allows clicks to pass through to underlying windows". It marks a list of interview platforms as "Undetectable".

What you can and cannot see

You see the candidate's face and a shared screen that looks clean. You usually cannot see the overlay, or that the app is running. The claim has limits, though. Interview Coder's own FAQ asks: "Why is Interview Coder visible on Google Meet with Windows 10?"

Parakeet AI

What it is, in its own words

Parakeet AI calls itself "Your Real-Time AI Interview Assistant". It says it "Detects questions live and suggests answers" and "reads code shared on your screen". It says "The desktop app runs on Windows and macOS".

How it says it stays hidden

Parakeet says it "stays completely invisible to others" and is "hidden from the Dock, with no icon or activity indicator". It marks eight video and coding platforms as "Verified" for this.

What you can and cannot see

A normal call, sometimes with a short pause before each answer. Parakeet also says it is "built for conversations where AI assistance is permitted". That is a useful line to quote back: say at the start of an interview whether AI help is allowed.

Otter

What it is, in its own words

Otter is a notetaker. Its site says "Otter transcribes every meeting" and that its agent can "automatically join all your Zoom, Microsoft Teams, and Google Meet meetings". Otter also sells a Recruiting Agent to hiring teams, described as "Get real-time help during interviews". It does not market help to candidates.

Bot or no bot

When Otter's agent joins, it shows in the participant list. Otter's Chrome extension works differently. Its store listing says "No-bot in Google Meet" and "no extra participant joins your call", and adds "You can see live transcript in the meeting." A transcript on the candidate's screen, or read by someone else, does not appear in your view of the call.

Final Round AI, LockedIn AI and other hidden helpers

• Cluely says it is "Invisible to screen share." and "Doesn't join meetings." See whether Cluely can be detected and Cluely vs Interview Coder.
• Final Round AI offers "real-time answers in a private window only you can see". Its FAQ is more careful: its Stealth Mode "is designed to keep" windows "out of supported screen shares and recordings". More in can interviewers detect Final Round AI.
• LockedIn AI says it "Floats over Zoom, Meet and Teams" and suggests a phone: "Prop it next to your laptop".

How “hidden from screen sharing” works

Windows and macOS both let an app ask to be left out of screen capture. Microsoft's documentation says that with this setting "the window does not appear at all" in a capture, while it still shows on the person's own monitor. App frameworks expose it as one switch; Electron's documentation describes it as: "Prevents the window contents from being captured by other apps."

It is not a guarantee. Microsoft's own page says "there is no guarantee" the setting protects content. Electron notes that newer Mac capture "will capture your window despite win.setContentProtection(true)", and Apple describes the older flag as "A legacy constant that macOS no longer uses." So a helper may show up on one computer and not another, which is why watching a shared screen gives you an uncertain answer either way.

Overlay remains hidden when sharing your screen

What interviewers can do on the call

1. Say at the start whether AI help is allowed, and ask candidates to close other apps before you begin.
2. Ask follow-up questions that build on their own earlier answers.
3. Ask them to explain code they just wrote, line by line, in their own words.
4. Listen for a second voice, typing while you talk, or an echo of your question.
5. Treat a pause as a reason to ask, not as proof.

Interviewers do sometimes catch these tools. One recruiter on Reddit saw a hidden app appear in a screen share, with "options which she was choosing to respond". An engineer described "pauses after each question felt like the AI loading the answers". But a pause also happens to careful, nervous and second-language speakers, so it is a judgment, not a finding. Why that matters is covered in ask for the false-alarm rate.

Why a check on the candidate’s computer works better

Verified Call checks the person on the call, before it starts and while it runs, without joining. It checks for hidden AI answer tools, camera software, face swaps, deepfakes and AI avatars sent through camera software, and someone else answering. It checks that the voice on the call matches the person who did the check.

It works inside the video calls you already run. No bot in the participant list. It checks on the person's own computer, so it sees what a video call cannot carry: a tool hidden from screen sharing, or a face sent in through camera software. Each call is checked fresh. The host sees a plain result, with proof beside any flag, and a person can decline the check and still join with the host's link; the host sees that they declined.

We publish how we test, false alarms included. In our own testing, each of 4 hidden AI answer tools was found in 30 of 30 tries, with 0 of 30 false alarms with no AI tool open and 0 of 30 with everyday apps open (October 4, 2026). Camera software and direct cameras were read right in 20 of 20 live calls (October 2, 2026). Every condition is on the Research page.
