LockedIn AI markets itself as a fully hidden, undetectable interview copilot with system audio, focus protection, Activity Monitor aliasing, and hotkeys that never reach websites. We tested the macOS desktop app, then reran the important failure classes in CTRLpotato.
The problem was not only raw AI output. In our tests, LockedIn leaked shortcut keys to the active page, stole focus, changed the cursor, exposed LockedIn helper processes, failed to capture system audio, and wrapped everything in a chaotic UI that felt unusable under interview pressure.
LockedIn can generate AI content, but our macOS desktop test did not feel safe or practical for a real interview. CTRLpotato is stronger when focus, shortcut isolation, audio, answer shape, and fast control matter.
LockedIn's strongest desktop claims are about invisibility, but our test found leaks in the interaction layer: hotkeys reached the page, focus changed, the cursor changed, and helper processes remained visible.
LockedIn's public pricing showed an Unlimited plan listed at $54.99/mo, and its support docs say Desktop App access requires Unlimited Professional or eligible Credit plans. CTRLpotato starts with 10 free AI answers and a $39 Sprint Pass.
| Claim / check | Observed result | Why it matters | Proof |
|---|---|---|---|
| Stealth Mode screen-capture hiding | Pass Hidden in preview | In our own capture preview, the overlay did not appear. That pass is why the real story is the interaction layer around it. | View balance note |
| Undetectable hotkeys registration | Fail Keys reached the active page | LockedIn says shortcut keystrokes never propagate to websites or web apps. In our test, the browser page still saw the shortcut combo. | View hotkey proof |
| Active Tab Isolation / Focus Protection | Fail Focus loss observed | Interview and assessment pages can monitor when the active window loses focus, even if they cannot see the assistant. | View focus proof |
| Invisible in Activity Monitor | Fail Brand helpers visible | The main process can be renamed, but LockedIn helper processes and app identity still appeared locally in our macOS Activity Monitor checks. | View OS proof |
| Click-through / invisible overlay | Fail Cursor changed | The cursor changed over hidden UI and resize surfaces. During screen share, pointer changes can expose interaction with something that should not be there. | View cursor proof |
| System Audio Capture | Fail System audio failed | LockedIn markets crystal-clear system audio capture. In our test clip, system audio was not captured, which breaks spoken interview and system-design workflows. | View audio proof |
| Auto real-time answers | Fail Auto mode missed / stalled | The product promised live answers, but our run showed stale output while current questions queued up and the user had to ask it to answer. | View auto-mode proof |
| Concise response settings | Fail Long walls of text | Even with concise coding answers selected, LockedIn returned large code blocks and paragraph-heavy answers that are hard to use live. | View answer-shape proof |
LockedIn's screen-capture hiding appeared to work in its own preview, so we are not claiming a screen-share pixel failure. The bigger problem is more practical: the active page saw shortcut keys, the page lost focus, the cursor changed over hidden UI, Activity Monitor still exposed LockedIn helpers, and system audio failed in our test.
These are not abstract stealth concerns. They are normal ways candidates get checked: keyboard events, active-window monitoring, cursor behavior, Activity Monitor, installed apps, and system audio. Hidden pixels alone do not make a tool safe to use.
LockedIn says global hotkeys never propagate to websites or web apps. In our keyboard event test, the active page still registered the shortcut combo while LockedIn was used.
Using LockedIn changed the active window in our test. That matters because interview and assessment platforms can monitor blur/focus events.
Out of the box, the app appeared locally as LockedIn with branded helper processes. That is a serious problem when a proctor asks to open Activity Monitor.
LockedIn can rename the main process, but in our test the helper processes still contained LockedIn. A cosmetic alias is not enough if the original app name remains searchable.
A renamed main process only helps if the rest of the local identity disappears too. In our test, the app identity and helper naming still made the assistant recognizable.
The cursor changed over LockedIn surfaces. During screen share, that can reveal interaction with an invisible assistant because the pointer changes where nothing visible should exist.
This is where LockedIn performed worst. It may generate some usable AI content, but the app around that content felt overloaded, brittle, and too hard to operate while someone is waiting for an answer.
Auto mode was the live-interview promise. In our run, current questions queued up while the answer area stayed stale and the user had to type 'answer please.'
Even with concise coding answers selected, LockedIn returned a large full-code response. That can be useful as prep material, but it is hard to use while someone is waiting.
When LockedIn finally returned guidance, it started with generic AI phrasing and long paragraphs. That is not a live-answer shape we would want to read mid-interview.
This was the least interview-ready UI of the competitor apps we tested: dense, low-contrast, overloaded, and difficult to operate under pressure.
In one context test, LockedIn failed to use the uploaded context cleanly and returned an answer that did not match the source material.
Same risk category, same active-page setup where possible, side by side.
We triggered the assistant shortcut while a browser test page was active. In monitored assessments, the key question is whether shortcut key presses still reach the active page.
Blocking assistant shortcuts matters because assessments can monitor key events even when they cannot see the assistant.
For spoken interview and system-design prompts, the first requirement is boring but critical: the app has to capture the audio reliably before the model can help.
When the task is spoken aloud, audio reliability matters more than the model list on the pricing page.
LockedIn's support docs say there is no free trial that lets you start a live Desktop App session. They also say Desktop App support requires Unlimited Professional or eligible Credit plans. Its public pricing page showed an Unlimited plan listed at $54.99/mo, and support docs describe credit sessions as per-minute usage.
CTRLpotato starts with 10 free AI answers, then lower-commitment options: Lite at $29/mo, Sprint Pass at $39 once, and Pro at $59/mo quarterly or $69/mo monthly.

Whether LockedIn kept shortcut keys out of the active page, preserved focus, avoided cursor tells, avoided obvious local system exposure, captured system audio, answered automatically, and produced a usable first visible answer.
This was a macOS desktop test. Paid tiers, settings, operating-system versions, and future LockedIn releases may behave differently. We are not claiming a receiver-side screen-share pixel failure; every claim on this page is tied to the screenshots and videos shown here.
We are not claiming LockedIn cannot produce coding or interview content. The issue in our test was the product layer around that content: controlling it, reading it, and trusting it under pressure.
Unlike Interview Coder, we are not claiming a receiver-side screen-share failure here. Screen-capture hiding appeared to work, but keyboard shortcuts, focus, cursor behavior, audio capture, and process names still gave the app away.
LockedIn's Duo human-helper approach is genuinely different. We didn't evaluate Duo itself in this review, so our findings focus only on the desktop app we tested.
LockedIn's tested workflow exposed a lot of modes, controls, settings, model choices, assistant states, and stealth options. That can look powerful on a feature list, but in our test it became hard to control during the actual live moment.
Instead of one workflow trying to do everything, CTRLpotato separates screenshot capture, Follow Up, Live Coach, answer customization, model choice, and Mobile Mirror into dedicated tools. That keeps the app predictable under pressure and lets you choose the right workflow for the interview in front of you.
LockedIn gets credit for ambition and for generating some useful content. The practical problem is that the desktop product around the AI answer did not feel reliable enough for a real interview or monitored assessment.

AI answers are only half the product. The workflow decides whether you can actually use them during an interview or assessment: what context goes in, what answer comes out, whether focus stays put, whether the cursor gives you away, whether audio is captured, and whether you have Mobile Mirror when the desktop is crowded.
Try CTRLpotato - 10 free usesCTRLpotato is a strong LockedIn AI alternative if you care about live interview workflow rather than just AI answers. It gives you more control over context, follow-ups, answer style, screenshots, keyboard shortcuts, local visibility, and how you interact with the assistant during an interview.
LockedIn AI makes strong stealth claims. In our macOS testing, screen hiding appeared to work, but we still observed shortcut leakage, focus loss, cursor changes, visible helper processes, and a system-audio capture failure. Test your own setup before relying on any undetectability claim.
Yes. In our testing, LockedIn shortcut key presses reached the active browser page. CTRLpotato's bound shortcuts did not reach the same page in the comparison test.
Yes. Using LockedIn changed the active window in our focus logger test. Some interview platforms monitor focus changes, making this an important part of the workflow.
Yes. LockedIn remained visible by brand name, and helper processes stayed visible even after enabling the process rename option.
LockedIn advertises system audio capture, but it failed in our comparison test. Without the interview audio, the assistant missed the current question and couldn't generate a useful answer. CTRLpotato captured the same prompt successfully.
It may work for some HackerRank interviews, but in our testing we observed focus changes and keyboard shortcut leakage, both behaviors that can matter on monitored coding platforms. Always test your exact setup before using any interview assistant in a real assessment.
It may work for some CoderPad interviews, but we would test your exact setup before relying on it. In our macOS testing, we observed focus loss, keyboard shortcut leakage, visible helper processes, and a system-audio capture failure. Those workflow issues matter regardless of whether the interview is on CoderPad or another monitored platform.
Yes, LockedIn AI was able to generate useful answers for clean LeetCode-style coding screenshots in our testing. However, we also found the desktop workflow difficult to rely on during a real interview due to focus changes, shortcut leakage, unreliable audio capture, and a busy interface. Practice coding and live assessments are different environments, so test your exact setup first.
LockedIn's public plans started at $54.99/month. Desktop App support also depends on plan eligibility according to its documentation. CTRLpotato starts with 10 free AI answers, then Lite, Sprint Pass, and Pro plans depending on how often you interview.
For our macOS testing, no. LockedIn generated some useful AI content, but the desktop workflow repeatedly got in the way. We observed focus loss, shortcut leakage, visible helper processes, unreliable system audio capture, and an interface that became difficult to operate under interview pressure.
