Undetectable AI interview assistant on macOS

1. What gives you away

We went through every case an interviewer at a major tech company found suspicious. These are the main ones.

Screen share

• A dropdown, menu, or alert. With some tools, the settings you open mid-interview are on the interviewer’s screen too.

  

  

• The recording indicator. If you are sharing your whole screen, the indicator is in the shared view, where the interviewer can notice it. (Cluely, Interview Coder, Final Round AI, LockedIn AI, Sensei AI, LeetCode Wizard, Parakeet AI — they all follow the same pattern, and they are not the only ones.)

  

• The Dock, and ⌘-Tab. If the assistant has its own app icon, one accidental ⌘-Tab puts it on the screen you are sharing.

System

• Activity Monitor. Interviewers do ask candidates to open it and search the process list for anything that looks like an assistant. Unfortunately, all four of these are obvious. LockedIn AI is designed to have no process name at all — but nothing on a Mac runs without one, so a blank row only looks more suspicious.

  

  

  

  

• Focus leaving the interview window. A proctored coding platform counts that as a tab switch and puts it in the report, which makes you look suspicious.

Your behavior

• Your eyes read. When you think, your eyes drift up and off to the side. When you read, they move in straight horizontal lines and snap back to the start of the next one. A webcam can tell the difference. A second screen or a phone makes it worse: now your eyes leave the frame as well. This is why you never use an assistant that runs on your phone.
• Every answer takes the same beat. The tool needs the same time for every question: capture the screen, generate an answer, read it. So an easy question and a hard one both come back after the same pause. Detection vendors measure how much your response time changes from question to question, and a candidate whose pauses are all the same length gets flagged.
• Unnatural phrasing. Most interview assistants hand you a long block of text to read out loud, and that is the trap. There is too much of it to take in quickly, and what comes out of your mouth is too tidy to be your own. It sounds like AI, and an interviewer picks that up fast.

2. How Cowinx stays out of the screen share

• Invisible to screen sharing. Cowinx uses specific operating system APIs and window properties that designate its windows to be excluded from screen captures, recordings, and screen sharing sessions (like Zoom, Meet). This is a standard OS feature used by various overlay and privacy-focused applications.
• No native windows. Cowinx does not use them. Every window Cowinx opens inherits the same exclusion, so there is no window that can turn up in your screen share. The details are what matter here.
• No recording indicator. macOS lights the menu bar whenever a process records the screen. Cowinx takes the meeting audio through a system audio API, so the system counts it as audio and the indicator never lights.
• No Dock icon, no ⌘-Tab entry. Cowinx registers as a specific application type, the standard type used by menu bar utilities. macOS leaves those out of both.
• Clicks fall through. Cowinx marks the empty areas of the panel to ignore mouse events, a standard window property used by overlays. Those clicks go to the window underneath.

3. Activity Monitor & window focus

• Invisible in Activity Monitor.Cowinx runs quietly in the background, leaving no suspicious name or icon in your Mac’s Activity Monitor.
• Never the key window. Cowinx is a non-activating panel, the standard window type for palettes that should not take focus, so there is nothing for a proctored platform to log as a tab switch.

4. How Cowinx makes your behavior natural

• Natural eye focus. Everything is on the screen you are already looking at — no phone app, nothing to glance sideways at. You can put the panel anywhere and set its opacity, so the text sits close to where you are already looking.
• Timing and phrasing. Cowinx answers short: one line of conclusion, then keyword-first bullets. You take in the logic quickly and put it in your own words. The time you spend reading and rephrasing reads as ordinary thinking time, and it changes with how hard the question is. The answer comes out the way you understood it, so it sounds like you.
• Natural mouse movement. Every action is a global hotkey — answer, page through, hide, quit. You never move the mouse to another window, and the interviewer never watches you click.

5. Check it yourself

• Setup check — run both checks in your browser.
• Launch checklist — the full routine before the call.
