We tested Cluely on macOS with mock behavioral interviews, system-design follow-ups, coding screenshots, and undetectable-mode desktop behavior. Then we recorded the evidence and reran the same failing scenarios in CTRLpotato.
Cluely did well correcting a false interviewer premise and outlining a URL-shortener architecture. But in our tests it also missed a simple debugging fix, produced long written answers, had rough desktop ergonomics, and showed focus loss, shortcut-key leakage, cursor tells, and OS-visibility issues even with undetectable mode active.
Cluely had useful general-assistant moments. CTRLpotato was stronger when the task required coding context, answer-shape control, and interview-speed decisions.
The repeated issues were not abstract model quality. They were current context, answer shape, focus loss, shortcut key leakage, cursor tells, system visibility, and whether the first visible response was usable while someone was waiting.
The page includes same-scenario reruns, control-check videos, balance examples where Cluely worked, and first-launch evidence from the test machine.
Same prompt, same screen, same failure condition, side by side.
We showed both apps the same failing top_k_frequent task. The correct answer should be visible immediately: change len(heap) >= k to len(heap) > k.
Cluely suggested heap = [], which was already present and did not fix the failing test. 
CTRLpotato led with the one-line fix and explained why the original code kept only k - 1 items. Same failing test; the first visible fix decided the coding result.
For 'Tell me about yourself,' the win is not prettier prose; it is controlling the answer shape while someone is waiting.
Cluely produced useful content, but the default shape was long written prose. 
CTRLpotato showed bullets, live controls, model choice, and Customize Answers. CTRLpotato's advantage is answer-shape control, not prettier resume prose.

Cluely had good moments in clean meeting-style prompts. The harder question was whether the desktop workflow stayed precise, controllable, invisible, and useful under live interview pressure: no focus loss, no cursor tell, no shortcut-key leakage, and no obvious app name in system checks.
All captures in this section were made with Cluely's undetectable mode active. These checks are about live control, not abstract stealth claims.
Cluely becomes the active app during use, causing the interview or assessment window to lose focus, which some platforms can monitor.
Interviewers sometimes ask candidates to open Activity Monitor, Finder, or installed apps. Cluely remains visible there by name.
Repeated Control/Cmd key presses can still be detected by the assessment while triggering AI shortcuts.
The pointer changes shape over Cluely's controls, revealing interaction with an assistant that is supposed to stay invisible.

Whether Cluely captured the current context, produced a usable answer quickly, respected visible code, avoided stale/filler turns, and stayed controllable on a real desktop without focus loss, cursor tells, shortcut-key leakage, or obvious system visibility.
This is a free / limited desktop-flow test on macOS. Paid tiers and future versions may behave differently. The desktop-control captures shown here were recorded with Cluely's undetectable mode active, and every claim below is tied to the runs shown on this page. In our run, Cluely's 10-minute free trial window ended around eight minutes.
Coding context: it worked in a second run In a similar multi-window coding test, Cluely did identify the correct one-line fix. The issue is inconsistent reliability in the live workflow.
Wrong premise: Cluely handled this well When the interviewer assumed an accounting-course project that was not in the resume, Cluely correctly suggested correcting the premise instead of inventing details.
Cluely's strongest moments in our tests were general interview notes: correcting a false premise, summarizing a URL-shortener architecture, and producing polished written answers. That is useful, but it is not the same as a fast, precise coding-interview workflow.
CTRLpotato separates Ask AI, Follow Up, Live Coach, area screenshots, selected text, top-tier model choice, answer customization, controls that do not steal focus, dynamic local identity, Mobile Mirror, and Session Debriefs so you can control context, answer shape, how the app is controlled, and where the answer appears.
Cluely gets credit where it behaved well, including answer-style support; the workflow and stealth-control gap is still visible.

System design prompt: Cluely understood the URL-shortener task, but the answer was closer to written notes than a 20-second spoken response. 
Earlier follow-up transcript: the transcript included filler-like turns such as 'Thank you' and '.', which made the live context harder to trust. 
First-launch friction: Cluely asked for an administrator name and password in our macOS test. 
First-launch reliability: after the administrator authorization was rejected, Cluely showed an uncaught Electron JavaScript error. 
Applications folder: with undetectable mode active, Cluely still appeared by name as a normal installed app. 
Cursor test: with undetectable mode active, the pointer changed over a Cluely input surface, creating a visible tell during screen share. 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 shape comes out, and where the answer appears under pressure.

Try CTRLpotato - 10 free usesCTRLpotato is a strong Cluely alternative if your priority is interview and assessment workflow control: area screenshots, selected text, explicit Ask AI and Follow Up modes, top-tier model choice, answer customization, controls that do not steal focus, normal cursor behavior, shortcut keys that do not reach the assessment, dynamic local app/process identity, and Mobile Mirror as a remote control and second screen.
On the same failing top_k_frequent coding task, Cluely suggested heap = [], which was already in the code. CTRLpotato led with the correct one-line fix: change len(heap) >= k to len(heap) > k. On the same behavioral prompt, CTRLpotato showed a more compact spoken-answer format.
In our macOS free desktop tests, Cluely was inconsistent for coding. It missed one simple one-line debugging fix, but did find the correct fix in another similar multi-window test. We would not treat it as a dedicated coding-interview workflow without testing your exact setup first.
We tested Cluely's desktop flow with undetectable mode active. In our macOS test, Cluely still became the active app, modifier shortcut keys still reached the assessment, the cursor changed over Cluely controls, and the real app name appeared in normal system surfaces such as Activity Monitor and Applications.
We tested the Cluely macOS desktop app in July 2026 using mock behavioral, system-design, and coding interview scenarios. Screenshots and videos on this page are from those tests.
