The FirstProactive& Undetectable
Interview Copilot
Native system-level stealth keeps you 100% invisible. Sub-second latency and smart context memory deliver the perfect answer before they even finish the question.

NATIVE FEEL.
ZERO DISTRACTION.
How undetectable, exactly?
Every promise we make is worthless if you can be detected. This is the one thing Cowinx cannot afford to get wrong — so we re-verify it every day.
01 — Compositor Exclusion
Invisible at the OS render layer.
Most “stealth” tools hide a window from the app. Cowinx is excluded by macOS itself, before any frame reaches a capture buffer.
02 — Dock Suppression
Zero dock presence.
LSUIElement makes Cowinx a background-only process. No icon, no badge, no bouncing — the floating panel is your only surface.
03 — Process Stealth
Invisible in Activity Monitor.
Cowinx runs under a neutral process name with no user-facing binary identifier. Search Cowinxin Activity Monitor and you get “App Not Found” — nothing to flag, nothing to screenshot.
Stealth you can trust on interview day.
We continuously verify invisibility and stability across major meeting and coding platforms.
Cowinx vs. the rest.
Hard numbers where we have them, checkmarks where we don't — based on each tool's own public claims and our own testing.

Questions candidates actually ask.
Plain answers, even to the uncomfortable ones.
Will I get caught?
Cowinx is excluded at the macOS compositor layer, which means the screen-share buffer never sees our window in the first place — it is not hidden from a buffer that includes it, it never makes it into the buffer. We verify this daily across Zoom, Teams, Google Meet, Webex, FaceTime, and more on every OS and app point release.
Honest caveat: no tool can guarantee 100% invisibility forever. What we can guarantee is that we run a regression test suite on every macOS and Zoom update, and ship a patch within hours if anything shifts. That is how we are different.
Is this ethical?
We believe interviews should measure your ability to solve real problems — not your ability to memorize trivia or out-perform anxiety. Cowinx is a thinking aid, the way a calculator is a thinking aid in a math exam that long ago stopped forbidding them. You still have to understand the answer, speak it, and defend it. If that feels wrong to you, do not use it.
What if Zoom or macOS updates and breaks stealth?
We run automated stealth regression tests every hour against the latest Zoom, Teams, Meet, and macOS builds. If a regression is detected, our team ships a patch — average turnaround is under 6 hours. You will see the exact timestamp of our most recent successful test above the platform matrix.
Why macOS only?
Windows does not expose an equivalent compositor-level capture exclusion API. Any “stealth” tool on Windows is just hiding a window from a list, which breaks the moment a screen-capture tool decides to include it. We would rather not ship a Windows build than ship one that is quietly unsafe.
Can my employer find Cowinx on my Mac afterwards?
Cowinx lives in ~/Applications and writes minimal state to ~/Library/Application Support. If you uninstall it, the app bundle and caches are removed. We do not store audio, and the transcript is kept locally unless you explicitly export it.
Does it work for non-English interviews?
Yes — 7 languages today: English, Spanish, French, German, Italian, Portuguese, and Mandarin Chinese. Language is auto-detected and routed to the best ASR per language (AssemblyAI for EN/ES/FR/DE/IT/PT, Qwen3-ASR for ZH).
