AI Agent for technical interviews
Cowinx is a native macOS AI interview assistant for technical interviews. It transcribes audio in real time, answers coding questions, and analyzes your screen while staying hidden from common screen-sharing tools.
NATIVE FEEL.
ZERO DISTRACTION.
Intelligence built for interviews
Built to help you move through coding rounds, system design prompts, and live screen-share interviews with faster, context-aware answers.
State-of-the-Art Models
Powered by the latest and most capable AI models. Your subscription automatically upgrades to the newest flagship models as they are released, ensuring you always have the best reasoning engine.
Auto Context & Q&A
Automatically listens to the meeting, identifies interview questions, and analyzes the context. It generates professional, natural-sounding answers specifically designed to be read aloud smoothly.
On-Demand Vision
Manually trigger Q&A whenever you need it, or capture your screen to instantly analyze coding problems, whiteboard challenges, or system design diagrams.
How it works
A native macOS stealth layer implemented through four core technical mechanisms.
01 — Stealth Window Rendering
Excluded from every capture pipeline
Cowinx is written in Swift and uses system-level macOS window rendering to keep its interface out of screen capture. QuickTime, screenshots, and screen-sharing apps like Zoom, Teams, and FaceTime see only your desktop.
02 — Dock Integration Suppression
Zero dock presence
The LSUIElement flag in the application bundle instructs macOS to treat Cowinx as a background-only process. No icon, no badge, no bouncing — interaction happens exclusively through the floating window interface.
03 — Native Swift Architecture
Pure Swift, zero runtime overhead
Built entirely in Swift with AppKit and Core Graphics — no third-party runtimes. Under 50 MB memory footprint with sub-second launch, running inside macOS's own sandboxing and code-signing infrastructure.
04 — Non-Interactive Window Model
Never interrupts your flow
Apple Event Kit's click-through model means the window accepts zero mouse events and never becomes the active application. No keyboard focus interception, absent from ⌘+Tab, no activation state — Cowinx is simply not there, to the rest of the OS.
Tested daily
Stealth you can trust on interview day.
We continuously verify invisibility and stability across major meeting and coding platforms.
Why Cowinx is Different
Every tool claims stealth. The difference is how it's built.
