Screen Capture

Dusky takes screenshots of interview questions so the AI can analyze them. The capture is invisible — it never appears in screen share or recordings.

How to capture

Press Cmd/Ctrl+H to take a screenshot.

Dusky captures whatever is currently on your primary display. You can queue up to 5 screenshots — older captures are automatically discarded to save memory.

Capture + Solve in one step

Press Cmd/Ctrl+Enter to screenshot and immediately send the image to AI for analysis. This is the fastest workflow when a coding question appears on screen.

Adaptive behavior

When audio transcription is active and already has a transcript, Cmd/Ctrl+Enter processes the transcript instead of taking a screenshot. This means you do not need to capture spoken questions manually.

Why it is invisible

Dusky registers its window as screen-share-excluded at the operating system level. On macOS, this uses the system content protection API. On Windows, Dusky uses the display affinity API to exclude itself from capture. Video conferencing apps like Zoom, Google Meet, and Microsoft Teams skip excluded windows when sharing your screen. Your interviewer never sees Dusky.

The app window is also:

• Hidden from the Dock (macOS) or Taskbar (Windows) in stealth mode
• Hidden from the app switcher (Cmd+Tab / Alt+Tab) in stealth mode
• Protected from screen recordings via content protection

For more on invisibility, see Stealth Mode.

Where screenshots are stored

Screenshots are saved as PNG files in Dusky’s local application data folder. Up to 5 screenshots are kept at a time — when you capture a sixth, the oldest is automatically deleted from disk.

Screenshots persist across sessions so Dusky can restore your context if you quit and relaunch during an interview. You can delete individual screenshots from the queue, or clear all data from Settings.

When you press Cmd/Ctrl+Enter to solve, the screenshot image data is sent to Dusky’s AI backend for analysis. The backend processes the image and returns a response — it does not store your screenshots permanently. See the Data Handling page for full details on how your data is processed.
