Screen-Share Stealth and Permission Setup
Why the assist window is invisible to screen sharing and recording, which permissions it needs, and the privacy notes on local recognition.
For Interview Copilot to be genuinely usable, the prerequisite is that "the other side can't see it." Kuaimian's assist window achieves this through screen-share stealth: it renders only on your local screen, never enters the screen-share stream, and won't be captured by recording. This page explains how stealth works, which system permissions you need to grant and why, how to set it up on each platform, and the privacy boundaries of local recognition.
How screen-share stealth works
Screen sharing and recording capture the visual stream of "the window or screen region being shared." Kuaimian's floating window is marked at the system level as excluded from capture, so:
- You can see the prompts on your own screen;
- The image shared with the interviewer, and any video captured by recording software, does not contain this window.
Before a real interview, it's a good idea to first start a test share or recording to confirm the window really doesn't appear in the image, then use it with confidence.
Which permissions, and why
| Permission | Purpose | What happens without it |
|---|---|---|
| Screen sharing / recording | Lets Kuaimian understand the questions and conversation on screen; ⌘E screenshots also depend on it | Can't screenshot to feed questions, can't read on-screen content |
| System audio capture | Recognizes the interviewer's spoken questions in real time | Can't hear questions; only manual screenshots work |
Both permissions serve only the single main chain of "hear / read the question → give ideas."
Setup per platform
macOS
- Open System Settings → Privacy & Security.
- Under Screen Recording, check Kuaimian — used for reading the screen and ⌘E screenshots.
- Under the relevant Microphone / System Audio items, grant Kuaimian audio capture permission.
- After authorizing, restart the client for the permissions to take effect.
Windows
- The first time you turn on the copilot, grant screen / audio capture permission via the system prompts.
- If blocked by security software, allow the Kuaimian client in its settings.
The exact entry points vary slightly by system version; follow the prompts in your system settings. For install-related issues, see Download and Install the Desktop App.
Recognition and privacy
- Real-time transcription: The interviewer's voice is captured on your machine, uploaded encrypted, and transcribed to text on the server in real time before it enters the answering flow — no local recording is kept.
- Uploaded on demand for recognition: A ⌘E screenshot captures only the current screen and is sent to the server for OCR to read the question and generate an answer from your resume and job — we upload only the content necessary to deliver the feature.

FAQ
Can the interviewer see the floating window? No. The floating window renders only on your local screen, never enters the screen-share stream, and won't appear in recordings.
Will screen / recording software capture it? No — it's excluded from capture at the system level. We recommend testing it once before using it for real.
What if I forget to turn on screen-share stealth? Be sure to enable and self-test it in settings before the interview; if it's off, the window may be shared or recorded into the image.
