Troubleshooting
Causes and fixes for frequent issues — desktop permissions, system audio, screen-share stealth, transcription, credit sync, and installation.
This page gathers the most common issues you'll run into using Kuaimian, with causes and fixes by scenario. Most desktop issues stem from ungranted system permissions, so starting with permissions is usually the fastest path. Still stuck? Reach out to us via the methods at the bottom of the page.
Desktop: permissions
Interview Copilot relies on system-level screen and audio capabilities and won't work without permissions. For the steps to grant them and platform differences, see Screen-Share Stealth and Permission Setup.
| Symptom | Cause | Fix |
|---|---|---|
| Prompted to grant screen-share / recording permission | Screen recording permission not granted | macOS: System Settings → Privacy & Security → Screen Recording, check Kuaimian, then restart the app to take effect |
| Can't hear / recognize the interviewer's voice | System audio capture permission not granted | Grant audio / microphone permissions in System Settings; confirm the interview software is playing system sound out loud rather than only through a private headphone channel |
| Still not working after authorizing | Permission change not reloaded | Fully quit and reopen the desktop app; on macOS, the app must be restarted after changing screen recording permission |
Desktop: can't hear the interviewer's voice
Interview Copilot recognizes questions by capturing system audio, not by picking up ambient sound through the mic. If it can't recognize:
- Confirm system audio capture permission is granted.
- Confirm the interviewer's voice is actually playing from your machine's system (system volume isn't 0 and isn't muted).
- Some meeting apps may exclusively claim the audio device — first make sure the interview sound plays out loud normally, then start the copilot.
Desktop: worried the floating window can be seen
The assist floating window is invisible to screen sharing / recording, so under normal conditions the other side can't see it. If you're not sure:
- Confirm "screen-share stealth" is enabled in settings.
- Start a test share once before the real interview and confirm for yourself that the assist window doesn't appear in the shared image.
For how it works, see Screen-Share Stealth and Permission Setup.
Desktop: no recognition / no transcription
- Check that both screen-share and system audio permissions are granted.
- Transcription triggers an answer only after a complete question is recognized; sentences that are too short or get interrupted may produce no result.
- For questions that require answering by reading the screen (live coding, system design, questions in a shared document), use ⌘E (the default; customizable in settings) to screenshot and feed the question — see Coding-Test Assist.
Login / credits out of sync
One account works across all three platforms, with credits shared across devices. If the display is inconsistent:
- Confirm you're logged into the same account on each platform.
- Not refreshed after a top-up or consumption: re-enter the page or restart the app, and credits will be re-fetched.
- Still inconsistent, or a top-up hasn't been credited: check the payment order status and contact us if needed. For credit rules, see Account, Credits, and Top-ups.
Download / install failures
- Get the installer from the official Download and Install the Desktop App page and install it following the steps for your system.
- macOS reports an unknown source / can't open: follow the steps in the install docs to allow it in System Settings.
- Installer download interrupted: re-download and make sure your network is stable.
Web page issues
- Page displays abnormally or doesn't respond: refresh the page; if needed, clear the browser cache and log in again.
- We recommend a recent version of a modern browser such as Chrome / Edge.
- AI Resume and mock interviews work right in the browser with no install; Interview Copilot is a desktop-only capability and isn't available on Web.
Still stuck?
- Permissions and stealth: Screen-Share Stealth and Permission Setup
- Installation: Download and Install the Desktop App
- Account and credits: Account, Credits, and Top-ups
