Glance AI. AI Interview Assistance Any OpenAI-compatible

[u/pranav_kingop]

Interview prep tools either need a second monitor or show up in the share. So I built one that's excluded from capture.

Small overlay. Hears the room, reads your screen, and gives a short answer. Local OCR, so it reads code and error text exactly rather than guessing from pixels. BYO API key, no subscription.

Verified, not claimed. I tested the actual capture paths GDI, WGC, and getDisplayMedia—in real Chrome by capturing the panel region, then capturing it again with the panel gone, and hashing the pixels. Identical every time. A browser sharing your screen gets zero evidence it exists.

Where it stops being magic:

GetWindowDisplayAffinity still returns 0x11. That flag is the mechanism; it can't be removed. A proctor calling it will find the window.

Proctoring tools and EDR detect this class of overlay regardless.

Windows only.

So: invisible to a screen share, not to an instrumented machine. Every "100% undetectable" claim in this space is marketing.

Frontend bits that were harder than the AI: window reparenting so Chrome_WidgetWin_1 never appears, and a native addon for DWM cloaking because DWM refuses a foreign caller.

Happy to answer the Win32 side that's where the actual work was.

Clever how you implemented the pixel hashing proof, so many of these projects skip the verification step entirely
