Invisible AI Overlay for Zoom Meetings

GhostDesk is a Windows AI overlay that is completely invisible during Zoom screen shares. Ask questions, get real-time AI assistance, and use voice input — all while sharing your screen. Your colleagues see nothing.

The invisibility uses Windows SetWindowDisplayAffinity (WDA_EXCLUDEFROMCAPTURE) — an OS-level API that removes GhostDesk from the capture buffer before Zoom ever sees it. The window is genuinely absent from the capture data, not visually hidden.

How to verify it's invisible — before your call

  1. Open OBS Studio (free) or Windows Game Bar (Win+G)
  2. Start a screen capture or recording
  3. Open GhostDesk
  4. Check the capture preview — GhostDesk will not appear
  5. Zoom uses the same capture pipeline as OBS. If OBS can't see it, Zoom can't either.

What GhostDesk does during a Zoom call

  • ✅ Answers questions via DeepSeek V3 (chat) and DeepSeek R1 (reasoning)
  • ✅ Reads your screen via OCR every 10 seconds — no copy-pasting needed
  • ✅ Transcribes voice at ~300ms latency via Deepgram Nova-3
  • ✅ Invisible on Zoom screen share, recording, and spotlight view
  • ✅ Works above any Windows app — IDE, browser, Excel, anything
  • ❌ Does not work on macOS (Windows 10/11 only)

Frequently Asked Questions

Does GhostDesk appear on Zoom screen share?

No. GhostDesk uses Windows SetWindowDisplayAffinity (WDA_EXCLUDEFROMCAPTURE) — an OS-level API that removes GhostDesk from the capture pipeline. Zoom's screen capture never receives GhostDesk pixels.

Does GhostDesk appear in Zoom recordings?

No. Zoom recordings use the same capture pipeline as live screen share. GhostDesk is excluded at the OS level and does not appear in recordings either.

Can I use GhostDesk while sharing my full desktop on Zoom?

Yes. The capture exclusion is per-window at the DWM level — it works for full desktop sharing, window sharing, and application sharing.

Does it work with Zoom on Windows 10?

Yes, on Windows 10 build 19041 (May 2020 Update) and later. The WDA_EXCLUDEFROMCAPTURE flag requires this minimum build.

Is GhostDesk free for Zoom use?

Yes. The free tier gives 10 AI queries per day with no credit card required. Paid plans start at ₹250/$10 for a 24-hour pass.
