# GhostDesk — Private AI Overlay for Windows

> GhostDesk is a native Windows AI productivity tool that floats above any application and is completely invisible during screen sharing. It uses OS-level SetWindowDisplayAffinity (WDA_EXCLUDEFROMCAPTURE) to exclude the overlay from all capture pipelines — Zoom, Teams, Google Meet, OBS, and Windows Game Bar.

## What Makes GhostDesk Different

- **OS-level screen capture exclusion**: Uses `SetWindowDisplayAffinity(WDA_EXCLUDEFROMCAPTURE)` — a Windows kernel API. The overlay is absent from the DWM capture buffer, not just visually hidden.
- **Works above any app**: IDE (VS Code, JetBrains, Cursor), terminal, Excel, browser, anything on Windows.
- **Voice input**: Deepgram Nova-3 with ~300ms streaming latency.
- **Screen OCR**: Auto-captures screen context every 10 seconds via Llama Scout.
- **Deep reasoning**: DeepSeek R1 for coding, architecture, and complex problem-solving.
- **Affordable**: $5 for a 24-hour pass. $9.99/month. No subscription lock-in.
- **Free trial**: 3 days, 10 questions/day, no credit card required.
