AI Coding Assistant for Technical Interviews

GhostDesk is a native Windows AI overlay that is completely invisible during screen shares. It floats above your coding environment — CoderPad, HackerRank, VS Code, or any browser-based editor — and gives you access to DeepSeek R1 reasoning, screen OCR, and voice input while the interviewer sees nothing.

The invisibility uses Windows SetWindowDisplayAffinity (WDA_EXCLUDEFROMCAPTURE) — an OS-level API that removes GhostDesk from the capture buffer entirely. It is not a visual trick. The window does not exist in the data Zoom, Teams, or Meet receives.

Invisible on screen share

GhostDesk uses Windows SetWindowDisplayAffinity (WDA_EXCLUDEFROMCAPTURE) to be completely excluded from all screen capture APIs. The interviewer sharing their Zoom call or CoderPad session cannot see GhostDesk at any point.

DeepSeek R1 for hard problems

Technical interviews favor reasoning-heavy questions — system design, dynamic programming, graph algorithms. GhostDesk routes these to DeepSeek R1, a model that shows its reasoning chain so you can follow and explain the approach in your own words.

Screen OCR — reads your coding environment

GhostDesk automatically captures your screen every 10 seconds via Llama Scout OCR. It reads whatever is in your coding environment — the problem statement, your current code, error messages — so you can ask questions in plain English without copy-pasting.

Voice input at ~300ms latency

Speak your question instead of typing it. Deepgram Nova-3 transcribes at ~300ms latency, so you can ask for help quickly without your keystrokes being visible to the interviewer.

Works above any coding environment

Whether your interview uses CoderPad, HackerRank, LeetCode, a shared VS Code session, or a plain browser-based editor — GhostDesk floats above it all and stays invisible. It is not limited to any specific platform.

Pricing for interview use

The free tier gives you 10 queries/day — enough for light preparation. For an actual interview day, the 24-hour pass (₹250 India / $10 internationally) gives unlimited queries with no monthly commitment.

Frequently Asked Questions

Can the interviewer see GhostDesk during a technical interview?

No. GhostDesk uses Windows SetWindowDisplayAffinity (WDA_EXCLUDEFROMCAPTURE) to be completely excluded from all screen capture APIs. It does not appear in Zoom recordings or any screen-sharing software the interviewer uses.

Does GhostDesk work with CoderPad and HackerRank?

Yes. GhostDesk floats above any Windows application including Chrome (where CoderPad and HackerRank run), VS Code, and any other coding environment. The screen OCR automatically reads whatever is on your screen.

How do I verify GhostDesk is invisible before my interview?

Open OBS Studio or Windows Game Bar (Win+G), start a screen capture, then open GhostDesk. You will not see GhostDesk in the capture preview. This is the same mechanism Zoom uses — if OBS can't see it, Zoom can't either.

Is GhostDesk free for interview use?

Yes. The free tier gives you 10 AI queries per day. For a single high-stakes interview day, the 24-hour pass (₹250 India / $10 internationally) gives you unlimited queries.

Which Windows versions does GhostDesk support?

Windows 10 (build 19041, May 2020 Update or later) and Windows 11. The SetWindowDisplayAffinity capture exclusion API requires this minimum version.
