GhostDesk

GhostDesk is a Windows desktop AI assistant that floats above every application as a private overlay, invisible to screen capture, recordings, and video calls. It uses OS-level APIs (SetWindowDisplayAffinity) to exclude itself from all screen-capture pipelines, meaning tools like Zoom, Teams, OBS, and Windows Game Bar simply won't see it. Built-in AI requires no API keys or configuration — just install, set your hotkeys, and start asking questions.

• Always-on-top overlay — Floats above browsers, IDEs, terminals, and design tools; switches between a minimal taskbar and a full chat panel.
• Screen-share invisible — Uses native Windows APIs to exclude the overlay from all screen capture, verified daily across 14+ platforms including Zoom, Teams, Google Meet, Slack, and Discord.
• Built-in AI chat — Free plan uses Llama 3.3 70B via Groq; paid plans upgrade to GPT-4o via OpenAI. No API keys or accounts needed.
• Voice mode — Click the mic icon to speak naturally; smart silence detection filters background noise and transcribes via Deepgram Nova-3 (free) or OpenAI Whisper (paid).
• Screen analysis / vision AI — Select any region of your screen; GhostDesk reads code, documents, diagrams, charts, and UI, then explains or analyzes them instantly.
• Streaming & context-aware responses — Answers stream token-by-token; conversation context is maintained within a session for natural follow-up questions.
• Keyboard-native controls — Global shortcuts toggle visibility, enable click-through mode, or quit — all fully customizable in settings, working even without focus.
• Invisible in Task Manager & taskbar — Runs silently with no icon in the taskbar, Alt+Tab, or process list.
• Quick setup — Download the lightweight installer, run it (no admin required), and be up and running in under a minute with no dependencies.
