Knowledge workers and developers often need real‑time AI assistance while using desktop applications, but existing AI overlays appear in screen captures, video calls, and recordings. This exposure forces users to switch contexts or disable the assistant, breaking workflow and risking the leakage of private notes or code snippets.

GhostDesk delivers a native Windows overlay that stays permanently on top of any application while remaining invisible to screen‑capture pipelines, the task manager, and the taskbar. By leveraging the Windows SetWindowDisplayAffinity API, the overlay is excluded from all video‑conferencing, streaming, and screenshot tools, ensuring that only the user sees the AI interface. Users invoke the assistant via global hotkeys, speak naturally to trigger voice transcription, or capture screen regions for on‑the‑fly vision analysis. The backend routes queries to Llama‑based large language models (or GPT‑4o on paid plans) and streams token‑by‑token responses, preserving conversational context across turns. All interactions are encrypted end‑to‑end and require no external API keys, allowing uninterrupted, private assistance across IDEs, browsers, design tools, and terminal windows.

OS‑level invisibility using SetWindowDisplayAffinity, preventing the overlay from appearing in Zoom, Teams, OBS, or any screen‑recording software.

Always‑on‑top, click‑through window that does not capture focus or appear in Alt‑Tab/taskbar listings.

Global keyboard shortcuts (customizable) for toggling visibility, enabling click‑through mode, and quick quit.

Voice activation with built‑in silence detection, powered by Deepgram Nova‑3 (free) or Whisper (paid), eliminating wake‑word requirements.

Integrated vision AI that processes user‑selected screen regions, using Llama 4 Scout for code, document, and diagram analysis.

Context‑aware chat powered by Llama 3.3 70B (free) or GPT‑4o (paid), with token‑streaming responses for low‑latency feedback.

End‑to‑end encryption and role‑based access controls for all data transmitted to the cloud analytics service.

Single‑installer package with no external runtimes; compatible with Windows 10 build 19041+ and Windows 11.

All features included in every pricing tier; no separate add‑ons required.

The primary users are software developers, data analysts, and remote knowledge workers who need AI assistance during screen‑sharing sessions, as well as IT administrators seeking a privacy‑preserving productivity overlay for enterprise desktops.

GhostDesk offers a free tier and paid subscriptions: $15 per month, $12 per month (billed annually for a 3‑month commitment), $9 per month (billed annually for a 6‑month commitment), and a one‑time $99 lifetime license. All plans include the full feature set.
