The Core Technical Difference
This is the most important thing to understand before comparing features.
Cluely is a browser-based product. Its capture exclusion works within the browser environment — which means it's limited to contexts where you're working inside a browser window.
GhostDesk is a native Windows application that calls SetWindowDisplayAffinity directly — a Windows OS API that tells the Desktop Window Manager (DWM) to exclude a specific window from all capture pipelines. The window is absent from the capture buffer, not just visually hidden. This works above any Windows application: your IDE, terminal, Excel, anything.
This distinction is not marketing language. It's a real architectural difference with practical consequences:
- If you work primarily in a browser, Cluely may be sufficient
- If you work in VS Code, a terminal, Figma, or any non-browser app — GhostDesk is the only option that works
