GhostDesk is a free AI overlay assistant for Windows that floats above any app and stays invisible during screen shares, Zoom calls, and recordings. No tab switching, no distraction — powered by Llama and GPT-4.1.
GhostDesk is a Windows AI overlay that sits on top of any meeting or interview — and is completely invisible to screen share, OBS, and recording software.
It transcribes both sides of the conversation in real time using Deepgram Nova-3, then feeds context to GPT-4.1 and Llama 4 Scout to surface relevant answers, talking points, and suggestions — all without the other party ever seeing it.
Built for:
Software engineers in technical interviews
Professionals in high-stakes sales calls or client meetings
Anyone who wants an AI co-pilot without the awkwardness of alt-tabbing
The 'invisible to screenshare' feature isn't just a nice-to-have in certain markets; it's a cultural necessity. In MENA enterprise environments, particularly GCC countries, there's an unspoken professional standard where displaying AI assistance tools during client meetings can signal inexperience or lack of mastery. I've seen sales teams and consultants manually turn off Otter/Fireflies before screensharing despite needing the support. GhostDesk's architecture solves a legitimately different problem than standard meeting AI tools.
As someone who's had to awkwardly pause screenshares to search docs mid-call, the invisible overlay concept is brilliant. Being able to silently pull up relevant client data or talking points without breaking flow would save me from those "let me just..." moments that kill momentum.

@mit_parikh Congratulations on this! I really resonate with the no tab switching. Curious how GhostDesk handles heavy accents or fast speakers? Would love to know what your real-world WER looks like in noisy call environments.
Congrats @mit_parikh I appreciate the ease and accessibility of this! Does GhostDesk support custom knowledge bases? For example, could I feed it my product docs, or research notes so it surfaces my specific answers rather than generic GPT responses?
