Hacker NewsA friend and I built a browser prototype that answers questions about whatever’s on your screen using getDisplayMedia, client-side wake-word detection, and server-side multimodal inference.
Hard parts:
– Getting the model to point to specific UI elements
– Keeping it coherent across multi-step workflows (“Help me create a sword in Tinkercad”)
– Preventing the infinite mirror effect and confusion between window vs full-screen sharing
– Keeping voice → screenshot → inference → voice latency low enough to feel conversational
We packaged it as “Clippy” for fun, but the real experiment is letting a model tool-call fresh screenshots to help it gather more context.
One practical use case is remote tech support — I'm sending this to my mom next time she calls instead of screen sharing.
Curious what breaks.
