Could you build this?
Partial A browser-based slide viewer with shared cursors and a pen is buildable, but real-time multi-user sync and PDF/PPTX rendering at reliable quality add infrastructure and conversion complexity that a quick vibe-coded build will struggle with.
What it would actually take: Use pdf.js or a server-side converter for slide rendering, and a real-time layer like Liveblocks, PartyKit, or a WebSocket server with presence and state sync for shared control and ink. Reliable PowerPoint fidelity and low-latency sync across many users are the hard parts, requiring distributed-systems and document-conversion experience.
