XR + AI Researcher

Building the intelligence layer XR has been missing.

XR resets every session. Apps stay siloed. Intelligence never compounds.

OpenSpatialAI is the infrastructure layer that enables spatial systems to perceive, reason, remember, and adapt — across every session, every environment.

Adaptive Intelligence

Spatial systems that infer intent from behavior, context, and environment — and retain that understanding over time.

OpenSpatialAI

The infrastructure layer for persistent, intelligent XR — systems that remember context, not just render it.

Varun Kumar Siddaraju

XR + AI Researcher

I’m Varun Siddaraju — researcher and the person building OpenSpatialAI. My work is about one problem: making XR systems actually understand what’s happening around them.10 years of research and deployment across education, healthcare, and spatial computing. One published book on Mixed Reality (Apress). Now building the infrastructure to make Spatial AI real.
