AI that knows
exactly where you are.
The Local AI Platform runs the open-source Gemma 4 model entirely on device via LiteRT — grounded in real-time sub-meter positioning and ZephrTiles place context through on-device RAG. The model is optimized for tool and function calling, enabling it to query your surroundings and navigate without a cloud dependency.
No cloud dependency means your position, surroundings, and queries never leave the device — a first for location-aware AI.
Gemma 4 via LiteRT
Open-source Gemma 4 running on-device via LiteRT — optimized for tool calling and grounded via ZephrTiles RAG embeddings
ZephrTiles Context
Offline spatial place data bundled with the model for instant local awareness
Privacy-first
Your position and queries never leave the device — ever
Works offline
Full spatial AI capabilities with zero network dependency
Built on Zephr's spatial foundation
The Local AI Platform sits on top of everything Zephr has already built — combining positioning precision with grounding richness into a single on-device experience.
Precise Positioning
Sub-meter GNSS positioning and 6DoF orientation tells the model exactly where you are and what you're looking at.
Places Grounding
ZephrTiles packages rich Overture Maps place data for offline use — the model's window into the physical world.
Local AI Model
An on-device LLM queries positioning and grounding in real time to answer spatial questions without any cloud call.
Coming SoonWhat on-device spatial AI enables
Offline navigation
Complete turn-by-turn guidance with landmark awareness in areas with no connectivity.
Spatial Q&A
Answer "what's around me?" queries with full place awareness, zero network latency, zero data egress.
AR assistants
Power next-gen AR experiences where the AI knows precisely where the user is and what they're looking at.
Field intelligence
GIS professionals and field teams with context-aware AI that works underground, indoors, or in remote areas.
Secure deployments
Defense and enterprise use cases where no data can leave the device under any circumstances.
Real-time agents
Spatial agents that act on live positioning data without the latency of a cloud round-trip.
