Distributed Utility Discovery Engine: Powers our privacy-first AI. DUDE routes spine detection, OCR text extraction, and semantic search locally or to sovereign nodes without handing private data to big-tech clouds.
Find books by themes, mood, and topics across multiple languages using DUDE-generated vector embeddings alongside standard catalog search.
The current beta focuses on dependable book-box CRUD and search. The longer-term vision is to let independently operated nodes connect through shared OpenAPI contracts.
How nodes connect and share data across the network
The OpenAPI contracts and app-agnostic DUDE boundary are designed to support independent nodes later
