About this app
Utopia is a self-hosted knowledge platform designed around temporal awareness, utilizing a knowledge graph that remembers when each fact was true. It features hybrid retrieval combining Tantivy full-text search and pgvector embeddings, inline citations, document ingestion for various file formats, web scraping, multi-tenant workspace management, and a review queue for extracted facts. Built with Rust and PostgreSQL, it runs as a single binary and supports OpenAI-compatible LLM endpoints for fully air-gapped deployments.
