About
Patrivox is a European platform that turns scanned or digital PDF archives into an intelligent, searchable knowledge base. Users upload documents in bulk and the system extracts text with OCR, identifies entities such as people, places, and dates, and enriches metadata automatically. Once processed, archives can be explored through instant full‑text search with typo tolerance, filters (date, type, tags), and semantic search. A built-in AI chat lets users ask questions in natural language and returns answers with exact source citations. Patrivox also creates an interactive knowledge graph that links shared entities across documents, helping users navigate connections and discover relationships. The product emphasizes EU hosting, GDPR-first design, audit logging, and shared access with unlimited readers and multiple administrators.
