Feature Comparison
Patrivox
Next-Generation AI Processing
Patrivox utilizes cutting-edge Mistral AI to perform more than just basic text recognition. It automatically processes batch uploads of hundreds of PDFs, extracting text with high accuracy, identifying and classifying named entities (people, places, organizations, dates), and enriching document metadata. This foundational feature eliminates manual data entry and configuration, creating a rich, structured dataset from unstructured documents in minutes, forming the basis for all powerful search and discovery tools.
Intelligent Search & AI Chat
Move beyond simple keyword matching. The platform offers instant full-text search across the entire collection with built-in typo tolerance. For deeper inquiry, users can ask complex questions in plain language through an AI chat interface. The AI synthesizes information from across the documents to provide concise answers, always citing the exact source pages for verification and further exploration, creating a seamless loop of question and discovery.
Interactive Knowledge Graph (Constellation)
This feature visually uncovers the hidden narratives within your archives. Every entity extracted by the AI is automatically linked across documents, forming an interactive web of connections called "Constellation." Users can navigate from person to place to organization, discovering relationships and contextual links that were previously obscured, enabling novel research insights and a holistic view of the archival content.
Sovereign European Hosting & Sharing
Built with European data sovereignty as a core principle, Patrivox is GDPR-native and hosted exclusively on European servers. It includes robust audit logs for transparency.
