More
Your documents know more than you think.
PaperOffice AI automatically discovers 10+ relationship types between your documents: invoice chains, contract links, supplier networks, payment references – all without any configuration. Combined with 12 entity types and 4096-dimensional embeddings.
From document to knowledge network
Upload
Upload documents or connect storage mounts. New documents are automatically taken into the processing pipeline.
Entity Extraction
AI extracts 12 entity types: companies, persons, locations, amounts, IBANs, dates, products, emails, phone numbers, invoice & contract numbers.
Relationship Discovery
Embedding similarity, meta-field analysis and LLM reasoning discover relationships: invoice_for, order_for, delivery_for, contract_with and more.
Entity Resolution
Different spellings of the same company or person are automatically unified into canonical entities. Embedding + string similarity clustering.
Graph Construction
Documents and entities become nodes, relations become edges. An interactive Knowledge Graph emerges — navigable and traceable.
Graph-RAG Search
Natural language queries traverse the graph: vector search + fulltext + graph expansion. Multi-hop reasoning across relationships.
Enterprise Knowledge Discovery
Semantic Search
Find documents by meaning, not just keywords. Natural language queries with source citations across your entire archive.
Automatic Connections
AI discovers invoice references, contract links, customer mentions and supplier networks. Transaction chains visualized: Order → Delivery → Invoice.
Graph-RAG Answers
Ask questions about your documents and get accurate, sourced answers. Multi-hop reasoning: SUM, COUNT, LIST, COMPARE, SUMMARIZE and more.
Entity Resolution
Automatic identification and linking of companies, persons and accounts across all documents – even with different spellings. Canonical entity clustering.
Visual Recognition
Find documents by logo, letterhead or visual elements. Image embeddings (2048-dim.) identify senders across your entire archive.
Interactive Visualization
Interactive graph with document thumbnails as nodes. Hover for details, click for preview, double-click to open. Color-coded edges by relation type.
