Turn enterprise data into a knowledge graph
Transform documents and structured data into entities, relationships, and properties mapped to your ontology.
Perseus automates the Text-to-Graph pipeline, turning PDFs, reports, tables, databases, and enterprise data into a structured, queryable knowledge graph built for GraphRAG and AI agents.

99.95% output reliability.

Built around your domain
Every knowledge graph needs a schema.
Start with an ontology generated from your data and use case, or bring your existing ontology. Perseus uses that schema to identify the entities, relationships, properties, and structures that matter to your organization.
As new sources are added, the same semantic model keeps your knowledge graph consistent across documents and systems.


Keep your graph infrastructure
Perseus builds and maintains your knowledge graph. Your graph database stores and queries it.
Use Perseus with the graph infrastructure that fits your architecture, while keeping the knowledge graph portable and available to the rest of your AI stack.
From enterprise data to connected knowledge:
Here's what we offer in four steps:
1. Connect your sources
Bring together PDFs, reports, tables, databases, APIs, and other enterprise data sources.

2. Map entities and relationships
Perseus extracts entities, properties, and relationships and maps them to your ontology, creating a consistent structure across your data.

3. Resolve entities across sources
Identify when information from different documents or systems refers to the same entity. Perseus reconciles duplicates and connects information across sources.

4. Build and maintain your knowledge graph
Perseus assembles the extracted knowledge into a structured graph ready for querying. As your source data changes, affected parts of the graph can be refreshed without rebuilding everything from scratch.

Frequently Asked Questions
Text-to-Graph is the process of transforming unstructured information into structured entities, relationships, and properties represented in a knowledge graph.
Perseus automates this process by mapping information from enterprise data to an ontology and building a connected graph that can be queried by AI applications and agents.
Perseus connects to your source data, extracts entities and relationships, maps them to your ontology, resolves entities across sources, and assembles the results into a structured knowledge graph.
As source data changes, affected parts of the graph can be refreshed without rebuilding the entire knowledge base.
You need a schema that defines the concepts and relationships your knowledge graph should contain.
You can bring an existing ontology or use Perseus to generate one from your source data and business use case before building the graph.
Perseus can connect multiple enterprise sources, including PDFs, databases, APIs, and raw files. This makes it possible to bring structured and unstructured knowledge into the same graph.
Perseus performs entity resolution across connected sources. It identifies records or mentions that refer to the same entity and reconciles them within the knowledge graph.
This helps connect information that would otherwise remain fragmented across documents and systems.
Perseus builds and maintains the knowledge graph by transforming source data into structured entities and relationships.
A graph database stores and queries the resulting graph. Perseus therefore complements graph database infrastructure rather than replacing it.
Yes. The graph can provide structured context for GraphRAG systems and AI agents.
Perseus Graph Retrieval combines graph traversal and semantic retrieval to return entities, relationships, paths, and source references rather than relying only on isolated text chunks.
