Turn any data into a living knowledge graph

Ingest any data source. Get a knowledge graph that auto-enriches itself. Ask questions that SQL and RAG simply can't answer.

Cograph Intelligence

Which patients on Metformin also developed renal complications and were treated by doctors who reported adverse events with Lisinopril?

3 patients found

Crossed 4 data sources: EHR records → prescription history → adverse event reports → physician case logs. SQL would require 6+ joins across siloed databases.

The architecture decisions that make Cograph possible.

Living Knowledge, Not Snapshots

Attach functions to entity types that auto-enrich and refresh your data on schedule. Commodity prices update daily. Company financials refresh quarterly. Your knowledge graph stays current without manual intervention.

Join Your Data With the World

Your private procurement data automatically connects with public market trends, industry benchmarks, and supplier intelligence through a shared ontology. Every new dataset makes every existing dataset more valuable.

Drop a CSV. Ask Questions. That's It.

No schema design. No data modeling. No configuration files. Cograph auto-infers entity types, attributes, and relationships from your raw data. Production-ready knowledge graph in seconds.

Exact Answers, Not Approximations

SPARQL computes over the complete dataset. COUNT returns the real count. AVG computes from every row. Multi-hop joins traverse actual entity relationships. No retrieval sampling, no hallucination.

Agent Ready

Easily connect with your AI agents

Python SDK, REST API, or MCP — pick your path. Integrate in minutes.

Get started in 3 lines

from cograph import Client

client = Client(api_key="your-key")
client.ingest("sales_data.csv", kg="my-data")
answer = client.ask("What's the average deal size by region?")
print(answer)  # "$47,500 across 12 regions"

One-line agent integration

CLI

Ingest any CSV and start querying in seconds.

npx cograph ingest data.csv --kg my-data
MCP

Connect any MCP-compatible agent to your knowledge graph.
