Products and solutions
Fact Checker API, Fact Search API, Evidence Finder API, DeepVerify browser extension, DeepStamp extension, FactBlocks knowledge-graph technology.

Uses a temporal knowledge graph (FactBlocks) rather than a vector store alone, enabling claim verification with confidence scores and source citations, applicable in real time to any LLM output.
Target customer
Enterprises deploying generative AI in high-stakes domains — law firms, financial institutions, and ESG/compliance teams — plus developers building AI products needing trust infrastructure.
Industries served
Legal, Financial Services, ESG/Compliance, Enterprise AI/SaaS
Technology advantage
Proprietary Temporal Knowledge Graph (TKG) structuring of documents into verifiable 'FactBlocks', proven at scale (350,000+ legal documents restructured for Shin & Kim).
How they differentiate
Focused on claim-level, source-cited fact verification via a temporal knowledge graph rather than generic RAG evaluation, with proven enterprise pilots in legal (Shin & Kim) and finance verticals ahead of a 2026 North America/Europe push.
