View integration guideWhere it fits
Add one trust layer. Keep your stack.
Factagora drops in on top of the LLM, vector DB, and RAG pipeline you already run — and grounds every answer in facts you can trust.
Answers that are current
Point-in-time facts mean your AI sees what was true at the moment that matters — no stale data, no hindsight bias.
Answers with a reason
Causal links explain why something happened, not just that it did — so AI can reason, not just retrieve.
Answers you can trace
Every fact carries its source and a confidence score, so each answer is backed by evidence you can follow.
Answers you can audit
A verifiable, traceable trail for the work that can't be wrong — finance, legal, healthcare, and compliance.
