About Factagora
Make every claim verifiable.
AI gives you an answer, then throws away when it was true, what it was based on, and who disagreed.
Factagora captures what that compression discards, so every claim can be traced, checked, and trusted.
The Problem
AI answers without knowing when things were true
Contracts get amended, policies get revised, prices change. Search and AI treat every version as equally true and quote whichever they find first, with nothing to show which one is still in force. Factagora keeps the date and the source on every fact, so an answer can say what held on a given day, what replaced it, and exactly where it came from.
What We Value
Truth is built one verified claim at a time
Claim
- Source
- Author
- Timestamp
Every claim comes with receipts
An answer without sources is just an opinion with good posture. Every claim that passes through Factagora keeps its evidence attached: where it came from, who said it, and when it was said.
Confidence you can calibrate
We never ask you to trust the machine. We show the strongest counterargument right next to the supporting evidence, with a confidence score that tells you how much weight the claim can actually carry.

Facts live in time
What was true in 2023 may be false today. Facts in Factagora are versioned and timestamped, so you can see not just what is true, but since when, and exactly what changed.
What We're Building
Verifiable fact infrastructure
Factagora is a verifiable memory layer for AI. One API layer for fact search, claim verification, evidence retrieval, and causal reasoning on top of any LLM, vector DB, or RAG stack. Instead of a single answer, you get the claim, its sources, the strongest counterargument, and how confident you should actually be.
