# Evidence Library: manage product, topic, and source evidence

> HaloX Evidence Library manages products, topics, claims, keywords, and sources so Content Factory and citation workflows can use verified evidence.

## What is this feature?

**Evidence Library** is an independent Pro-mode `Misc` feature. Personas define voice; Evidence Library manages the product, topic, claim, keyword, and source evidence AI answers and content outputs rely on.

*Evidence Library becomes useful when claims, keywords, and sources flow into the Content Factory evidence check. Use this evidence view to see whether a draft has enough trusted sources before it becomes citation-ready content.*
