Xerj Corpus Hub: free, open-source local reference memory for AI agents

Xerj releases Corpus Hub, a free open-source tool under Apache 2.0 that lets AI agents search indexed expert corpora while they work, without retraining.

Xerj describes the tool as "free and OSS forever" and says it runs locally and works with any model, according to Elvis Saravia (@omarsar0). Saravia says installation takes one prompt and that agents can index a project's sources, docs and logs as reference memory.

Santiago (@svpino) describes the same tool as an engine that gives agents indexed content such as source code, engineering guidelines, documentation and security information. He says agents can use that material in tasks such as reviewing an application for vulnerabilities. Both reports repeat Xerj's own description of the tool, and neither reports independent testing.
