Knowledge Universe unifies 14 sources for RAG

Knowledge Universe is an open-source FastAPI API that queries a wide spread of knowledge sources in parallel, scores the results, and returns them directly as LangChain Documents or LlamaIndex-ready outputs. It is pitched as a missing ingestion layer for RAG builders who are tired of hand-rolling crawlers for every project.

// ANALYSIS

This is a smart attack on the least glamorous part of RAG: getting decent source material into the pipeline before retrieval even starts.

–The real pitch is not just aggregation but standardization: one interface over arXiv, GitHub, Wikipedia, StackOverflow, Hugging Face, and other sources
–Returning LangChain and LlamaIndex-friendly objects directly makes it more useful to practitioners than a generic search API
–Local reranking with sentence-transformers and no OpenAI dependency gives it a strong cost and privacy story for hobbyists and self-hosted teams
–The repo still looks early, with low GitHub traction and no published releases, so the idea is ahead of proof that it can become a dependable production layer
