AutoRAG alternatives

Marker-Inc-Korea/AutoRAG (5.4k stars, +157 this week): Your Personal Librarian Agent. Ask anything on your computer, organize files, remember important info and files.

Below are 9 other RAG / vector repos tracked by OSS Radar that share at least two GitHub topics about what they do with AutoRAG (platform, language and framework tags don't count), ordered by how closely their topics overlap (rarer shared topics count more), then by stars gained in the last 7 days. Topic overlap means a similar problem space, not a drop-in replacement, so check each project's README.
