The r/RAG subreddit is one of the reasons we started Needle as a RAG API in the first place.
It’s one of the few places online where people share what actually works. Not theory, not marketing. Just real builders figuring things out together.
The problem? Once a discussion scrolls past, it’s basically gone. And Reddit search is... Reddit search.
So we built a free tool that lets anyone explore everything discussed in r/RAG in 2025.
Who this is for:
Devs looking for RAG implementation advice (chunking strategies, embedding models, retrieval approaches)
Business people trying to understand how RAG can actually help their company
Founders researching what problems and patterns keep coming up
What you can learn:
The r/RAG community has figured out a lot of stuff the hard way. Things like:
Which embedding models actually perform well in production
When to use hybrid search vs pure vector search
How to handle chunking for different document types
What retrieval strategies work for specific use cases
All of this is now searchable in one place.
How it works:
It’s an agentic chat that searches through a full year of r/RAG posts and comments. Ask a question, get answers grounded in real community discussions with sources linked.
No signup, completely free.
