My 10-Node Agentic RAG Architecture: Combining LangGraph, Cohere, Pinecone & MCP for Dense Legal Parsing
Built an 11-node LangGraph RAG for Indian legal & financial documents — with PII masking, jailbreak detection, tool calling, and hallucination checks
LangGraph was right about agents all along, we just needed 3 years to catch up

Tested 5 web search APIs so you don't have to (full data + tables inside)
We're looking for developers interested in solving one of the hardest problems in AI agents: memory.
30+ officially free AI/ML books, all in one curated repo
Anyone else feel like LangChain is amazing for a demo, but a nightmare for production?
