Built-in Vector Store node with semantic search, document insert/retrieve, and AI Agent tool modes for RAG.
Milvus stores and searches AI-generated vectors, which powers things like semantic search (finding results by meaning, not just keywords), chatbot memory, and recommendation engines. It's the behind-the-scenes engine that makes AI apps remember and find information quickly.

Milvus is best for small businesses that are building AI-powered apps and have a developer on staff who can set things up and maintain it. The biggest plus is that it's free to self-host and handles AI search tasks really well. The catch is that this is a technical infrastructure tool — if you don't have someone comfortable with databases and code, it will feel overwhelming fast.
