What is BrainAPI?
BrainAPI turns unstructured data into a structured knowledge graph, giving AI agents and applications intelligent search, recommendations and contextual memory instead of flat document retrieval.
Pros
- Structured knowledge instead of plain vectors
- Powers search and recommendations
- API-first
Cons
- Graph modelling takes effort
- Needs engineering setup
Who should use BrainAPI
Developers who need agents to remember and reason over connected data.
Who may not need it
Simple apps where basic vector search is enough.
