memory-agent

Multi-agent AI/CS learning assistant: LangGraph routing, LightRAG graph RAG, three-layer memory, learning roadmaps. FastAPI + React.

Most "RAG demos" stop at retrieve-then-answer. This one goes further: it routes each question to a specialised agent, remembers you across sessions, plans a learning roadmap for a topic, and diagnoses how far you actually got. It also degrades instead of crashing — if the graph database or the embedding API goes down, it falls back to plain LLM or keyword retrieval and tells you so.
