QueryMind lets you query a real database using plain English. Type a question, get an answer — no SQL knowledge needed.
Built a production-grade AI agent using LangGraph that converts natural language to SQL, executes it on a real PostgreSQL database with 100,000+ rows, and automatically corrects errors in a retry loop if the query fails.
Key features:
7-node LangGraph agent with conditional routing and self-correction
pgvector semantic search for intelligent schema retrieval
Full observability dashboard with real-time metrics and query history
Trace replay — see every step the agent took to answer your question
Deployed live: Next.js frontend on Vercel, FastAPI backend on Render
