How Blue works

RAG
  • Upload documents
    Store PDFs and manage them in one place.
  • Index & retrieve
    Chunks are embedded and searched to find relevant context.
  • Ask questions
    Blue answers using your documents + conversation history.

Tip: Keep filenames short and meaningful. Blue performs best when documents are clean and readable.

Built with FastAPI + PostgreSQL + FAISS + Next.js
