VectorlessDB RAG

The Experiment: What Is 'Vectorless RAG'?

No vector database. No embedding model. No infrastructure beyond a single serverless function. I built this on Cloudflare Workers with React Router 7 and TypeScript. The app lets you upload PDFs, ask natural language questions, and get structured answers back — all running at the edge for pennies per month.
