Built an AI-powered app that lets users upload a PDF or paste a URL and ask questions about the content. The app answers strictly from the document — never from general knowledge — and cites the exact page numbers behind every answer.

Implemented a full RAG (Retrieval Augmented Generation) pipeline: documents are split into chunks, converted into vector embeddings, and stored in a local Chroma database. At query time, the most relevant chunks are retrieved and passed to an LLM to generate a grounded, source-backed response.
