A small web app that reads PDFs and answers questions with inline citations. Built to learn RAG pipelines end-to-end.
Noesis is a web interface for reading academic and technical PDFs. You upload a document, it extracts and embeds the text, and then you can ask questions about it — answers come back with the exact paragraph they were drawn from.
I spend a lot of time reading papers for class and it felt natural to build a small tool that would help me triangulate between a dozen tabs. Keeping it grounded in citations was the whole point — I don't want an assistant that hallucinates when I'm trying to learn.
Embeddings, vector stores, chunking strategies, and how brittle RAG can be without good source-grounding. Also: the front-end is half the product — a well-designed reading surface changes how the tool feels entirely.
