Hi guys
I'm looking to build an app that uses a PDF as a knowledge base and allows users to upload additional PDFs. The goal is for the app to provide responses based on the combined content of these PDFs. The documents are quite long (around 100 pages) and are in Polish.
I attempted to use the OpenAI Playground to upload PDFs for Assistants, but it failed miserably. I'm new to AI and unsure whether to use something like LangChain or another tool. I came across tools like Upstage, which seems to be a bit better.
I know how to code and will manage to follow any stack needed. Could anyone suggest what tools or frameworks I should use to build this app?
Thanks!
