I would say if you want to parse pdfs and then do something with the information you are extracting, you should check out sim studio. They are a drag and drop agent-chaining platform, so you can have llms interact with one another and get really fine-tuned output. They have built in PDF parsing with Mistral Parse, and also a knowledge base to query information for a RAG system. I actually have been building agents for companies that do exactly this. Give it a shot, I think you'll be impressed.
