Hi guys I was wondering if someone can help me. I have been looking into building an ai agent and app for my business. What would you suggest is better Crew AI or N8N. I have some experience in coding and understand the basics of using both crew ai and N8N. However I am starting to struggle with getting them working correctly. I have started creating a couple ai agents that reads pdf files and answer questions. I am stuck on how to integrate data sheets to help the agents knowledge so it can be more precise. Is anyone able to help me thanks
