I want to create a solution that will fill out a standardized template with information. It will need to search the web for information related to each section as well as pull some info from a vector db that I can load. The output should be saved. Any ideas on how I can get started??? Either crewai or langchain/langgraph or both. You tell me bc I have no clue right now but I am actively researching and learning. Any help would be greatly appreciated!
