I was trying to extract characters in a novel. I used an iterator with a llm in it to handle each chapter step by step, but I wanted to use the output of the previous iteration in the prompt of the next iteration, since it should know who has appeared in previous chapters.
How can I do it?

I was also looking for this functionality, and invested some time without any success. The solution is pretty easy. In fact you have two options. For both you need to use the Chatflow type application.

1. You can "enable memory" in the LLM block and you can also set the window size.
2. You can use the Conversation Variables.
