AI Agent: capturing, saving and passing on values onto the next node

Describe the problem/error/question

I’m new to n8n and I’m trying to build an AI chatbot. I’m currently testing with Telegram but my question is not specific to a messaging platform (I think). I am using an AI Agent to have a conversational AI-based chat with the user and I want to extract values from the user’s replies (example: what’s your budget?). I want to then pass on those values to the next nodes and use them. I think this is a pretty standard scenario but I don’t know how to do it.

What is the error message (if any)?

Hi @Pedro_Dias,

Welcome to the community :tada:

If you’re new to n8n, searching for similar workflow templates in the templates library might be a good place to start! You can copy them into your instance and customize them as well.

Here are some examples:

I;m looking for this solution too. I need the agent to send a specific value to a specific node connected to it

Solved: n8n actually solves this with $fromAI (so good) and when using tools also passes on the necessary info through the “query” argument. n8n <3
