Automate AI Prompt Injection from Form Input in n8n

Yes, it is possible! You can automate this by linking the prompt value from a form (or any previous node) to the AI node’s prompt parameter. Instead of manually defining the prompt, you can use the option where the node “takes the prompt from a previous node automatically.”

How to Configure

1. Pass the Prompt from Your Form:
   Ensure that the node receiving the form input outputs a field with the prompt text. By default, the AI node expects this field to be named chatInput.

2. Rename or Set the Field if Needed:
   If your form node outputs a field with a different name, use an Edit Fields (Set) node to rename or map that field to chatInput.

3. Configure the AI Node:
   In the node where you are setting up the AI query, choose the Take from previous node automatically option for the prompt. This configuration tells the AI node to automatically use the incoming chatInput field as the prompt.

    B --> C[AI Node (with 'Take from previous node automatically' selected)]

By following these steps, the prompt entered in your form will be automatically passed to the JavaScript ask AI parameter without the need for manual intervention. Let me know if you need further details on any step!
