AI-Powered RAG Configuration Assistant: From Form to Email Recommendations

This n8n workflow automates the process of generating AI-powered recommendations based on user input from a form and delivering these recommendations via email. It leverages an AI agent to process the input and an OpenRouter Chat Model for generating the responses, making it a powerful tool for providing tailored advice or configurations.

What it does

This workflow streamlines the process of receiving user input and providing intelligent, personalized recommendations:

1. Listens for Form Submissions: The workflow is triggered whenever a user submits data through an n8n form.
2. Processes Input with AI Agent: The submitted form data is fed into an AI Agent, which is configured to use an OpenRouter Chat Model. This agent likely analyzes the input to understand the user's needs or queries.
3. Generates Recommendations: The OpenRouter Chat Model, orchestrated by the AI Agent, generates relevant recommendations or configurations based on the processed user input.
4. Transforms Data: The generated AI response is then processed by an "Edit Fields" (Set) node to extract and structure the necessary information for the email.
5. Conditional Email Sending: An "If" node checks a condition (likely if a recommendation was successfully generated or if certain criteria are met).
6. Merges Data: If the condition is met, a "Merge" node combines the original form input with the AI-generated recommendations.
7. Sends Email with Recommendations: Finally, a Gmail node sends an email containing the AI-powered recommendations to the relevant recipient (e.g., the user who submitted the form or an internal team).

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance to host and execute the workflow.
• n8n Form Trigger: The n8n Form Trigger node is used as the entry point for user submissions.
• OpenRouter Account & API Key: An OpenRouter account with an API key configured for the "OpenRouter Chat Model" node to access their AI models.
• Gmail Account: A Gmail account configured as a credential in n8n for sending emails.

Setup/Usage

1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
2. Configure Credentials:
   • Set up your OpenRouter API Key credential for the "OpenRouter Chat Model" node.
   • Set up your Gmail credential for the "Gmail" node.
3. Configure the n8n Form Trigger:
   • Define the form fields that users will submit. These fields will be the input for your AI agent.
4. Customize AI Agent and Chat Model:
   • Adjust the "AI Agent" node's configuration (e.g., prompt, tools) to suit the specific type of recommendations you want to generate.
   • Select the desired model within the "OpenRouter Chat Model" node.
5. Customize "Edit Fields" (Set) Node:
   • Modify this node to correctly extract and format the AI-generated output into the desired structure for your email.
6. Customize "If" Node:
   • Define the conditions under which an email should be sent (e.g., {{ $json.recommendation !== null }}).
7. Customize Gmail Node:
   • Set the recipient email address, subject, and body of the email. Use expressions to dynamically insert the AI-generated recommendations and original form data into the email content.
8. Activate the Workflow: Once configured, activate the workflow to start processing form submissions and sending recommendations.
