Tools You’ll Need

n8n.io — Visual workflow automation platform (self-hosted or cloud)

OpenAI — For natural language understanding (via GPT models)

Google Sheets / CRM / Webhooks — Optional, for storing or triggering data

Step-by-Step Setup

1. Collect Leads

Use a form on your website (e.g., Contact Form, Typeform, or Webflow) to capture:

Name, Email, Company, Message / Use Case, Send this data to a webhook node in n8n.

2. Send Data to OpenAI

Use n8n’s HTTP Request node to call the OpenAI API. Prompt example:

Evaluate the following lead message and return whether it's a high-quality lead. Consider business need, clarity, and interest level:

"{{message_from_user}}"

Respond with: Qualified or Not Qualified.

3. Process the AI Output

Use a switch or IF node in n8n to act on OpenAI’s response:

Qualified: Send to CRM, notify sales team, or tag as “hot lead”

Not Qualified: Archive or send a polite rejection email

Optional: Add a Google Sheets or Airtable node to log each lead, decision, and timestamp for later analysis.
