🎯 What you will build

A one-form tool that audits any landing page with AI. You paste a URL, the workflow downloads the page, and an OpenAI agent returns a friendly roast of the page plus a numbered list of conversion optimization tips tailored to that exact page.

This course lets you rebuild the workflow node by node, live, without opening the original. Every value is copy-paste ready.

Who it's for: SaaS founders, marketers/growth teams, and e-commerce/lead-gen businesses who want more conversions from the traffic they already have.

<aside> ⏱️

Total build time: about 10 minutes. Only one account is required: OpenAI. Everything else runs on built-in n8n nodes (no community nodes).
