Stop losing leads: a 3-node n8n workflow that scores inquiries with GPT and pings you first

Every freelancer I know loses leads in the same quiet way: the message lands, you're heads-down on client work, and by the time you look at it two hours later the person already hired someone else.

You don't need a 27-node lead automation platform. You need one workflow that does exactly three things, in ~10 minutes:

1. Receive the inquiry
2. Score it with GPT (budget fit + readiness)
3. Ping you on Slack with both the raw message and the AI's read on it — so you decide what to send

That's it. No auto-replies, no pretending an LLM is your sales rep. The whole point is that a human approves before anything goes out.

Here's the free workflow, code on GitHub:

What the 3 nodes actually do

1. Lead Webhook — listens on POST /lead. Any form, any site, any tool that can POST JSON gets here: your landing page, a Typeform, an API, whatever.
