Premium guide for paid subscribers

When I published the story of building AI Advent Challenge, the most common question wasn’t “how did you do it?” It was “can you show me EXACTLY what you asked the AI?”

This guide is that answer. Not theory. Not generic advice. The actual prompts, the real conversations, the specific strategies that turned $50 and 30 days into a platform with 507 active users.

By the end, you will have a replicable framework for validating and developing your own idea using AI tools. Of course, this will be done without wasting credits, time, or sanity!

What You’ll Actually Get

  • The exact AI conversation that validated this idea in under 1 hour (not “do research,” but the actual prompts)

  • The Lovable prompts that worked (and the ones that burned credits)

  • The credit-saving framework that kept me under $50

  • The “fireproof” prompting system that prevents AI from destroying your work

  • Step-by-step replication guide you can follow for your own project

  • 🎁 A deeper technical guide of the AI Advent Challenge from Lovable

Let’s build! 🚀...
