A staged 14-section build prompt for a cinematic launch page in Greta: scroll-triggered reveals, a live countdown, a waitlist form saving to a Supabase database you own, confirmation emails, and an optional referral loop.

What's inside
  • A staged 14-section prompt for a cinematic launch page
  • Scroll-triggered story reveals and a live countdown timer
  • A waitlist form wired to a Supabase database you own
  • Real confirmation emails, a live signup counter, and a referral loop
  • GitHub-synced and deployed to your own domain

Your MVP Is a Launch Page

The exact staged prompt to build a cinematic product launch page with Greta — scroll-triggered reveals, a live countdown, and a waitlist form wired to a real database with real emails. Fed in 14 sections, one at a time. Real backend, real signups, zero code from you.


Why 14 Sections, Not One Giant Prompt

One enormous prompt gets skimmed and half your requirements get dropped. Breaking the build into focused, sequential steps produces a far more detailed, consistent result: each step gets the model's full attention, each finished section becomes locked context for the next, and you course-correct live before anything is baked in.


What You Walk Away With

A cinematic launch page that actually captures signups — scroll-triggered story, live countdown, and a waitlist form saving to a Supabase database you own, with real confirmation emails, a live signup counter, an optional referral loop, GitHub sync, and deployed to your own domain.

The full 14-section build prompt is in the PDF.
