🍪 Custom LEGO
"Turn any photo into a buildable LEGO kit — powered by AI, delivered to your door."
The Idea
BrickStack is an AI-powered web app where users upload a photo or describe an object in plain English, and the platform generates a buildable LEGO brick model complete with a parts list (using real BrickLink part IDs) and step-by-step instructions. Users can tweak designs, order physical kits for delivery, and browse/remix community creations in a public feed. Revenue comes from tiered kit pricing based on brick count and complexity.
Who It's For
LEGO enthusiasts (18–45), gift buyers looking for unique personalized presents, parents wanting custom builds for kids, and the broader "personalized product" market (overlaps with custom phone cases, custom puzzles, etc.).
What's Built
The prototype will focus on the design generation loop and community feed — the two hardest-to-validate pieces. Physical fulfillment will be simulated (order confirmation page, no real shipping integration).
In scope:
- User authentication (sign-up, login, logout)
- Design creation: text prompt OR image upload → AI generates a LEGO-style render + parts list
- Design detail page with 3D-style render, parts list, estimated price tier, and step-by-step instruction preview
- Save designs to user profile
- Public community feed of published designs
- Remix/fork: clone someone else's design, modify the prompt, regenerate
- Simulated checkout flow (select tier → order confirmation, no payment processing)
Out of scope for MVP:
- Real payment processing (Stripe integration deferred)
- Physical fulfillment / shipping logistics
- Real-time 3D editor for brick-by-brick editing
- Revenue share / creator payouts
- Mobile native apps
