Your First Capstone

Time to build something. Your Builder capstone asks you to design an AI assistant that helps your community. You’re not coding it yet — you’re designing it. That’s the hardest part anyway.

The four questions

1. Who is it for?Be specific. “My grandfather who’s learning to use email.” Not “old people.”
2. What does it help them do? One thing. Not ten.
3. What would a great first conversation look like? Write it out like a script.
4. What’s one way it could go wrong, and how would you prevent that?

Examples from past capstones

• A homework buddy that won’t give you the answer — only hints — for kids whose parents can’t help with math.
• A pet-care advisor that warns you when a home remedy is actually unsafe for dogs.
• A library chatbot that suggests the next book based on the mood you’re in, not just the last book you read.
• A weekly review assistant for a middle-school student with ADHD that gently prompts them through their planner.

What to submit

Upload a 1-page PDF or image. The Who / What / Script / Failure Mode sections. That’s it. Real, specific, humane. Your librarian (or parent) can review and award the Builder badge.

Why this is the capstone

Designing an AI is not the same as using an AI. This is the practice that matters most as you become a Creator. The code is the easy part. Knowing what’s worth building is the hard one.
