My twins (in high school) and I are building an AI study buddy.The idea is simple. A peer-level “study friend” you can work alongside, ask questions, and stay on track with.

It’s not doing anything ChatGPT or Claude couldn’t do. The goal is packaging it into something that feels a high-schooler would actually want to use when they’re studying.

We are also using this as a weekly project to learn the abstract stuff. Product thinking, design, pricing, marketing, and how to turn a vague idea into something real. Each week the kids prioritize a feature, research it, write up the idea, and then we build (or cut) it together.

Our stack is Claude Code, TypeScript, React and it's hosted on Cloudflare Pages for frontend + Workers for API.
