Train Your Brain — AI Education Kids Actually Use

Also ours. Train Your Brain (TYB) is a product we own and operate. It's where a lot of our AI-for-kids patterns were first proven before they showed up in client work.

What it does

TYB is an AI-powered learning app for children, built around four things parents and kids actually reach for:

• Conversational tutoring — a chat tutor that explains, quizzes, and adapts, with guardrails built for kids rather than bolted on.
• Story generation — creative-writing help that turns a kid's idea into a real story they can finish.
• Homework help by photo — snap a picture of the worksheet; the app reads the image and walks through it instead of just spitting out an answer.
• Family subscriptions — one account, multiple kids, billing that a parent can actually manage.

How it's built

A Rails 7.1 backend API does the heavy lifting — auth, subscriptions, the AI orchestration, content moderation — and a React Native / Expo app is what families touch. It's multi-tenant, so the same platform cleanly separates families, kids, and content.

The interesting engineering is in the safety and moderation layer. "AI for children" is a sentence that has to survive contact with a real parent, a real regulator, and a real eight-year-old trying to break it. That meant designing the content pipeline so that what reaches a child is filtered, age-appropriate, and logged — the same moderation discipline that later carried straight into PollyStop's content factory.

Why it's on this page

TYB is the oldest of our own consumer products, and the one that taught us the shape we now build for clients: a friendly app on the surface, a careful AI pipeline underneath. The tech stack here — Rails + React Native, multi-tenant, photo/image analysis, subscription billing — is the same toolkit we bring to a client build.
