Sandbox

A privacy-first AI app builder built for K-12 STEM students.

Students describe what they want to build — a simulation, a calculator, a quiz — and get a working app they can change, break, and explain. Teachers own the classroom, the roster, and the guardrails.

Privacy first, not privacy retrofitted

Never used to train models
Student prompts, code, and writing are never used to train AI models.
No student PII by design
Students don't need an email address, an account, or a password. A student is a display name and a PIN inside one teacher's classroom.
No third-party trackers
No ad trackers and no third-party analytics anywhere students work.
Schools own their data
Export or permanently delete everything for a class on request.
Sandbox — built for classrooms.
