About

StemJSON is a declarative language based on JSON that lets AI generate native mobile app screens, logic, and entire features, which native runtimes (iOS and Android SDKs) then render on-device. It supports server-driven UI updates without app-store releases and a sandboxed "Stem AI Area" where end users describe changes in natural language and get a natively rendered result.

Why it made the leaderboard

StemJSON lets an LLM emit a compact JSON spec that renders as native iOS/Android UI on-device, enabling server-driven screens and end-user AI customization without app-store round-trips, backed by a public spec and native runtime SDKs.
