StemJSON lets a published mobile app grow new native features from plain words. Users get functions the app never planned for, and developers serve individual needs without building each one or shipping a release. A user describes what they need inside the app, AI writes a StemJSON module, and the runtime inside the app checks it and builds it from real iOS or Android parts, within limits the app’s developer set in advance

Could you build this?
Partial The product UI and AI module generation are buildable, but safely running AI-generated native code inside a shipped mobile app is a hard security and runtime problem.
What it would actually take: A real version needs a sandboxed interpreter or bytecode runtime embedded in iOS and Android apps, with capability-restricted access to device APIs. It also needs a permissions model and review process that stays within App Store rules. Those security and platform-engineering skills are the hard part, and vibe coding alone won't supply them.
