Show HN: StemJSON – a language for LLMs to extend native mobile apps on the fly
StemJSON, introduced on Hacker News, is a new language designed to let large language models modify native mobile applications in real time. By using a JSON‑style format, developers can describe UI components, logic, and platform‑specific calls that the LLM can generate and inject without recompiling the app. The approach aims to speed up feature iteration and reduce development overhead.
