The m3e-canvas project has gained incredible traction for rapid vibe-coding UI interfaces. However, translating raw visual layout JSON into clean, structured system prompts for downstream LLM execution remains a common manual hurdle.
To solve this, I built a zero-dependency, browser-based utility: M3E Prompt Structured Exporter.
What it does
- Accepts raw M3E canvas component definitions or layout structures.
- Generates structured, production-ready system prompts for LLMs (Claude, GPT-4o, DeepSeek).
- Runs entirely client-side with zero data storage or external dependencies.
