Turn any codebase into a deeply interactive, single-page HTML learning experience for vibe coders — people who build with AI but want to understand what they built. Trigger whenever someone says "explain this codebase," "help me understand this project," "make a course from this repo," "teach me how this code works," "I want to understand the architecture," "turn this into something I can learn from," or shares a GitHub link and wants to understand it. Also trigger when someone says they feel lost in their own project, wants to debug more effectively, or wants to steer AI coding tools better. Rikai (理解, Japanese for "understanding") produces a single HTML file — no setup, no dependencies beyond Google Fonts — that teaches the codebase through storytelling, animated flows, interactive quizzes, and side-by-side code/English panels.
