Partial The app and explanation UI are straightforward to build, but the 17,000+ explained questions are a large content asset that requires substantial curation and quality control.
What it would actually take: The app itself is a quiz engine with timed tests, spaced retry, and analytics. The hard piece is content: producing accurate, plain-English explanations for every JLPT question across N5 to N1 needs Japanese-language expertise and careful review, or licensed question data. LLM drafting helps but accuracy checks need fluent teachers.
