Japanese Study Desk

All-in-one lesson materials, audio, and vocabulary for self-learners

Problem

Self-learners of Japanese using textbooks like Minna no Nihongo constantly switch between textbook, audio, and vocabulary lists, losing focus and efficiency. Existing tools are either too simple, require registration, or are paid.

Solution

A web tool where users select their current lesson and see textbook text, play accompanying audio, and click unfamiliar words to see kana and example sentences—all on one screen. Supports Minna no Nihongo and Shin Nihongo no Kiso, no registration required.

Users

Japanese self-learners, especially beginners using Minna no Nihongo or Shin Nihongo no Kiso

MVP

Lesson-based text display; embedded audio player; click-to-see kana and examples; support for two major textbooks; no registration

Revenue

Free basic + premium one-time $10 for offline download, quizzes, progress tracking

Why now

Language self-learning is growing, but existing tools are fragmented and poor. Indie developers can quickly build an aggregated learning page without complex backend.
