Lyric-to-Flashcard Japanese Learner

Turn favorite Japanese songs into readings, grammar notes, and reviewable mnemonic cards

Problem

Native Chinese speakers learning Japanese can guess meanings from kanji but struggle with readings and kana, and generic mnemonics don't stick. Existing apps either drill isolated vocabulary or break down lyrics without connecting to spaced repetition, so learners forget soon after.

Solution

Users paste Japanese lyrics or short texts; the tool breaks down per-word readings, grammar structure, and expression logic, then generates editable mnemonic cards and adds them to a spaced-repetition deck. Supports custom mnemonics and song/text-based decks.
