解析 — tap a word
Japanese (language)
Parse
Every sentence breaks into its real parts — reading, meaning, JLPT level. Nothing is a black box.
Remember
FSRS schedules each word for the precise moment you're about to forget it — the modern successor to SM-2.
Immerse
Study from text you actually care about, not invented textbook lines. The words you meet are the words you keep.
The study loop
One card at a time,
scheduled to the day.
See a word. Recall it, or don’t. Rate how it felt — Again, Hard, Good, Easy — and the schedule reshapes itself around your honest answer. Furigana hides until you ask for it, so recall stays real.
おぼえる
to memorize; to learn
新しい言葉を覚えるI memorize new words.
