A simple loop that
builds real retention.

Choose individual kana characters, JLPT vocabulary by level, grammar points, or a reading passage — or use a pre-built preset.

New to a character or grammar pattern? Enter Unified Learning Mode for guided introduction cards before being tested.

Cards are presented one at a time. Type or speak your answer. Instant feedback on every response.

After each session, SM-2 schedules your next review. Hard items come back soon; mastered items less often.

Session summaries and a statistics dashboard show accuracy, streaks, and where you need more work.
