## What is Sullivan Japanese?

Sullivan Japanese is a learning app for everyone studying Japanese.

Read, write, listen and speak — learn Japanese you can actually use, adapted to your level.

■ Graded by AI, instantly
Get specific, sentence-by-sentence feedback on your writing and speaking in seconds.

■ Always the right question
AI reads your ability across four skills and serves only the problem you should solve now — never too easy, never too hard.

■ Practice by talking with AI
An AI partner that weaves your own mistakes into a natural conversation, so you actually speak.

■ A habit that sticks
A daily plan and quests show what to do today, while streaks, XP, weekly leagues and achievements make studying a game you look forward to.

■ Built so you never get lost
Furigana readings and an interface in English, Chinese or Vietnamese keep beginners moving.

Learn every day for free. Premium unlocks unlimited practice, AI grading and AI tutor. Start with 7 days free.

Premium is an auto-renewable subscription (Monthly ¥980 / Yearly ¥5,800, with a 7-day free trial). Payment is charged to your Apple ID and auto-renews unless turned off at least 24 hours before the end of the period. Manage or cancel anytime in Settings > Apple ID > Subscriptions.
