Turns the dozens of times learners check their phones each day into passive kanji exposure, then reinforces recall with personalized reviews. It fits into existing habits instead of demanding another long study session.
Japanese learners often recognize kanji during study but forget them between sessions. Traditional flashcards require deliberate app opens and make it difficult to sustain frequent, contextual exposure.

PDF Vault
PDF Vault is a done-for-you digital business-in-a-box. Members license ready-to-sell PDFs that come with a hosted sales page, and they keep 100% of their sales. It earns money two ways: one-time license fees plus recurring monthly hosting. Tiered pricing raises the price as licenses sell, so each product earns more as it fills and early buyers move fast. Licenses are capped, and new products launch in weekly drops, so the doors open just once a week. That scarcity creates real urgency.
