Station. Saved to your library with readings, meaning, and encounter history.
Core loop
Scan. Understand. Remember.
KanjiKamera sits between raw OCR and traditional study apps. It captures kanji, explains what you found, and turns repeated encounters into actual memory.
Scan
Use OCR to pull kanji from signs, menus, books, and everything else you encounter in the wild.
Understand
Open a kanji detail view with meaning, readings, example usage, and JLPT context in seconds.
Remember
Save what you discover into a personal logbook that tracks when you first saw it, how often it appears, and how familiar it feels.
Unified product
One account, one synced library, one premium experience.
KanjiKamera is a multi-client product, not a disconnected app and site. The website markets the product, serves as the web app entry point, and acts as the account and billing hub.
Use KanjiKamera in your browser or on Android with one account.
Sync saved kanji, history, progress, and subscription status across clients.
Keep discovery and learning together instead of splitting OCR and study across separate tools.
Grow into review systems, premium features, and deeper progress tracking over time.
Platform architecture
Browser app, Android app, shared backend.
The product story now reflects the actual architecture: Next.js on the web, Capacitor on Android, Supabase for auth and data, and Stripe for premium access with server-side validation.
Built to scale
- Auth, billing, and subscription state belong to the backend.
- Saved kanji and learning history stay synced across clients.
- Future review systems can build on the same shared data model.
