Stop Forgetting Kanji. Write Them.

Kibikaku is a web-based Japanese kanji practice app. We combine active handwriting, Active Recall, and a Spaced Repetition System (SRS) to help you build lasting memory for JLPT exams, textbook studies, and everyday Japanese.

Standard SRS tools like Anki are general-purpose platforms, which are great for passive reading but can create an illusion of fluency. Kibikaku, however, is a specialized tool purpose-built exclusively for Japanese kanji study and memorization. We force you to build genuine muscle memory through active handwriting on your screen. Instead of just clicking a button, you physically write the character and self-assess, locking the kanji into your long-term memory.

It’s an algorithm-driven study method. Instead of cramming, the system schedules reviews at increasing intervals. You’ll see difficult kanji more often and easy ones less frequently. It’s like having a personal tutor who knows exactly what you’re about to forget.

Kibikaku is a reinforcement tool. It works best if you’ve already encountered the kanji in your studies. Our goal is to use handwriting as a memory trigger, helping you move characters from short-term to permanent memory.

We provide a quick-start demo deck so you can test the app immediately, but Kibikaku is designed for total customization. You can delete the demo at any time and build your own custom decks from scratch. Whether you’re adding a single kanji or words up to 12 characters, you control the study material.

Absolutely. You can add vocabulary manually one by one, or speed up the process using our bulk upload feature. We provide a downloadable .xlsx template right inside the app. Just fill it out and upload it to instantly generate custom flashcards for any textbook, course, or personal study goal.

No, and that’s by design! Kibikaku focuses on Active Recall. Instead of relying on an algorithm to correct you, you write the kanji and self-assess. This deliberate comparison is scientifically proven to build stronger visual and muscle memory than automated correction.

We’ve made it easy! Every card includes a direct link to Jisho.org, the world’s most trusted Japanese dictionary. You can verify stroke orders, radicals, and example sentences to ensure your practice is always accurate.

Yes! While our app works on any device, we recommend using a screen large enough for comfortable handwriting. Whether using a stylus or your finger, a larger surface ensures the best experience for your practice sessions.

Kibikaku is a web app, but you can install it on your phone! For Android, use Chrome's "Install app" option. On iOS, use Safari's "Add to Home Screen." This creates a shortcut that works just like a native application, anytime.

Yes! We hate subscription fatigue as much as you do. Alongside our monthly and annual options, we offer a Kibikaku Pro Lifetime plan. A single one-time payment gives you unlimited decks, infinite cards, and advanced statistics forever, no recurring fees.
