Questions & Answers

As answered by people managing Kanjidon and api-usage.

What makes your product unique?

Kanjidon's answer

Picture turning kanji study into an epic adventure, where each symbol is a card to collect and every Quiz a challenge to conquer. Kanjidon is an app that mixes gamification with learning, using a spaced repetition system (SRS) to lock kanji into your long-term memory.

Open packs, tackle dynamic Quizzes, follow lessons, and track your progress with detailed stats. Whether youโ€™re a beginner or a Japanese pro, Kanjidon makes every step fun and rewarding.

Why should a person choose your product over its competitors?

Kanjidon's answer

Kanjidon turns kanji into collectible cards with unique designs, like a trading card game. Each kanji has a rarity, and collecting them levels you up, all the way to 50!

Missions, rewards, and a global leaderboard add a competitive edge, while the SRS ensures youโ€™re learning for real, stress-free. Itโ€™s studying that feels like a game!

How would you describe the primary audience of your product?

Kanjidon's answer

Kanjidon is your all-in-one buddy for learning Japanese. Besides kanji cards, youโ€™ll find hiragana and katakana cards (for total beginners), plus vocab and grammar cards to master Japanese from every angle.

What's the story behind your product?

Kanjidon's answer

The cards are the core of Kanjidon: JLPT-themed packs (Kana, N5, N4, N3, N2, and even N1) each have 4 Kanjidon cards (6 for Premium users!). You need 30 Tama, the Kanjidon worldโ€™s coins, to open a pack. Open as many cards as you can and check out what they offer: each card has a meaning, an on reading, a kun reading, and an example sentenceโ€ฆ everything you need to learn kanji the best way!

Which are the primary technologies used for building your product?

Kanjidon's answer

Each Quiz section has 10 questions, but every time you get one wrong, that kanji goes back in the queue and pops up again during the Quiz section. Kanjidon's powerful SRS algorithm tailors your Quiz sections based on your Collection, mistakes, and successes, making every session super effective.

A Quiz isn't a testโ€”it's a challenge to grow and improve your skills.
