jpdb

jpdb is a Japanese dictionary and learning system that's designed to help you learn vocabulary and kanji. It's a good tool for people who want to learn Japanese through immersion, watching anime, reading visual novels, light novels and web novels.

jpdb can extract vocabulary from any text you supply, so you can learn words in the context of the media you enjoy. It also comes with thousands of prebuilt decks based on Japanese media. It uses a spaced repetition algorithm based on Heisig's Remembering the Kanji system, but with its own set of more nuanced keywords.

Here are some of the features of jpdb:

• State-of-the-art spaced repetition algorithm: The algorithm is based on modern machine learning techniques that handle lapses and irregular reviews better than older spaced repetition algorithms like the SM-2 algorithm.
• Automatic i+1 sentence cards: Vocabulary cards are automatically converted into sentence cards so you can learn words in context.
• Millions of example sentences: A large library of real Japanese sentences offers contextual learning opportunities.
• Personalized media suggestions: Recommendations are based on the words you've learned, so you can find your next show to watch.
• Global progress tracking: Your progress is tracked across all decks, so you can see your overall progress.
• Flexibility: You can learn in any order and at your own pace, without artificial limits on progress.

jpdb's algorithm is designed to handle situations where you need to catch up on a large number of due cards. It also offers flexibility in terms of review intervals, so you can set them based on your ideal retention rate and daily workload.

jpdb can import existing Anki databases, so you can bring your previous learning with you. It also uses dictionaries like JMdict/EDICT and KANJIDIC, and incorporates Wiktionary and Tatoeba content under Creative Commons licenses.

There is no mobile app yet, but you can add the website to your home screen for an app-like experience. jpdb is still a work in progress, with a planned feature to add manga to its database in the future.

jpdb is good for anyone who wants to improve their Japanese language skills, but especially for people who want to immerse themselves in Japanese media. It's a powerful and personalized learning system that can accommodate different needs and learning styles. Check out the website to learn more and get started.
