Questions
Will my progress be saved?
Yes — your deck and review history are saved in your browser's localStorage. Progress persists across visits as long as you don't clear your browser data. There is no account or server — everything stays on your device. Note: progress is device-specific; if you use a different browser or device, your streak and card intervals won't carry over.
What vocabulary is in the built-in deck?
The deck contains 11,840 JLPT-tagged Japanese words: nouns, verbs, adjectives, and adverbs that appear in Japanese news, fiction, and everyday speech. It covers N5 through N1, plus CA (Current Affairs — high-frequency vocabulary common in real Japanese but not on the official JLPT curriculum). These words only appear in Japanese-language content, so they cannot be learned from English-language study materials alone.
How does the scheduling work?
After you flip a card, you rate how well you remembered it: Again, Hard, Good, or Easy. The app uses that rating to decide when to show the card again. Rate a word "Easy" and it might not come back for two weeks. Rate it "Again" and it reappears tomorrow. This is the same method used by Anki — it's designed so you spend the least possible time reviewing words you already know.
How do I import words from Immerse Japanese?
Immerse Japanese PRO (paid tier) lets you export your encountered vocabulary as an Anki-format file. Open the extension, go to Settings → Anki Export. Then use the Import section on this page to load that .txt file. Your words will be added to your flashcard deck alongside the built-in vocabulary.
