Study Japanese vocab with flashcards made from your own material
Upload your Japanese class notes, slides or photos of textbook pages. DeckOwl builds flashcards you can review with spaced repetition, so kana, kanji and vocabulary stick.
Why build Japanese flashcards from your own material
Most Japanese courses hand you vocabulary in lesson order, but your memory works best with the words you actually meet. Japanese flashcards made from your own notes and textbook pages keep your review tied to what you are studying this week.
- Upload Japanese vocab lists, lesson slides or textbook photos and get cards from that exact content.
- Keep hiragana, katakana and kanji in separate decks, or mix them, depending on where you are in the course.
- Review cards in the browser on the free plan, or export to Anki, CSV or PDF on Plus.
- Regenerate a deck after each chapter so new vocabulary is added without rebuilding the whole set.
Built from your own lessons
Upload PDFs, DOCX or PPTX files, plain notes, or photos of pages. Text recognition reads the Japanese in your images.
Spaced repetition
Cards come back at the intervals where you are most likely to forget them, so you spend less time on words you already know.
Export when you need it
Plus users can export to Anki, CSV, or PDF for printing or for studying on another device.
How it works
Add your material
Upload a vocab list, a lesson PDF, a slide deck or a photo of a page from your textbook.
Generate flashcards
DeckOwl creates flashcards from the Japanese terms, readings and meanings in your material.
Review on a schedule
Study in the browser each day. Cards you miss return sooner, and cards you know come back later.
Paste a vocab list or upload a photo of a chapter and DeckOwl turns the terms, readings and English meanings into cards. Kanji with their readings and example words can sit on the same card so you practice recognition and recall.
Spaced repetition does the scheduling, so you are not sorting the deck by hand. Start with a few pages, check that the cards match your course, and add more as the term goes on.

Frequently asked questions
Should I learn hiragana and katakana before kanji?
Most courses teach hiragana first, then katakana, then kanji, because kana are needed to read every kanji reading. Many learners overlap them after a few weeks, but kana cards should be solid before you work heavily on kanji compounds.
How many Japanese flashcards should I study each day?
Many learners start with 10 to 20 new cards a day and review existing cards alongside them. Keep the daily new count low enough that your reviews do not pile up.
Can I export my Japanese flashcards to Anki?
Yes, Plus includes export to Anki, plus PDF and CSV. Exports are a paid feature, so the free plan covers studying in the browser only.
Is there a free plan to try it first?
Yes. The free plan includes 3 generations per month and browser study, and you do not need a credit card to start.
