Turn your Japanese notes into free online flashcards
Upload a PDF, slides, DOCX, text or a photo of a textbook page. DeckOwl builds Japanese flashcards from your material and schedules reviews with spaced repetition.
Why your own Japanese material beats a generic deck
Plenty of free online Japanese flashcards exist, but most are generic word lists that skip the kanji and grammar your class uses this week. Making cards from your own lecture slides or textbook pages keeps review tied to what you will actually be tested on.
- Kana charts from your textbook turned into cards you can review in the browser
- Vocabulary lists from class slides with the reading and meaning on the back
- Grammar points pulled from your notes, such as particles and verb forms
- Free plan includes 3 generations a month; Plus adds PDF, DOCX, Anki and CSV export
Built from your own material
Upload a PDF, slides, DOCX, notes or a photo of a page and get cards that match what your course covers.
Spaced repetition
Cards come back just before you would forget them, so kana, kanji and vocabulary stay put longer.
Study free in the browser
The free plan includes 3 generations a month and browser study, with no credit card needed to start.
How it works

Study in the browser
Practice a few minutes a day and let spaced repetition decide when each card returns.

Frequently asked questions
How should I start learning hiragana and katakana with flashcards?
Learn a small group of characters at a time, review them every day, and add new ones only after the earlier ones feel automatic. Spaced repetition handles the scheduling so you spend less time guessing what to review.
Is it better to memorize Japanese vocabulary with example sentences?
Yes, in most cases. A word learned inside a sentence shows its grammar and typical use, which makes it easier to recall and apply later.
Is DeckOwl really free to use?
The free plan includes 3 generations per month and studying in the browser. Exporting to PDF, DOCX, Anki or CSV is part of the paid Plus plan, which costs $99.90/year or $9.99/month.
Can I turn a photo of a Japanese textbook page into flashcards?
Yes. Photos of pages are read with text recognition, so you can upload one and generate flashcards from the text it contains.
