Turn Japanese notes and textbook photos into flashcards
Upload a PDF, slide deck, page photo or plain notes and get flashcards for kana, kanji and vocabulary, scheduled with spaced repetition.
How to study Japanese flashcards on iOS
Japanese flashcards work best when they come from the lesson you are actually studying, such as the vocabulary list from chapter 4 or the kanji your teacher handed out. Upload that material and the cards match your course instead of a generic list.
- Upload a photo of a textbook page and get cards for the vocabulary on it.
- Keep kana, kanji and vocabulary in separate decks so each one can be reviewed on its own schedule.
- Edit any card before studying to fix a reading or correct a translation.
- Use spaced repetition so new material comes back before you forget it.
Works from your own material
Upload a PDF, DOCX, PPTX, text file or photo of a page. Your Japanese lesson becomes flashcards without retyping.
Spaced repetition built in
Cards come back at the intervals that suit how you forget, so you review the kanji you are about to lose and skip the ones you know.
Export when you need it
Plus adds Anki and CSV export, so your Japanese deck can move to another app or device you already use.
How it works
Upload your lesson
Add a PDF, slides, notes or a photo of your textbook page. Image text is read with text recognition.
Generate your cards
DeckOwl builds flashcards from the material. Check the fronts and backs and remove anything you do not need.
Review on a schedule
Study the deck in your browser. Spaced repetition brings back the cards you are most likely to miss.
DeckOwl runs in the browser, so the free plan lets you study on your phone without a download. Exporting to Anki or CSV is part of the paid Plus plan, so check that before you build a large deck you want to keep elsewhere.
Kana and kanji need different handling. Put hiragana or katakana on one side and the sound on the other, and give kanji a meaning plus a reading on the back so you practice both.

Frequently asked questions
What should I learn first when studying Japanese with flashcards?
Most learners start with hiragana and katakana, then move to common vocabulary and kanji. Learning the kana first makes reading the rest of your material much easier.
How many kanji should I put in one deck?
Keep each deck to the kanji from a single lesson or unit so you can finish reviewing it. Add more kanji once you can recall the current set reliably.
Can DeckOwl make Japanese flashcards from a photo of my textbook?
Yes. Photos of pages are read with text recognition, and you can generate flashcards from the recognized text. Check the result for characters the recognition missed.
Is DeckOwl free, and what does Plus add?
The free plan includes 3 generations per month and browser study, but no exports. Plus is $39/year or $7.99/month and adds unlimited generations along with PDF, DOCX, Anki and CSV export.
