A kanji flashcard app that turns your own notes into review cards
Upload a kanji list, a textbook chapter, slides or a photo of your notes. DeckOwl reads the material and produces flashcards you review with spaced repetition.
How a kanji flashcard app fits into daily study
Kanji are hard to memorize because one character can carry a meaning, an on-reading and a kun-reading, and many of them look alike. A kanji flashcard app helps by turning the lists and pages you already have into cards you can review in short sessions, so you are not copying characters by hand.
- Works with PDFs, DOCX files, PPTX slides, plain notes and photos of pages
- Cards are scheduled with spaced repetition so hard characters return more often
- Free plan includes 3 generations per month and in-browser study
- Plus adds unlimited generations and PDF, DOCX, Anki and CSV export
Cards from your material
Upload PDFs, DOCX files, PPTX slides, plain notes or photos of pages. Text recognition reads the kanji and their meanings so you do not retype lists.
Spaced repetition scheduling
Cards you miss come back sooner and cards you know drop out of rotation. The schedule adjusts as you study, so review time goes to the characters that need it.
Study in the browser
The free plan lets you study your kanji deck right in the browser. Plus adds PDF, DOCX, Anki and CSV export when you want to study elsewhere.
How it works
Upload your kanji material
Add a PDF of your textbook, a slide deck, typed notes or a photo of a vocabulary page.
Review the generated cards
Check the kanji, readings and meanings that were pulled from your material and fix any misreads before you start.
Study on a spaced schedule
Work through the day's cards, rate how well you recalled each one and let the schedule bring back the hard characters.
Spaced repetition is what makes the practice last. Each card is shown again at a growing interval, and cards you forget come back sooner. Over time that keeps the characters you know fresh while you spend more time on the ones that slip.
DeckOwl is an AI flashcard generator, so the deck is built from your own course material rather than a fixed word list. Upload the chapter your class is covering this week and you get cards that match what you are being tested on.

Frequently asked questions
How many new kanji should I add each day?
Many learners start with a small batch of new kanji each day, since reviews of older cards add up quickly. Spaced repetition handles the timing, so you can add more new cards on days when your reviews are light.
Should I learn kanji meanings or readings first?
Meanings first makes it easier to connect each character to a word, and readings are easier to absorb once you see them in context. Cards that pair a kanji with one common word help the readings stick.
Can I export my kanji flashcards to Anki?
Yes, export to Anki is included in Plus, along with PDF, DOCX and CSV export. The free plan lets you study flashcards in the browser without exports.
Can I make kanji cards from a photo of my textbook?
Yes, photos of pages are read with text recognition, and PDFs, slides and notes work too. Check the recognized text before studying, since small print or handwriting can be misread.
