Make your own Japanese vocab deck from your study notes
Upload a PDF, slides, notes or a photo of a page. DeckOwl builds flashcards with spaced repetition, so you study the words your course actually uses.
Why a custom Kaishi-style deck beats a premade list
A premade list teaches the same words to everyone, but your class, textbook and reading assignments use their own vocabulary. Building a Kaishi-style Anki deck from your own material keeps the cards tied to what you will actually be tested on.
- Start with the words in your current chapter so each session matches your class.
- Add a short example sentence to the back of each card to learn grammar in context.
- Review new cards daily and keep the daily count low enough that reviews never pile up.
- Export to Anki on Plus if you want to keep one deck across devices.
Works from your own material
Upload PDFs, DOCX, PPTX, plain text or photos of pages. Text recognition reads the images, so handwritten-free printed notes work well.
Spaced repetition built in
Cards come back at the right time, so words you miss appear more often and words you know fade into longer intervals.
Export to Anki on Plus
Plus includes Anki, PDF, DOCX and CSV export, so your deck can move into the Anki app you already use.
How it works
Upload your vocab source
Add a PDF, slide deck, notes file or photo of a vocabulary list in Japanese.
Generate flashcards
DeckOwl creates front and back cards from your material. Review them and remove any you do not need.
Study or export
Study in the browser on the free plan, or export to Anki with a Plus plan.
Kaishi is a frequency-ordered Japanese vocabulary list, and it is a useful reference for choosing what to learn first. If you want the same kind of ordering, sort your source material by how often words appear in your lessons and generate cards from those sections first.
Spaced repetition does the scheduling, so you only review what you are close to forgetting. Export to Anki when you want a desktop or phone deck with your own history and add-ons.

Frequently asked questions
How many new words should I add per day to a Japanese vocabulary deck?
Many learners start with 10 to 20 new cards a day. Adjust the number based on how much review time you can keep up with each day.
Should I study Japanese words in sentences or as isolated vocabulary?
Learning words in short sentences helps with context, particles and grammar, while single words are quicker to drill. Try a mix, and put one example sentence on the back of each card.
Can I export my cards to Anki?
Yes, Anki export is a Plus feature at $99.90/year or $9.99/month. The free plan lets you study in the browser but does not include exports.
Do I need a credit card to start?
No. You can start on the free plan with 3 generations per month and no credit card.
