Skip the generic word list. Upload your own JLPT N4 handouts, slides or photos and get flashcards that match the words in your course.
Why build N4 vocabulary cards from your own material
Most ready-made N4 vocabulary flashcards PDF files cover a generic word list, but your textbook and class handouts use the exact words you will be tested on. Cards made from that material keep your review focused on what your course actually covers.
- Use the exact vocabulary from your own lessons, not a generic list
- Review words in short sessions, with spaced repetition scheduling the repeats
- Keep the reading, meaning and an example sentence on the same card
- Add new lessons as they arrive and build the deck over the term
Your own material
Upload a PDF, DOCX, PPTX, notes or a photo of a page and get flashcards built from the words in your class handouts.
Spaced repetition
Cards you miss come back sooner, so your study time goes to the words you are still forgetting.
Study anywhere
The free plan lets you study in the browser. Plus adds PDF, DOCX, Anki and CSV export for printing or your own decks.
How it works
Upload your list
Add a PDF, slides, notes or a photo of your vocabulary sheet.
Review the cards
Check the generated fronts and backs and correct any word the reader misread.
Study on schedule
Work through the deck regularly and let spaced repetition bring back the words you miss.
DeckOwl reads PDFs, slides, DOCX files, notes and photos of pages, then creates flashcards you can review with spaced repetition. Because you choose the source, you can add each new lesson as it arrives instead of searching for another printable sheet.
Pair every word with its reading and a short example sentence when you study. Vocabulary sticks better in context than as an isolated translation.

Frequently asked questions
How should I study N4 vocabulary so the words stick?
Review a small number of new words each day and revisit them on a schedule rather than cramming a long list once. Practicing words in example sentences helps you recall their meaning and how they are used.
Should I learn kanji readings along with the vocabulary meanings?
Yes, learning the reading and the meaning together is more useful for the JLPT than memorizing meanings alone. Many learners also add one example sentence per word to make recall easier.
Can I export my N4 flashcards as a PDF?
PDF export is a paid feature included with Plus, which costs $39/year or $7.99/month. The free plan lets you study the flashcards in your browser without exports.
Do I need a credit card to start?
No, you can start without a credit card. Students also get 40% off with a school email.
