Turn your language notes into Duolingo-style flashcards with AI
Upload a vocabulary list, a textbook chapter, class slides or a photo of your notes. DeckOwl turns them into flashcards you can review on your own schedule.
Why turn your language practice into flashcards
Many learners who practice a language on Duolingo want the same vocabulary as Duolingo flashcards they can review on their own schedule. DeckOwl builds that kind of deck from material you already have, such as a vocabulary list, a chapter PDF, slides from class or a photo of your notes. The AI pulls out each term and its meaning, so the deck matches what you are actually learning.
- Turn a vocabulary list or textbook chapter into a deck in one upload.
- Keep the target word on the front and the meaning on the back for quick recall.
- Review missed words more often without rebuilding your cards by hand.
- Export to Anki or CSV on the Plus plan when you want to study outside the browser.
Built from your material
Upload PDF, DOCX, PPTX, plain text or photos of pages. The AI reads the text and pulls out the terms and meanings.
Spaced repetition
Cards you miss come back sooner, and cards you know are spaced further apart, so review time goes to the words that need it.
Study anywhere
Review in the browser for free. On Plus you can export to Anki or CSV and keep your deck wherever you study.
How it works
Add your vocabulary
Paste a word list, upload a unit PDF or snap a photo of your notebook page.
Generate the deck
DeckOwl creates flashcards with the term on the front and the meaning on the back.
Review on a schedule
Study in short sessions. Spaced repetition brings back the cards you are most likely to forget.
Flashcards work best when you review them in short sessions over several days. Spaced repetition handles the timing, so you spend less time on words you already know. The free plan includes 3 generations per month and browser study, and the Plus plan adds unlimited generations with PDF, DOCX, Anki and CSV export.

Frequently asked questions
How many flashcards should I make for one vocabulary unit?
Start with the words from a single lesson or chapter, which is often a few dozen terms. Smaller sets are easier to review every day, and you can add more later.
What is the best way to study language vocabulary with flashcards?
Say each word aloud before you flip the card, then check the meaning and note the ones you missed. Reviewing over several days works better than one long session.
Can I export my flashcards to Anki?
Yes, export to Anki is available on the Plus plan, along with PDF, DOCX and CSV export. The free plan lets you study in the browser without exports.
Is there a free plan, and do I need a credit card?
Yes, the free plan includes 3 generations per month and browser study. No credit card is needed to start, and students get 40% off with a school email.
