Quiz yourself on any PDF with Anki-style flashcards
Upload lecture slides, a reading PDF or a photo of handwritten notes. DeckOwl builds flashcards and quiz questions you can review with spaced repetition.
How a flashcard quiz works with your own notes
Most students already have the material for a good quiz: lecture slides, a reading PDF and a page of handwritten notes. The hard part is turning that into questions you can actually review. Anki-style flashcard quizzes solve this by pairing each question with a short answer and scheduling it for review at the right time.
- Flashcards and quizzes generated from the files you already have
- Spaced repetition scheduling on the free plan and above
- Multiple choice, true/false and short answer questions with explanations
- Export to Anki, CSV, PDF or DOCX on Plus
Built from your material
Start with the PDFs, slides, notes or photos you already have. Text in images is read with text recognition, so no retyping is needed.
Quizzes with explanations
Get multiple choice, true/false and short answer questions. Each one comes with an explanation so a wrong answer teaches you something.
Spaced repetition built in
Cards you find hard come back sooner, and easy ones spread out. Your review schedule adjusts as you study.

Generate flashcards and quizzes

Study in the browser
Review on a spaced repetition schedule. Export to Anki or CSV with a paid plan.
DeckOwl reads your files and drafts the cards, so you spend your time checking and studying rather than writing. Multiple choice, true/false and short answer quizzes each include an explanation, which helps when a question tests a concept you half remember.
Spaced repetition keeps the review load manageable. Cards you miss come back the same day or the next, while cards you know are pushed further out. Students who review in short sessions over several days tend to keep more than those who cram the night before.

Frequently asked questions
How many flashcards should I make for a vocabulary unit?
Start with 20 to 40 cards per unit so each review session stays short. Add more only after you can answer most of the existing cards without hesitating.
What makes a good flashcard quiz question?
A good question asks for one fact, has a single clear answer, and avoids cues that give the answer away. Short answers are better for recall than true/false because they require you to produce the word yourself.
Can I export my flashcards to Anki?
Yes, export to Anki is included in the Plus plan at $39/year or $7.99/month. The free plan lets you study in the browser but does not include exports.
Is there a free plan?
Yes, the free plan includes 3 generations per month and browser study, and you do not need a credit card to start. Students with a school email get 40% off paid plans.
