Why your own flashcards beat premade decks for testing

Premade decks cover someone else's syllabus, so when you want flashcards to test what your professor actually taught, the notes and slides you already have are the better starting point.

Cards are drawn from your own course material, not a generic list.
Spaced repetition shows missed cards again sooner.
Photos of printed pages are read with text recognition.
Quizzes with explanations help you check understanding, not just recall.

Built from your material

Flashcards come from the PDFs, slides, notes or photos you already study, so the questions match what your course actually covers.

Spaced repetition

Cards you miss come back sooner and cards you know are spaced further apart, so review time goes to the material that needs it.

Quizzes and mind maps too

The same upload can produce multiple choice, true/false and short answer questions with explanations, plus mind maps of the topic.

Frequently asked questions

How many flashcards should I make for World War I causes?

Start with about 20 to 30 cards covering the main causes, key dates and alliances, then add more as you find gaps. Shorter sets are easier to review daily, which helps spaced repetition work.

What should my WWI flashcards focus on?

Focus on the causes most often tested, such as militarism, alliances, imperialism and nationalism, along with the 1914 trigger events. Write each card as a single question so you can check one idea at a time.

Can I export my flashcards to Anki?

Yes, exporting to Anki, along with PDF, DOCX and CSV, 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 to try this?

Yes, the free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start. Students with a school email get 40% off paid plans.
