How to Make Flashcards from a PDF

Step 1

Step 2

AI extracts key concepts

The AI identifies the most important terms, definitions, concepts, and relationships in your document. Each flashcard has a clear question on the front and a concise answer on the back, designed for effective recall practice.

Step 3

Estudia con repetición espaciada

Review your flashcards using Quizgecko's built-in spaced repetition system (based on the SM2 algorithm). Cards you struggle with appear more frequently, while cards you know well are spaced out — so you focus your time where it matters most.

Why Convert PDFs to Flashcards?

Flashcards remain one of the most proven study techniques in cognitive science. The combination of active recall (retrieving information from memory) and spaced repetition (reviewing at optimal intervals) has been shown to dramatically improve long-term retention compared to passive reading.

The problem? Making flashcards by hand is tedious. A single textbook chapter can take an hour or more to convert into a good flashcard set. Quizgecko does it in seconds.

Spaced Repetition Built In

Quizgecko's flashcard system uses an algorithm based on SM2 — the same approach used by Anki and other dedicated flashcard apps. As you review cards, the system tracks which ones you find easy and which ones you struggle with, then schedules reviews at the ideal time to maximize retention.

You don't need to manage review schedules manually. Just open your deck and study the cards that are due.

More Than Just Flashcards

When you upload a PDF, Quizgecko can also generate:

  • Quizzes with six question types for deeper testing
  • Study notes that summarize your document into structured key points
  • AI podcasts that turn your content into an audio study session

All of these are generated from the same upload, so you get a complete study toolkit from a single PDF.

Export and Compatibility

Need your flashcards in another tool? Quizgecko supports exporting to Anki-compatible formats, so you can use your cards wherever you prefer to study. Cards also sync across devices — create on your laptop, review on your phone.

Frequently asked questions

If you have any questions or feedback, please visit our help center.

The AI identifies key terms, definitions, important facts, and conceptual relationships in your PDF. It creates question-answer pairs that target the most important information for recall practice. You can edit, delete, or add cards after generation.

Yes. Quizgecko supports exporting your flashcard decks in Anki-compatible formats, so you can import them into Anki or other flashcard apps if you prefer.

Spaced repetition is a study technique where you review material at increasing intervals. Cards you get wrong are shown again sooner, while cards you know well are spaced further apart. Quizgecko uses the SM2 algorithm to schedule reviews automatically.

The number of flashcards depends on the content density of your PDF. A typical textbook chapter might produce 30-60 flashcards. You can always generate more or trim the set to focus on specific topics.
