Rebuild a deck from the material you still have

Clearing out old decks is fine, but accidentally deleting Quizlet flashcards you still need is a real setback. DeckOwl cannot restore cards from another app, yet the notes, slides or PDFs you studied from are probably still on your computer.

  • Upload a PDF, DOCX, PPTX, text file or photo of a page
  • Get flashcards with spaced repetition scheduling
  • Start free with 3 generations per month and no credit card
  • Export to Anki or CSV with the Plus plan
Example intro biology flashcards on cell structure
What organelle produces most of a cell's ATP?The mitochondrion, through cellular respiration.
What is the function of the ribosome?It synthesizes proteins by translating mRNA into a polypeptide chain.
What does the Golgi apparatus do?It modifies, sorts and packages proteins and lipids for transport.
How do prokaryotic and eukaryotic cells differ?Eukaryotes have a membrane-bound nucleus and organelles, while prokaryotes lack both.

Works from your own material

Upload PDF, DOCX, PPTX, plain text or a photo of a page and the AI pulls out the key terms for your cards.

Spaced repetition built in

Cards are scheduled so you review the ones you are about to forget, instead of rereading the whole deck.

Quizzes and mind maps too

Turn the same source into multiple choice, true/false and short answer questions with explanations, or a mind map.

How it works

Upload your source

Add the file or photo you already have. Nothing needs to come from another app.

Generate and check

Review the AI flashcards, edit anything that looks off, and keep the ones you want.

Study on a schedule

Study in the browser on the free plan, or export to Anki, CSV, PDF or DOCX with Plus.

Upload those files and the AI flashcard generator builds a new set with spaced repetition, so you review the cards on a schedule rather than all at once. Good cards come from clear source material, so check the output and fix any term that was misread before you start studying.

The free plan includes 3 generations per month and browser study with no exports. Plus costs $39/year or $7.99/month and adds unlimited generations with PDF, DOCX, Anki and CSV export. Students get 40% off with a school email, and no credit card is needed to start.

Frequently asked questions

How do I keep track of which flashcards I still need to review?

Spaced repetition schedules each card based on how well you recalled it, so cards you find hard come back sooner. Study a little most days rather than cramming a full deck the night before a test.

How many flashcards should I make for intro biology cell structure?

Start with one card per organelle or term, then add cards for functions and for differences between cell types. Most students find a focused set of 30 to 60 cards from a single chapter easier to review than one huge deck.

Can I export my new flashcards to Anki?

Yes, export to Anki is included in the Plus plan, which costs $39/year or $7.99/month. The free plan lets you study flashcards in the browser but does not include exports.

Is there a free plan to try this first?

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