How to make flashcards from your own study material

Your lecture slides and textbook chapters already contain the questions you will be tested on, so the fastest way to make flashcards is to start from that material instead of writing every card by hand.

  • Upload the source you already study from, such as slides, a PDF chapter or class notes.
  • Check each card for one idea, a clear question on the front and a short answer on the back.
  • Study in short daily sessions so spaced repetition can space out the cards you know well.
  • Export to Anki or CSV when you want to keep studying elsewhere, which is available on the Plus plan.
Example biology flashcards for a cell structure unit
What is the function of the mitochondrion?It produces most of the cell's ATP through cellular respiration.
What is osmosis?The movement of water across a semipermeable membrane from lower solute concentration to higher solute concentration.
Where does protein synthesis take place?On ribosomes, which are free in the cytoplasm or attached to the rough endoplasmic reticulum.
What does the Golgi apparatus do?It modifies, sorts and packages proteins and lipids for transport or secretion.
How do prokaryotic and eukaryotic cells differ?Prokaryotes lack a membrane-bound nucleus, while eukaryotes have one.

Works from your material

Upload PDF, DOCX, PPTX, plain text or images. Photos of pages are read with text recognition.

Spaced repetition built in

Cards you find harder come back sooner, so study time goes to what you are most likely to forget.

Study in the browser

The free plan includes 3 generations per month and browser study. Paid plans add exports to PDF, DOCX, Anki and CSV.

How it works

Upload your material

Add a PDF, slides, a document, notes or a photo of a textbook page.

Generate the cards

DeckOwl drafts flashcards from the content. Review them and fix anything that is off before you start.

Study on a schedule

Work through the deck with spaced repetition and keep going back to the cards you miss.

Good cards ask one specific question and keep the answer to a sentence or two. Before you study, check that each front makes sense on its own and that each back gives the answer without extra context. DeckOwl drafts the cards, and you edit the ones that need work.

Once the deck exists, review it in short sessions rather than one long cram. Spaced repetition brings missed cards back sooner, which is where most of the practice time should go.

Frequently asked questions

How many flashcards should I make for a biology unit?

Aim for one card per key term or concept rather than one per sentence, so each card tests a single idea. A typical chapter can produce a few dozen cards that you review in short daily sessions.

How do I write flashcards that actually help me remember?

Write each front as a specific question and keep the back to one or two sentences. Cards you get wrong will come back more often, which is how spaced repetition targets the gaps.

Can I export my flashcards from DeckOwl?

Exports are a paid feature. The Plus plan includes PDF, DOCX, Anki and CSV export, while the free plan lets you study flashcards in the browser with 3 generations per month.

Can I make flashcards from a photo of a textbook page?

Yes. Photos of pages are read with text recognition, so you can upload them alongside PDFs, DOCX, PPTX and plain text notes.
