Why a custom set beats copying a ready-made deck

Typing cards one by one from a 40-slide lecture deck is where most study sets stall. A Quizlet-style flashcards set built from your own notes matches the exact wording your instructor used, so you are drilling the material you will actually be tested on.

  • Works from PDFs, slides, DOCX files, plain notes and photos of pages
  • Cards are scheduled with spaced repetition so review time goes where it is needed
  • Each card set can also become quizzes with explanations or a mind map
  • Free plan includes 3 generations per month and browser study
Example plate tectonics flashcards
What is a divergent plate boundary?A boundary where two plates move apart, allowing magma to rise and form new crust, as at mid-ocean ridges.
What is subduction?The process where a denser oceanic plate sinks beneath another plate and into the mantle.
What evidence did Alfred Wegener use for continental drift?Matching coastlines, matching fossils such as Mesosaurus, and matching rock formations on continents now separated by oceans.
Where do most transform boundary earthquakes occur?Where plates slide horizontally past each other, such as the San Andreas Fault, where friction locks and then releases stress.
What supercontinent began breaking apart about 200 million years ago?Pangaea, which split into the continents that gradually drifted to their present positions.

Reads your real material

Upload PDF, DOCX, PPTX, plain text or photos of pages. Text recognition pulls the content so the cards come from your course, not a generic list.

Spaced repetition built in

Cards resurface at growing intervals based on how well you recall them, so you spend time on the ones you keep missing.

Quizzes and mind maps too

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

How it works

Upload your material

Drop in a PDF, slides, notes or a photo of a textbook page. No credit card is needed to start.

Review the generated cards

Check the flashcards DeckOwl creates, edit anything that looks off, and remove cards you do not need.

Study with spaced repetition

Study in the browser on the free plan. Paid plans add exports to PDF, DOCX, Anki and CSV.

The process is simple: upload the source, check the cards, and start reviewing. Because the cards come from your files, you can regenerate a set after a new lecture or add a second chapter without starting over.

Frequently asked questions

How many flashcards should I make for a plate tectonics unit?

A good starting point is one card per key term, boundary type or evidence item, which usually lands between 30 and 60 cards for a full unit. Trim any card that tests trivia instead of concepts.

What should a plate tectonics flashcard cover?

Focus on definitions such as divergent, convergent and transform boundaries, the processes they drive like subduction and seafloor spreading, and the evidence for continental drift. Asking how each process produces a landform helps you remember it.

Can I export my flashcards to Anki?

Yes, export to Anki is available on the Plus plan, which is $99.90 per year or $9.99 per 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 no credit card is needed to start. Students can get 40% off paid plans with a school email.
