How PDF flashcards work in DeckOwl

Your lecture PDF already contains the terms you need to memorize, so Quizlet-style flashcards from PDF can be generated straight from that file instead of retyping every definition by hand.

Upload PDFs, slides, notes, or page photos in one place.
Edit generated cards before you start studying them.
Review on a spaced repetition schedule in the browser.
Export to Anki, CSV, PDF, or DOCX on Plus.

Example electric circuits flashcards

What is Ohm's law?Voltage equals current times resistance, written as V = I × R.

How does current behave in a series circuit versus a parallel circuit?In series, current is the same through every component; in parallel, voltage is the same across each branch and current splits between them.

What is electric power in a DC circuit?Power equals voltage times current, P = V × I, measured in watts.

What does Kirchhoff's current law state?The sum of currents entering a junction equals the sum leaving it, because charge is conserved at a node.

What does a capacitor store in a circuit?Electric charge and energy in the electric field between two conductors separated by an insulator.

Generate the full set

Any file you already have

Upload PDFs, DOCX, PPTX, plain text notes, or photos of pages. Text recognition reads the images so handwritten-then-typed notes still work.

Spaced repetition built in

Cards you miss come back sooner and cards you know fade into longer intervals, so study time goes to the material that needs it.

Export when you need it

Plus and Pro plans export to Anki, CSV, and PDF or DOCX. The Free plan keeps you studying in the browser.

How it works

Upload your PDF

Add the file from your class, textbook chapter, or lecture deck.

Review the generated cards

Check the questions and answers, edit anything that does not match your course, and keep the ones that matter.

Study or export

Review in the browser with spaced repetition, or export to Anki on a paid plan.

DeckOwl reads text from PDFs, DOCX, PPTX, plain notes, and photos of pages, then writes question-and-answer cards you can review in the browser. Spaced repetition schedules each card so the ones you miss come back sooner.

A deck from someone else's file only matches that file. Building your own from the PDF your instructor actually used keeps the wording, terms, and examples you will be tested on.

Frequently asked questions

How many flashcards should I make from an electric circuits chapter?

Aim for one card per defined term, law, or formula, which usually works out to roughly 20 to 40 cards for a single chapter. Cut any card you can answer from memory in a few seconds, since it adds little review value.

Which circuit concepts are easiest to get wrong on flashcards?

Students often mix up series and parallel behavior, so write cards that ask what stays the same in each case, such as current in a series loop or voltage across parallel branches.

Can I export these flashcards to Anki or as a PDF?

Exports are a paid feature: Plus includes PDF, DOCX, Anki, and CSV export. The Free plan lets you study in the browser but does not include exports.

Is there a free plan to try it first?

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