From slide deck to study deck

Lecture decks are packed with terms, diagrams and captions, but they are not built for review. A PowerPoint-to-flashcards workflow turns each key idea into a question you answer from memory, which is far more effective than rereading slides.

  • Accepts .pptx files, PDFs, DOCX, plain notes and photos of slides
  • Spaced repetition schedules the cards you miss more often
  • Study in the browser on the Free plan with 3 generations a month
  • Plus adds unlimited generations and Anki or CSV export
Example ecosystem and food web flashcards
What is a producer in a food web?An organism, usually a plant or alga, that makes its own food from sunlight or chemical energy.
What is the difference between a food chain and a food web?A food chain is a single path of energy flow, while a food web shows many interconnected chains within one ecosystem.
What does a trophic level describe?The position an organism occupies in a food chain, such as producer, primary consumer or secondary consumer.
Why does less energy reach higher trophic levels?Only about 10 percent of energy passes to the next level, and the rest is lost mostly as heat through metabolism.
What role do decomposers play in an ecosystem?Bacteria and fungi break down dead matter and return nutrients such as nitrogen and carbon to the soil.

Reads your slides

Upload a .pptx file and DeckOwl pulls the text from each slide, including bullet points and captions.

Spaced repetition

Cards you miss come back sooner, so review time goes to the terms you are actually forgetting.

Photos work too

If you only have pictures of projected slides, text recognition reads them and turns them into cards.

How it works

Upload your deck

Drop in a PowerPoint file, or add PDFs, notes or photos of the slides.

Generate your cards

DeckOwl writes question and answer flashcards from the key ideas on each slide.

Review on a schedule

Study in the browser and let spaced repetition bring back the cards you find hardest.

Upload the .pptx file and DeckOwl reads the text on each slide, including bullet points and short captions. You then review the cards with spaced repetition, so the terms you miss come back sooner.

If your instructor only shared photos of the projector screen, images work too, since text recognition reads them. Check the cards against the original slides before an exam, and delete any that restate something trivial.

Frequently asked questions

How many flashcards should I make from one slide deck?

Aim for one card per key term or cause-and-effect idea, which is usually 15 to 30 for a typical lecture deck. Cut any card that asks about something you already know well.

How do I study food web vocabulary effectively?

Quiz yourself on each term before checking the answer, then sketch a small food web from memory to see how the roles connect. Spaced repetition brings the hard terms back more often than the easy ones.

Can I export the flashcards to Anki?

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

Does it work with photos of slides?

Yes, photos of slides are read with text recognition, so you can work from a picture if the original file is unavailable. Check the generated cards against the slides before a major exam.
