Why a custom PDF beats a generic flashcard set

A ready-made deck covers someone else's syllabus, so you end up studying the parts that match and skipping the parts your instructor actually tests. Converting PDF to flashcards using your own material keeps the study set tied to the readings and slides you were assigned.

  • Upload a PDF, DOCX, PPTX, text file or photo of a page as the source

Example climate and weather flashcards
What is the difference between weather and climate?Weather is the short-term state of the atmosphere at a given time and place, while climate is the average of those conditions over a long period, usually 30 years or more.
What causes the seasons on Earth?The tilt of Earth's axis, about 23.5 degrees, changes how directly sunlight strikes each hemisphere during the year, not the distance from the Sun.
What is the greenhouse effect?Gases such as carbon dioxide and water vapor absorb and re-radiate some outgoing infrared energy, keeping the surface warmer than it would be without them.
What is a cold front?The boundary where a mass of cold air moves under warmer air, often bringing a drop in temperature, a wind shift and sometimes thunderstorms.
What does relative humidity measure?How much water vapor the air holds compared with the maximum it could hold at that temperature, expressed as a percentage.

Works with your files

Upload PDFs, DOCX, PPTX, plain text notes or photos of pages. Photos are read with text recognition, so a snapshot of a handout works too.

Spaced repetition built in

Cards are scheduled so you see the ones you are shaky on more often, which makes review time count.

Quizzes and mind maps too

Turn the same PDF into multiple choice, true or false and short answer questions with explanations, or a mind map of the main ideas.

How it works

Upload your PDF

Drag in a textbook chapter, slide deck or lecture handout. No credit card is needed to start.

Review the generated cards

Check the questions and answers against the source, then edit or delete any card you do not need.

Study on a schedule

Work through the deck in the browser and let spaced repetition bring back the cards you are about to forget.

The process starts with the file you already have. The tool reads the text, pulls out terms, definitions and cause-and-effect points, and writes cards from them. You stay in control by reviewing each card before you study it, which catches any wording that drifted from the source.

Once the cards exist, the schedule does the rest. Spaced repetition shows you harder cards more often and easier ones less often, so a long chapter becomes a short daily habit instead of a last-night cram session.

Frequently asked questions

How many flashcards should I make from one PDF chapter on climate and weather?

Aim for one card per key term, cause and effect relationship or process, such as the greenhouse effect or how a cold front forms. Long chapters usually need more cards, but a deck you can review daily is more useful than a huge one you never open.

What is the best way to study weather and climate terms with flashcards?

Write the question on the front and a short answer that explains why on the back, so you practice reasoning rather than memorizing a label. Review the cards you miss on a schedule, and quiz yourself on the cards without looking first.

Can I export the flashcards to Anki or a PDF?

Yes, but exports are a paid feature. Plus, at $99.90/year or $9.99/month, includes PDF, DOCX, Anki and CSV export, while the free plan lets you study in the browser.

Does it work with a photo of a printed page?

Yes. Photos of pages are read with text recognition, so you can use a snapshot of a handout as the source. Check the generated cards against the page, since photos with glare or small print can be read less accurately.
