Why generate your own PDF flashcards

Printed study sheets are handy until you notice the deck was written for a different course. PDF flashcards built from your own lecture slides, readings and notes cover what your instructor actually tests, and you can export them as a PDF on Plus.

  • Cards come from your own material, not a generic deck
  • Photos and scans of pages are read with text recognition
  • Spaced repetition schedules reviews automatically
  • PDF, DOCX, Anki and CSV export on the Plus plan
Example renewable energy sources flashcards
Solar photovoltaic cellA device that converts sunlight directly into electricity using semiconductor materials such as silicon.
Capacity factor (wind turbine)The energy a turbine actually produces over a period divided by what it would produce running at full rated power the whole time.
Geothermal energyHeat drawn from beneath the Earth's surface to generate electricity or provide direct heating, available regardless of weather.
Hydroelectric damUses the energy of falling water to spin turbines and generate electricity, often with a reservoir that stores water for later use.
Biomass energyEnergy from organic material such as wood, crop residue or biogas, which counts as renewable when the material is replenished as it is used.
Generate the full set

Any source, one upload

Works with PDF, DOCX, PPTX, plain text, notes, and photos of pages read with text recognition.

Spaced repetition

Cards resurface at expanding intervals so your review time goes to the ones you are forgetting.

Export when you need print

Plus exports to PDF, DOCX, Anki and CSV. The free plan lets you study in the browser.

How it works

Upload your material

Add a PDF, slide deck, notes file or image of a page.

Check the generated cards

Compare questions and answers against your source before you start studying.

Study or export

Practice in the browser, or export a PDF on the Plus plan.

Upload a PDF, DOCX, PPTX, plain text file or a photo of a page, and the generator writes question-and-answer cards from that material. Spaced repetition then schedules reviews so the cards you miss come back sooner.

If you only need a quick study session, the free plan includes 3 generations per month and browser study, and no credit card is required to start.

Frequently asked questions

How many flashcards should I make for renewable energy sources?

Start with one card per key term, such as solar photovoltaic or geothermal, plus a few cards on how each source works and its trade-offs. Split a long chapter into several smaller decks so each one stays focused.

What should I know about renewable energy sources for an exam?

Know how each source generates electricity, its main limits such as the variability of solar and wind, and where it is used at scale. Exams often ask you to compare sources, so practice side-by-side trade-offs.

Can I print my flashcards as a PDF?

Yes, PDF export is included in the Plus plan, along with DOCX, Anki and CSV export. The free plan includes 3 generations per month and study in the browser without exports.

Do I need a credit card to start?

No, you can start on the free plan without a credit card. Students get 40% off Plus with a school email.
