Works from PDFs, DOCX, PPTX, plain text and photos of pages read with text recognition
Spaced repetition schedules each card based on how well you recall it
Free plan includes 3 generations per month and browser study with no exports
Plus at $99.90/year or $9.99/month adds unlimited generations and Anki export

Example renewable energy flashcards for an Anki deck

How does a solar photovoltaic cell produce electricity?Sunlight excites electrons in a semiconductor, usually silicon, and the built-in electric field across the junction pushes them into an external circuit as current.

What is geothermal energy?Heat from Earth's interior, drawn from hot rock or water reservoirs, which can drive turbines to make electricity or heat buildings directly.

How does hydroelectric power generate electricity?Flowing water turns a turbine connected to a generator, most often at a dam where the water is released from a height.

What does capacity factor measure?The actual energy a plant produces over a period divided by the energy it would produce running at full nameplate capacity the whole time.

What is biomass energy?Energy released from organic material such as wood, crop residue or landfill gas, either by burning it or converting it into fuel.

Built from your own files

Upload PDFs, DOCX, PPTX, plain text notes or photos of pages, and get flashcards drawn from that material.

Spaced repetition

Cards come back at expanding intervals, so you review each one just before you would otherwise forget it.

Anki export on Plus

The Plus plan exports to Anki, along with PDF, DOCX and CSV, so your deck can live in the app you already use.

How it works

Upload your material

Add a PDF, slide deck, set of notes or photos of a page.

Review the cards

Check the flashcards DeckOwl creates and edit any that are unclear or incomplete.

Study or export

Study in the browser on the free plan, or export to Anki on Plus.

DeckOwl reads the file you give it, pulls out the definitions, causes and comparisons it finds, and turns them into cards with a question on the front and an answer on the back. You can review the set before studying, so you keep control over what ends up in your deck.

Spaced repetition then decides when each card returns. Cards you miss come back sooner and cards you know drift further apart, which keeps review time focused on the facts that still need work.

Frequently asked questions

How many flashcards should I make for a renewable energy unit?

There is no fixed number. Aim for one card per distinct fact, such as a definition, a mechanism or a trade-off between sources, and let the material decide how many you need.

What makes a good flashcard for studying energy sources?

Keep each card to one idea, phrase the front as a specific question, and put the key cause or figure on the back. Cards that compare two sources, such as solar and wind output variability, tend to help with exam questions.

Can I export my DeckOwl flashcards to Anki?

Yes, Anki export is part of the Plus plan, which costs $99.90/year or $9.99/month. The free plan lets you study in the browser but does not include exports.

What file types can I upload to create the deck?

You can upload PDF, DOCX, PPTX, plain text notes and images. Photos of pages are read with text recognition, and the free plan includes 3 generations per month.
