Why build your cards from your own notes

Typing cards by hand is where many study sessions lose their momentum before any review starts. DeckOwl takes your own material and writes the first set of cards, so you can use this Anki cards app to start reviewing sooner.

Start with the terms and definitions your course emphasizes, then add cards for gaps you miss in review.
Keep each card to one idea so the answer is clear at a glance and easy to grade yourself.
Review daily for short sessions rather than cramming a full deck the night before an exam.
Use exports on the Plus plan if you want the same cards in Anki on another device.

Example climate and weather flashcards

What is the difference between weather and climate?Weather is the short-term state of the atmosphere at a place and time, while climate is the average of those conditions over at least 30 years.

What causes the seasons on Earth?The planet's axial tilt of about 23.5 degrees, which changes how directly sunlight strikes each hemisphere through the year.

What is the greenhouse effect?Gases such as carbon dioxide and water vapor absorb outgoing infrared radiation and re-emit some of it back toward the surface, warming the planet.

What weather is usually associated with a high-pressure system?Descending air, which tends to suppress cloud formation and bring clear, stable conditions.

What does El Niño do to Pacific surface waters?It warms the central and eastern tropical Pacific, which shifts rainfall and temperature patterns in many parts of the world.

Generate the full set

Cards from your own material

Upload PDFs, PPTX slides, DOCX files, plain notes or photos of pages. Text in images is read with text recognition, so handwritten-free printed pages work too.

Spaced repetition built in

Cards come back on a schedule based on how well you remembered them, so you spend less time rereading cards you already know.

Export when you need it

On Plus, export your deck to Anki, or to PDF, DOCX or CSV. The free plan keeps studying in the browser.

How it works

Upload your material

Add a PDF, slide deck, document, text file or photo of a page from class or a textbook.

Review the generated cards

Check the flashcards DeckOwl writes, edit any that are unclear, and remove the ones you do not need.

Study on a spaced schedule

Review in the browser each day, and export to Anki on Plus if you prefer that app for reviews.

Generated cards are only as useful as the source, so upload the slides or chapter your instructor actually covers. Then edit the wording so each card asks for one fact you can check against your notes.

Frequently asked questions

How many flashcards should I make for a climate and weather unit?

Aim for one card per term or fact you need to recall, which often means 30 to 60 cards for a single chapter. Add more as your review shows which ideas keep slipping.

How often should I review flashcards with spaced repetition?

Review each card when it is scheduled rather than all at once. Cards you miss come back sooner, and cards you know are spaced further apart.

Can I export my cards to Anki?

Yes, export to Anki is included on 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.

Is there a free plan?

Yes, the free plan includes 3 generations per month and browser study. No credit card is needed to start, and students get 40% off with a school email.
