How an Anki deck is organized

An Anki deck is a collection of flashcards grouped by topic, where each card has a front (a term or question) and a back (the answer). The free Anki app schedules each card for review so that harder cards appear more often than easy ones.

  • A deck is a group of cards, usually built around one course unit or topic.
  • Each card has a front prompt and a back answer that you check against yourself.
  • Spaced repetition decides when each card returns based on how well you recalled it.
  • Decks can be exported to Anki on a Plus plan, or studied in the browser on the free plan.
Example periodic table groups flashcards
What are the Group 1 elements (excluding hydrogen) called?Alkali metals. They have one valence electron and react vigorously with water.
What are the Group 2 elements called?Alkaline earth metals. They have two valence electrons and typically form 2+ ions.
What are the Group 16 elements called?Chalcogens, such as oxygen and sulfur. They have six valence electrons and often form 2- ions.
What are the Group 17 elements called?Halogens, such as chlorine and fluorine. They have seven valence electrons and form 1- ions.
What are the Group 18 elements called?Noble gases. Their full outer electron shells make them largely unreactive.

Cards from your own material

Upload PDFs, DOCX or PPTX files, plain notes, or photos of pages read with text recognition.

Spaced repetition built in

Cards come back at the intervals where you are most likely to forget them, so review time goes to the material you need.

Export when you need it

Plus members can export to Anki, along with PDF, DOCX and CSV files.

How it works

Upload your study material

Add a lecture PDF, a slide deck, typed notes or a photo of a textbook page.

Review the generated cards

Check the front and back of each flashcard and remove anything you do not need.

Study or export your deck

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

A deck works best when each card tests one idea. Splitting a chapter into several small decks, such as one for each unit or exam topic, keeps review sessions short and focused.

DeckOwl builds the deck for you from your own material, so the cards match what your instructor covered rather than a generic list.

Frequently asked questions

How many flashcards should I make for the periodic table groups?

Aim for one card per group name, one per key property, and a few for common ion charges, which keeps the set to about 15 to 25 cards. Add more only where you keep missing answers.

What is the best way to memorize the periodic table groups?

Study the group names and their valence electron counts together, then quiz yourself on examples from each group. Reviewing the cards on a spacing schedule helps the pattern stick for an exam.

Is an Anki deck free to create with DeckOwl?

The free plan includes 3 generations per month and studying in the browser. Exporting to Anki requires a Plus plan, which costs $99.90 per year or $9.99 per month.

Do I need a credit card to try DeckOwl?

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