Why making flashcards by hand slows studying down

Typing every card by hand is the slow part, so the fastest answer to how to make flashcards app questions is to let the app read your material and draft the cards for you.

Example periodic table groups flashcards
Which group contains the alkali metals?Group 1, excluding hydrogen, which is usually placed separately. These metals have one valence electron and react strongly with water.
What are the elements in group 17 called?Halogens. They need one more electron to fill their outer shell, so they readily form -1 ions.
Why are group 18 elements called noble gases?Their outer electron shell is full, so they rarely form compounds and are mostly found as single atoms.
What are the group 2 elements called, and how many valence electrons do they have?Alkaline earth metals, with two valence electrons that they lose to form +2 ions.
Why are groups 3 to 12 called transition metals?They are the d-block elements, with partly filled d orbitals that often give their compounds color.

Works from your material

Upload PDFs, PowerPoint slides, DOCX files, plain text notes or photos of pages. Photos are read with text recognition.

Spaced repetition built in

Cards you find hard come back sooner, and cards you know well are spaced further apart, so review time goes where it helps.

Study anywhere

The free plan lets you study in the browser with 3 generations per month. Plus adds unlimited generations and exports.

How it works

Upload your material

Add a PDF, slide deck, document, text file or photo of your notes. No credit card is needed to start.

Review the generated cards

Check the flashcards DeckOwl drafts, then edit or remove any that do not match what your course covered.

Study on a schedule

Work through the deck in the browser. Spaced repetition decides when each card returns based on how well you recalled it.

A good card asks one clear question with one clear answer. When the source is your own lecture slides or textbook pages, the cards stay tied to what your instructor actually teaches, which makes review more useful than a generic deck.

You still need to check the output. Remove duplicates, fix anything that does not match your notes, and add cards for ideas that matter most before your exam.

Frequently asked questions

How many flashcards should I make for a periodic table unit?

Start with the main group names and their defining traits, which is usually 15 to 25 cards for one unit. Add more only after you can recall those reliably.

Is it better to memorize periodic table groups by pattern or by list?

Learn the pattern first, such as how many valence electrons each group shares, and then drill the names. Cards that ask why a group behaves a certain way tend to stick better than name-only cards.

Can I export these flashcards to Anki?

Yes, but export is a paid feature. Anki, PDF, DOCX and CSV export are included in Plus at $99.90/year or $9.99/month, while the free plan is for studying in the browser.

Does DeckOwl work from photos of pages?

Yes. Photos of pages are read with text recognition, so you can upload a picture of your notes or a textbook page.
