How flashcards from notes work

Typed notes, lecture slides, and photos of handwritten pages can all become flashcards from notes in one upload. The tool pulls out terms, definitions, and key facts, then writes each as a short question with an answer on the back.

Works with typed notes, PDFs, DOCX, PPTX and photos of handwritten pages
Each card covers one fact so recall is quick and specific
Spaced repetition schedules reviews around what you forget
Free plan includes 3 generations per month with browser study

Example flashcards: periodic table groups

Which group are the alkali metals?Group 1 (except hydrogen), which have one valence electron and react vigorously with water.

Which group are the halogens?Group 17, which have seven valence electrons and readily form salts with metals.

What are the noble gases, and where are they?Group 18 elements such as helium and neon, which have full outer electron shells and are mostly unreactive.

What are the alkaline earth metals?Group 2 elements such as magnesium and calcium, which have two valence electrons and form 2+ ions.

Why do elements in the same group behave similarly?They share the same number of valence electrons, which largely determines how they bond with other elements.

Generate the full set

Any source works

Paste plain text, drop in a DOCX or PPTX, or photograph a page of handwritten notes. Text recognition reads the photo before cards are made.

Spaced repetition built in

Cards you miss come back sooner and cards you know fade into longer gaps, so review time goes to what you are actually forgetting.

Cards you can edit

Review the generated cards, cut the ones that are off, and add your own before you start studying.

How it works

Upload your notes

Choose a PDF, slide deck, DOCX, text file or image from your device.

Review the flashcards

DeckOwl drafts question-and-answer cards from your material. Keep the ones that matter and remove the rest.

Study on a schedule

Work through the deck in the browser. Spaced repetition decides when each card shows up again.

Good cards test one idea each. A card that asks for a single term is easier to recall than one that asks for a full paragraph, so the generated deck is meant as a starting point you can trim and reorder.

Because the cards come from your own material, the deck matches your course rather than a generic textbook. Re-upload updated notes before an exam and the new material can be added to your review.

Frequently asked questions

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

Aim for one card per group name, its typical properties, and one or two example elements, which usually comes to 20 to 40 cards for a unit. Cut any card you cannot explain in your own words yet.

What should a periodic table flashcard say on the back?

Keep one fact per card: the group name on the front, and on the back its group number, a key trait such as reactivity, and one member element. Short answers are easier to recall under spaced repetition.

Can I export my flashcards to Anki or CSV?

Yes, but exports are a paid feature. Plus at $7.99/month or $39/year includes PDF, DOCX, Anki and CSV export, while the free plan lets you study in the browser with 3 generations per month.

Do I need a credit card to try it?

No. You can start on the free plan without a credit card, and students get 40% off with a school email.
