Why keep your flashcards private

Shared study sets are handy, but your own class notes or private exam prep may not belong in a public library. Here is a simple way to think about how to make private flashcards from the material you already have.

Use your own lecture slides, notes or PDFs as the source.
Edit or delete any generated card before you study.
Study in the browser on the Free plan, with 3 generations per month.
Export to Anki or CSV on Plus if you want to move cards elsewhere.

Example cell biology flashcards (general study topic)

Which organelle produces most of a cell's ATP?The mitochondrion, through cellular respiration, because its inner membrane hosts the electron transport chain.

What is the main function of ribosomes?Protein synthesis. They read mRNA and link amino acids into polypeptide chains.

Why does the phospholipid bilayer act as a selective barrier?Its hydrophobic tails block charged and large polar molecules, so only small nonpolar molecules pass freely.

How does osmosis differ from diffusion?Osmosis is the movement of water across a semipermeable membrane, while diffusion is the general movement of any solute down its concentration gradient.

What does the Golgi apparatus do?It modifies, sorts and packages proteins and lipids into vesicles for transport to their destinations.

Built from your files

Upload a PDF, DOCX, PPTX, plain text notes or a photo of a page, and get flashcards made from that material.

Spaced repetition

Cards come back at spacing intervals so you review the ones you are about to forget, not the ones you already know.

Study in the browser

The Free plan includes 3 generations per month and browser study. Plus adds unlimited generations and exports to PDF, DOCX, Anki and CSV.

How it works

Upload your material

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

Generate your flashcards

DeckOwl reads the text and drafts question and answer cards from the content you chose.

Review and study

Edit any card you want, then study with spaced repetition in your browser.

Start with the source you control: a PDF from your course, your typed lecture notes or photos of a handout. Generating cards from that file means the deck reflects your class, not someone else's version of it.

Once the cards exist, review them on a schedule. Spaced repetition brings missed cards back sooner, which works better than rereading the same notes in one sitting.

Frequently asked questions

How many flashcards should I make for one topic?

Aim for one fact or question per card so each answer can be recalled in a few seconds. Most topics work well with 20 to 50 focused cards, and you can add more as you find gaps.

How often should I review flashcards with spaced repetition?

Review new cards daily at first, then let the spacing grow as you get answers right. Cards you miss should come back sooner, which is the point of the system.

Can I export my flashcards?

Yes, on the Plus plan, which costs $39/year or $7.99/month. Plus includes PDF, DOCX, Anki and CSV export, and unlimited generations.

Is there a free plan?

Yes. The Free plan includes 3 generations per month and studying in the browser, and you do not need a credit card to start. Students can get 40% off with a school email.
