What a flashcard app does

A flashcard app is software that shows one side of a card, such as a term, and asks you to recall the other side, such as its meaning. Checking yourself this way is more effective than rereading notes, because each recall attempt strengthens memory.

The front shows a term or question, and the back shows its meaning or answer.
Spaced repetition brings cards back at increasing intervals as you recall them.
Free plan: 3 generations per month with browser study.
Plus and Pro: export to Anki or CSV, and PDF or DOCX on Plus.

Example biology and vocabulary flashcards

MitochondrionAn organelle that produces most of a cell's ATP through cellular respiration.

PhotosynthesisThe process where plants use light energy to turn water and carbon dioxide into glucose and oxygen.

OsmosisThe movement of water across a semipermeable membrane from low solute concentration toward high solute concentration.

EphemeralLasting for a very short time.

Spaced repetitionReviewing material at increasing intervals so recall is strengthened just before it fades.

Flashcards from your files

Upload a PDF, slides, DOCX, plain notes or a photo of a page and get flashcards drawn from that material.

Spaced repetition

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

Export on Plus

Plus adds PDF, DOCX, Anki and CSV export so your cards can move into the tools you already use.

How it works

Upload your material

Add a PDF, slides, notes or an image of a page. Text recognition reads photos of pages.

Review the generated cards

Flip through the flashcards, check the terms and meanings, and study them in the browser.

Let the schedule adjust

Spaced repetition brings back the cards you struggle with at the right time before you forget them.

Most flashcard apps add spaced repetition, which schedules each card for review just before you would likely forget it. DeckOwl is an AI flashcard generator: upload your slides, notes or PDFs and it produces the cards for you, so you are not typing every definition by hand.

The free plan includes 3 generations per month and studying in the browser. Plus, at $39/year or $7.99/month, adds unlimited generations and PDF, DOCX, Anki and CSV export.

Frequently asked questions

What does a flashcard app actually do?

A flashcard app presents prompts, usually a term or question, and has you answer from memory before revealing the back. Many apps also track which cards you miss so you review them more often.

How often should I review flashcards to remember word meanings?

Short daily sessions work better than one long cram session, because spacing out review helps memory last. Spaced repetition schedules this for you so you review each card just before you would forget it.

How do I write good flashcards for definitions?

Keep one idea per card, put the term on the front, and write the meaning in your own words on the back. Cards that are too long or hold several ideas are harder to recall accurately.

Is the free plan enough to try it?

The free plan includes 3 generations per month and studying in the browser, with no credit card needed to start. Exports such as Anki and CSV require Plus or Pro.
