Why flashcards is one word, and where flash cards still shows up

When you search whether flashcards is one word or two, the answer is one: the closed form flashcards is standard in Merriam-Webster and most style guides, while the two-word flash cards appears mostly in older books and some print headings.

Use flashcards as the standard one-word spelling in essays and course materials.
Keep one fact per card so each answer can be checked quickly.
Review cards you missed more often than cards you already know.
Check every generated card against your source before relying on it.

Generate your flashcards

DeckOwl writes question and answer cards from the content you provided, so you can check them before studying.

Study with spaced repetition

Review in the browser on a schedule that brings back the cards you are most likely to forget.

Either spelling refers to the same thing, a small card with a prompt on one side and an answer on the other. What matters more for studying is the quality of the cards, so each one should test a single idea.

If you already have class notes or a textbook chapter, you can skip writing cards by hand and generate a first draft from that material, then edit the wording to match how your course asks questions.

Frequently asked questions

How many flashcards should I make for a biology unit?

There is no fixed number, but most chapters work well with a card for each key term and each process you need to explain. Start with the vocabulary and add cards as you find gaps.

What is the best way to study cell biology flashcards?

Read the front, say the answer aloud before flipping, and mark it as known or missed. Spaced repetition then brings back the missed cards more often.

Can I export my flashcards to Anki or a CSV file?

Yes, but exports are a paid feature. Anki and CSV export are included in the Plus plan, and the free plan lets you study in the browser.

Can DeckOwl read photos of my notes?

Yes. Images such as photos of pages are read with text recognition, and the text is turned into flashcards just like a PDF or DOCX file.
