Making biology flashcards from your own material

A biology flashcard maker is most useful when it reads the exact chapter or lecture you are studying, because the terms on your card should match your instructor's wording. Upload the slides or notes from a unit on cell structure, genetics, or ecology and the tool proposes a card for each key term, process, or structure it finds.

Generate cards from lecture PDFs, slides, notes, or photos of textbook pages
Keep one term or process per card so review stays focused
Use spaced repetition so weak cards return more often
Edit any card before studying to match your course wording

Example biology flashcards

What is the function of mitochondria?They produce most of the cell's ATP through cellular respiration.

What does osmosis describe?The movement of water across a semipermeable membrane from low solute concentration to high solute concentration.

What is the difference between mitosis and meiosis?Mitosis produces two genetically identical diploid cells, while meiosis produces four genetically varied haploid gametes.

What is the role of RNA polymerase?It synthesizes RNA from a DNA template during transcription.

What happens in the light-dependent reactions of photosynthesis?Light splits water, releasing oxygen and producing ATP and NADPH.

Generate the full set

Starts from your own material

Upload PDFs, DOCX or PPTX files, plain-text notes, or photos of pages. Text in images is read with text recognition.

Spaced repetition built in

Cards come back at growing intervals, so you review terms just before you are likely to forget them.

Study in the browser or export

The free plan lets you study in the browser. Plus adds PDF, DOCX, Anki and CSV export for printing or other apps.

How it works

Upload your biology material

Add a lecture PDF, slides, typed notes, or a photo of a textbook page.

Review the generated cards

Check the front and back of each flashcard and edit anything that is unclear or too long.

Study on a spaced schedule

Work through the deck daily. Cards you miss come back sooner, and cards you know move further out.

Good biology cards usually test one idea each. A card asking what the Krebs cycle produces is easier to recall than one that asks you to list everything about cellular respiration. Edit the generated cards to keep each answer short, then let spaced repetition bring back the ones you miss.

Once the deck is built, short daily sessions work better than long cramming sessions. Export to Anki or CSV on a paid plan if you want to continue in another app.

Frequently asked questions

How many flashcards should I make for a biology unit?

Aim for one card per key term, process, or structure rather than a fixed number. A single chapter often yields a few dozen cards, and you can add more as review shows where you have gaps.

What makes a good biology flashcard?

Write the front as a specific question, such as what the role of ribosomes is in protein synthesis, and keep one idea per card. Avoid copying long textbook passages onto the back.

Can I export biology flashcards to Anki or CSV?

Yes, but exports are a paid feature. The Plus plan includes PDF, DOCX, Anki and CSV export, while the free plan lets you study cards in the browser.

Is there a free plan?

Yes. The free plan includes 3 generations per month and browser study, and no credit card is needed to start. Students with a school email get 40% off paid plans.
