Biology flashcards maker

Studying cell biology, genetics, ecology or physiology? Paste your lecture notes or a textbook passage and your own Claude turns it into clean biology flashcards — questions, definitions and cloze deletions — free and without a login. Because generation runs through your Claude instead of our servers, there is no monthly card cap, and you can export the deck to Anki (.apkg) or save it to StudyCards to review with spaced repetition.

Example biology notes to paste

The mitochondrion is the site of aerobic respiration and produces ATP via oxidative phosphorylation across the inner membrane. The Krebs cycle takes place in the mitochondrial matrix. Chloroplasts perform photosynthesis, using chlorophyll in the thylakoid membranes to convert light energy into glucose. Prokaryotic cells lack membrane-bound organelles; eukaryotic cells have a true nucleus.

Frequently asked questions

Can it handle diagrams and processes like the Krebs cycle?
It works from the text you paste, so describe the process in your notes and it will produce step and definition cards. Add any diagram images inside StudyCards or Anki after generating the cards.
Is it good for AP Biology or first-year university?
Yes. Paste the section you’re revising — cell biology, genetics, ecology, human physiology — and you get cards pitched at the level of your source text, from AP through undergraduate.
Is there a limit on the number of cards?
No. Your own Claude does the generation, so there’s no per-card cost and no paywall — make as many biology decks as you need.
