Frequently asked questions
Are the biology flashcards free?
Yes. The biology flashcard demo is completely free with no signup. You can practice the deck as many times as you like.
What is spaced repetition and why does it matter for biology?
Spaced repetition schedules each card for review just before you would forget it. Biology has a lot of vocabulary and concepts that are easy to confuse — spaced repetition is one of the most evidence-backed ways to lock them into long-term memory.
Can I make flashcards from my own biology notes?
Yes. Sign up for free, upload your biology PDF, DOCX, or PPT, and Cuiz AI will generate a custom flashcard deck plus a matching quiz from the same material.
How are AI-generated flashcards different from Anki decks?
You get a starting deck in seconds instead of typing or downloading one. The cards are extracted directly from your source material, so they match exactly what you need to study. You can still review and refine them.
Will the flashcards work on mobile?
Yes. Cuiz AI works in any modern browser on phone, tablet, or desktop. No app install needed.
