How an AI flashcard generator helps you study

Students often end up with lecture slides, a textbook chapter and handwritten notes, all of which need to become cards before the next exam. An AI flashcard generator reads those files and drafts question-and-answer pairs you can check and adjust.

  • Upload PDFs, slides, DOCX, PPTX, notes or photos of pages
  • Review and edit every draft card before studying
  • Study with spaced repetition scheduled for you
  • Export to Anki or CSV on Plus, with no credit card needed to start
Example cell biology flashcards to study from
What organelle produces most of a cell's ATP?The mitochondrion, through cellular respiration.
What is the function of the Golgi apparatus?It modifies, sorts and packages proteins and lipids for transport.
What is osmosis?The movement of water across a semipermeable membrane from lower solute concentration to higher solute concentration.
What does the rough endoplasmic reticulum do?Its ribosomes make proteins that it folds and processes for secretion or for membranes.
How do eukaryotic cells differ from prokaryotic cells?Eukaryotic cells have a membrane-bound nucleus and membrane-bound organelles, while prokaryotic cells do not.

Works with your files

Upload PDF, DOCX, PPTX, plain text, notes or images. Photos of pages are read with text recognition.

Spaced repetition built in

Cards come back at the right intervals so you review what you are about to forget.

Quizzes and mind maps too

Turn the same material into multiple choice, true/false or short answer quizzes, or a mind map.

How it works

Upload your material

Add a lecture slide deck, a textbook chapter or your own notes.

Review the draft cards

Edit wording, delete weak cards or add your own before you study.

Study on a schedule

Work through due cards in the browser each day, and export to Anki or CSV on a paid plan.

Generating cards is only half the job. Spaced repetition brings each card back at increasing intervals, so terms you already know take less time and harder ones get more practice. Reviewing and editing the draft cards also helps you notice what the source material actually emphasizes.

Free accounts get 3 generations per month and can study in the browser. Plus adds unlimited generations and PDF, DOCX, Anki and CSV export, at $39 per year or $7.99 per month, with 40% off for students using a school email.

Frequently asked questions

How many flashcards should I make for a cell biology unit?

Aim for one card per key term, process or distinction, which often means 40 to 80 cards for a single unit. Cut any card that tests a detail you would not need on an exam.

What makes a good flashcard for memorizing terms?

Keep one fact on each card and write the front as a specific question, such as What does the Golgi apparatus do? Short answers are easier to review repeatedly than paragraphs.

Can I export my flashcards to Anki?

Yes, Anki export is available on the Plus plan at $39 per year or $7.99 per month. The free plan lets you study in the browser but does not include exports.

Is there a free plan?

Yes, the free plan includes 3 generations per month and browser study with spaced repetition. You do not need a credit card to start.
