How an AI flashcard generator turns your material into cards

Students who want an AI flashcard generator usually have a stack of lecture slides, a chapter PDF and a page of messy notes, and no time to write cards by hand. An AI flashcard generator reads that material, picks out the terms, definitions and processes worth remembering, and drafts a card for each one.

Works from your own PDFs, DOCX files, PPTX slides, plain notes and photos of pages
Spaced repetition schedules reviews based on how well you recalled each card
Free plan includes 3 generations per month and browser study
Plus adds unlimited generations and PDF, DOCX, Anki and CSV export

Example intro biology flashcards on cell structure

Which organelle produces most of the cell's ATP through cellular respiration?The mitochondrion, which converts energy from nutrients into ATP.

What is the main job of the Golgi apparatus?It modifies, sorts and packages proteins and lipids for transport within or out of the cell.

What structure controls what enters and leaves the cell?The plasma membrane, a phospholipid bilayer with embedded proteins that regulate transport.

Which two organelles contain their own DNA?Mitochondria and chloroplasts, which is consistent with their evolutionary origin from bacteria.

How do eukaryotic cells differ from prokaryotic cells?Eukaryotic cells have a membrane-bound nucleus and membrane-bound organelles, while prokaryotic cells do not.

Generate the full set

Reads your files

Works from PDF, DOCX, PPTX, plain text and images. Photos of pages are read with text recognition.

Spaced repetition built in

Cards you miss come back more often, so review time goes to the material you are most likely to forget.

Quizzes and mind maps too

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

How it works

Upload your material

Add a PDF, slide deck, set of notes or a photo of a textbook page.

Review the generated cards

Check the flashcards, edit anything that is off, and keep the ones you want to study.

Study on a schedule

Practice in the browser with spaced repetition, and export to Anki or CSV on a paid plan.

The useful part is what happens after the cards exist. Spaced repetition schedules each card based on how well you recalled it, so terms you already know appear less often and the ones you keep missing come back sooner. You can check every card before studying, which keeps the deck tied to what your instructor actually covered.

Frequently asked questions

How should I split a chapter into flashcards?

Use one fact, term or process per card rather than a paragraph on the back. Prioritize definitions, causes and effects, and anything your instructor repeated in lectures.

What is the best way to study flashcards so they stick?

Say the answer aloud or write it out before you flip the card, then rate how easily you recalled it. Spaced repetition handles the timing, so short daily sessions work better than cramming.

Can I export my flashcards to Anki?

Yes, export to Anki is available on the Plus plan, along with PDF, DOCX and CSV export. The free plan lets you study in the browser but does not include exports.

Is there a free plan to try the AI flashcard generator?

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