How an AI flashcard creator fits into studying

Most students already have the material they need, scattered across lecture slides, PDF readings and photos of whiteboard notes. An AI flashcard creator reads all of it and turns the key terms, definitions and facts into cards you can review in a few minutes a day.

Start with the chapter or lecture your next exam covers.
Check that each card has one clear answer before you study it.
Review cards you miss more often than the ones you already know.
Keep generating new decks as the course moves forward.

Example acids and bases flashcards

What is the pH of a neutral solution at 25 °C?7. Hydrogen ion and hydroxide ion concentrations are equal, each at 1 × 10⁻⁷ M.

What is an Arrhenius acid?A substance that increases the concentration of hydrogen ions (H⁺) in water.

What is a Brønsted–Lowry base?A substance that accepts a proton (H⁺) from another substance.

What is the conjugate base of HF?F⁻. It is the species left after HF donates a proton.

Name two strong acids.HCl and HNO₃. Strong acids dissociate almost completely in water, so their pH can be calculated directly from their concentration.

Works with the files you already have

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

Spaced repetition built in

Cards come back at the intervals where review is most useful, so you spend less time rereading and more time recalling.

Cards from your material only

Flashcards are generated from the content you upload, so the deck matches your course rather than a generic topic list.

How it works

Upload your material

Add a PDF, slides, notes or photos of a textbook page.

Generate your flashcards

The AI creates question and answer cards from the text it reads.

Study and review

Work through the deck in your browser and let spaced repetition bring back the cards you miss.

Flashcards work best when you write the answer from memory and then check it. A generated deck gives you a starting point, and you can still review it with the same habits you would use for handwritten cards, such as saying the answer aloud before you flip the card.

Because the cards come from your own files, the deck follows your instructor's emphasis. If a topic is missing or unclear, you can upload the next chapter and generate a new set.

Frequently asked questions

How many flashcards should I make for an acids and bases unit?

Aim for one card per term, definition or rule, which often means 40 to 80 cards for a unit. Start with the vocabulary and the core rules, then add cards for worked examples you keep getting wrong.

How do I study acid-base chemistry with flashcards?

Put the concept on the front and the reasoning on the back, such as the definition of a conjugate base or the reason a strong acid fully dissociates. Review the cards in short sessions and redo the ones you miss until you can explain them without looking.

Is there a free plan?

Yes. The free plan includes 3 generations per month and lets you study in the browser. No credit card is needed to start.

Can I export my flashcards?

Exports are a paid feature. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML export.
