How AI flashcards fit into studying

Typing cards by hand from a 40-slide lecture deck takes longer than the review itself. Making flashcards using AI lets you start from the material your instructor actually used, so the cards match your course.

  • Upload PDFs, slides, DOCX files, notes or photos of pages
  • Review cards with spaced repetition in your browser
  • Check and edit any generated card before you study it
  • Export to PDF, DOCX, Anki or CSV on the Plus plan
Example intro biology flashcards (cell structure)
What is the function of the mitochondrion?It produces most of the cell's ATP through cellular respiration.

What is osmosis?The movement of water across a semipermeable membrane toward the side with higher solute concentration.
What does the nucleolus do?It assembles ribosomal subunits from rRNA and proteins.

How it works

Add your material

Upload a lecture PDF, a slide deck, pasted notes or a photo of a page.

Generate the cards

The AI pulls out key terms and questions and writes a front and back for each card.

Review on a schedule

Study the deck with spaced repetition, and edit any card that does not match your course.

Spaced repetition does most of the memory work, as long as the cards are short and specific. One fact per card, a clear question on the front, and an answer you can say from memory will do more for you than a long deck of vague prompts.

Regenerate a set after each lecture instead of waiting until exam week. Smaller decks are easier to keep up with, and the review sessions stay short enough to finish.

Frequently asked questions

How many flashcards should I make for one lecture?

A focused set covering one lecture or one chapter works better than one huge deck. Each card gets reviewed more often when the set stays small.

What makes a flashcard easier to remember?

Use one fact per card, ask a specific question on the front, and keep the answer short. Cards that ask why something happens often stick better than plain definitions.

Are exports included in the free plan?

No. Exports to PDF, DOCX, Anki and CSV are part of the Plus plan, which is $39/year or $7.99/month and includes unlimited generations. The free plan lets you study in the browser with 3 generations per month.

Can I upload photos of my notes or textbook pages?

Yes. Photos of pages are read with text recognition, and you can also upload PDF, DOCX, PPTX or plain text files.
