Why a custom deck beats a ready-made one

Most students who look for Quizlet-style practice already have the material they need: a lecture PDF, a chapter from a course reader, or a slide deck from the last session. Convert PDF to flashcards from that exact source and the cards match what your instructor will test, not a generic set someone else made.

Start from the PDF or slides your class actually uses
Edit or delete any card before you start studying
Use spaced repetition to focus on what you are likely to forget
Export to Anki, CSV, PDF or DOCX on the Plus plan

Example cell biology flashcards from a lecture PDF

Which organelle produces most of a cell's ATP?The mitochondrion, through cellular respiration.

What is the role of ribosomes?They synthesize proteins by translating mRNA into a chain of amino acids.

How does osmosis differ from diffusion?Osmosis is the movement of water across a semipermeable membrane, while diffusion is the movement of any solute down its concentration gradient.

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

What does the phospholipid bilayer of the cell membrane do?It forms a selectively permeable barrier that separates the inside of the cell from its surroundings.

Works with your own 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 intervals that help you remember them, so you spend time on what you are about to forget.

Study in the browser

Review your flashcards on any device with a browser. The free plan includes browser study with no exports.

How it works

Upload your material

Drop in a PDF, slides or notes. Nothing needs to be reformatted first.

Review the generated cards

Check the questions and answers, then edit or remove any card that does not match your course.

Study on a schedule

Work through the deck and let spaced repetition show you the cards that need another pass.

The workflow is simple. You upload the file, the AI pulls out key terms, definitions and facts, and you get a deck you can edit before studying. Keep the cards that test the ideas you find hard and delete the ones that repeat what you already know.

Frequently asked questions

How should I study flashcards made from a cell biology PDF?

Review the full deck in short sessions and say each answer aloud before you flip the card. Spend extra time on the cards you miss, since spaced repetition will bring them back sooner.

How many flashcards should I make from one lecture PDF?

Focus on the terms, definitions and facts your instructor emphasized rather than every line of the slides. A smaller deck of well-chosen cards is easier to finish and retain than a long one you skip.

Can I export my flashcards to Anki?

Yes, export to Anki is included on the Plus plan, along with PDF, DOCX and CSV export. The free plan lets you study in the browser without exports.

Is there a free plan?

Yes, the free plan includes 3 generations per month and browser study. No credit card is needed to start, and students get 40% off with a school email.
