What to look for in an AI flashcard app

AI apps that make flashcards save the most time when your study material already exists as slides, notes or a textbook chapter. Instead of writing every question by hand, you give the app your own pages and review what it produces.

Accepts the file types you actually study from, including scanned photos of pages
Keeps the original source close so you can verify each card
Schedules reviews with spaced repetition instead of a fixed list
Offers export to Anki or CSV if you want to study in another tool

Example biology flashcards (general study topic)

What is the powerhouse of the cell?The mitochondrion, which produces most of the cell's ATP through cellular respiration.

What does osmosis describe?The movement of water across a semipermeable membrane from lower solute concentration to higher solute concentration.

What is the difference between mitosis and meiosis?Mitosis produces two identical diploid cells, while meiosis produces four genetically varied haploid cells.

What is the role of ribosomes?Ribosomes translate messenger RNA into proteins.

What are the four nucleotide bases in DNA?Adenine, thymine, guanine and cytosine.

Generate the full set

Works from your files

Upload a PDF, DOCX, PPTX, text file or a photo of a page. Text in images is read with text recognition.

Spaced repetition built in

Cards resurface at growing intervals, so you spend time on the ones you are about to forget.

Export when you need it

Plus adds PDF, DOCX, Anki and CSV export. The free plan keeps studying in the browser.

How it works

Upload your material

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

Review the generated cards

Check the front and back of each flashcard and edit anything that needs fixing.

Study on a schedule

Work through the deck daily and let spaced repetition decide which cards come back next.

The quality of the cards depends on the source. Clear headings, defined terms and worked examples in your notes give the app more to work with, so check each card against the original before you rely on it.

Spaced repetition matters as much as generation. A deck you study once is forgotten quickly, while a deck that schedules reviews keeps material in memory over weeks.

Frequently asked questions

How many flashcards should I make for one topic?

Aim for one card per key term, definition or cause-and-effect relationship, which usually means 15 to 30 cards for a single lecture. Cards that test one fact each are easier to recall than long cards with several answers.

How often should I review flashcards with spaced repetition?

Review a little every day rather than cramming the night before an exam. Cards you get wrong should come back sooner, and cards you know well should appear less often.

Is there a free plan?

Yes. The free plan includes 3 generations per month and lets you study in the browser with no credit card needed. Exporting to PDF, DOCX, Anki or CSV requires Plus.

Can I export my flashcards to Anki?

Yes, but export to Anki is a paid feature included in Plus, which costs $39/year or $7.99/month. Students with a school email get 40% off.
