Flashcard maker that turns lectures into recall cards

Yes. Upload a lecture PDF, select the pages, and Recall Engine generates front and back flashcards automatically. Both text-based and scanned PDFs work.

One idea per card, a real question on the front, and a source you can verify. Recall Engine builds cards this way and links each to its lecture page.

Yes. Active recall flashcards are most effective when reviewed on a spaced schedule. Generate them once then re-test the cards you miss over increasing intervals.

You get 50 credits free on signup with no card required and credits are only used after a successful generation.

Yes for scanned lecture PDFs, including slides saved as images, since the maker reads the pages directly and pulls each card from what it sees. Pure handwriting can be hit or miss depending on how legible the scan is so very messy notes may produce weaker cards. Every card still links back to the source page so you can spot anything misread before you study it.

A general chatbot writes cards from memory and can quietly invent facts that were never in your lecture. This maker builds each card only from the pages you upload and ties it to the exact source page so you are revising your own syllabus rather than the model's best guess. That source link is also the fastest way to catch and bin a card that does not look right.

Yes. The cards are plain front and back recall prompts built from your own lecture content so they fit any course or exam style and they pair well with the SBA and MCQ practice you can generate from the same lecture. Treat them as a study aid for active recall rather than a source of clinical facts to quote and verify anything important against the linked source page.
