Gizmo turns your PDFs, notes, slides and YouTube videos into AI-generated flashcards and quizzes, with leaderboards and study games to keep you coming back. Space Repeat takes the opposite approach: you write your own cards, and a calm, distraction-free review schedules each one right before you'd forget it. Here's how they compare.

Gizmo is the faster way to get from a PDF or lecture video to a deck, and its games and leaderboards suit learners who are motivated by competition. Space Repeat suits learners who want to understand and own their material: you write each card, and there are no leaderboards or games competing for your attention, just reviews timed to your memory.

Yes. Gizmo describes itself as using spaced repetition and active recall. Both apps schedule reviews; the main difference is that Gizmo's AI writes most of your cards, while in Space Repeat you write them yourself.
Because writing the card is part of learning. Deciding what matters and putting it in your own words is effortful processing that AI generation skips, and it keeps every card matched to what you actually need to know.
