Gizmo

Gizmo is a flashcard and quiz app aimed at school and university students revising for exams such as GCSEs, A-levels and AP tests. Its premise is that the hard part of flashcards is making them, so most of the product is an AI import step: point it at a PDF, a PowerPoint, a YouTube video, typed notes, a recorded lecture or a photo of handwritten notes, and it writes a deck of cards and quiz questions from the material. Existing decks come across too — Gizmo imports sets from Quizlet and Anki — and there is a library of more than a million public decks made by other students.

Studying happens as short quizzes rather than flipping cards. Questions mix matching, multiple-choice and written answers, an AI tutor can explain what you got wrong, and the order and timing of reviews follow spaced repetition and active recall, so cards you know drift out of rotation while weak ones come back sooner. The app leans heavily on game mechanics to keep people coming back: XP, streaks, lives, speed bonuses, and leaderboards for friends and for your school, plus a social feed where classmates can follow each other and share decks. Decks can be organised into files by subject.

Gizmo runs on the web at gizmo.ai and as an iOS app, published by Gizmo AI Ltd. Making and studying flashcards is free, and a Gizmo Unlimited subscription sold inside the app removes the free tier's limits, with prices that vary by billing period and region.
