Gizmo is a mobile-first AI learning app built to make studying addictive in a healthy way, combining proven learning science with gamified design. At its core, Gizmo lets students import almost any source material, whether a Quizlet or Anki deck, a YouTube video, a PDF, lecture notes, or a PowerPoint, and instantly transforms it into AI-generated flashcards. The app can also scan handwritten notes and convert them into flashcards and quizzes, removing the tedious manual work that usually stands between students and effective review.
The learning model leans on two well-established techniques: spaced repetition and active recall. Rather than passively rereading, students answer quick quizzes timed to resurface material right before they would forget it, strengthening long-term retention. Gizmo wraps these methods in a game-like experience with streaks, rewards, and fast-paced quizzing, so the act of studying feels engaging rather than like a chore. The result is a tool designed to build a daily study habit.
Gizmo has grown into a large consumer education platform, reporting roughly 13 million users and offering access to a library of more than one million free public flashcard decks created by students. It is available on both iOS and Android, making it easy for learners to review on the go and sync across devices. The breadth of import options and the community deck library lower the barrier to getting started for any subject.
In April 2026, Gizmo announced a $22 million investment, with the round led by Shine Capital and participation from Ada Ventures, Seek Investments, GSV, and NFX, which had previously led the company's $3.5 million seed round. The capital supports continued growth of its user base and expansion of its AI-powered study features.
Gizmo is best suited for students and lifelong learners who want a fast, engaging way to memorize and master material across any subject. By pairing AI content generation with spaced repetition and game mechanics, Gizmo bets that the path to better learning outcomes runs through making study sessions genuinely fun to return to.
