Study Slay is an AI note taker for students that turns lectures, documents and links into notes, flashcards and quizzes.
Students upload what they already have, including recorded lectures, MP3 or M4A audio, slide decks in PPT or PDF, Google Docs or Word notes, YouTube lecture links and web articles. Study Slay then produces structured Cornell-style notes, plus a searchable transcript with timestamps when the lesson is spoken.
Key features include multiple choice and short answer quizzes built from uploaded material, spaced repetition flashcards, and chat with an AI study companion called Leo, which answers questions with citations back to the exact slide or audio timestamp.
Leo can also break large syllabi into milestones, flag exam hints from spoken audio and quiz students at spaced intervals. Notes can be translated into more than 30 languages, and everything syncs between the web app and the native iOS app for iPhone and iPad.
The service covers STEM subjects such as calculus, organic chemistry, physiology and physics, as well as humanities, law cases and business case studies.
Pricing: a free plan includes one full study set of notes, flashcards and a quiz, five chat messages with Leo a day, lectures up to one hour and files up to 25 MB, with no credit card needed. Pro is billed at 99.99 dollars a year after a 3-day free trial and adds unlimited notes, quizzes, flashcards and chat, lectures up to four hours, files up to 100 MB, translation, exports and mastery tracking.
It is suited to high school and university students who want to turn lectures and readings into review material quickly.
