The must-have study app for high school and college. Add your class material or record a lecture, and AI makes your summaries, flashcards, quizzes and practice tests. ADD WHAT YOU HAVE Photograph your notes or a handout, or add a PDF, slides, a class recording, a YouTube lecture or a blank note. Each one opens right away as its own material, and AI fills it in unit by unit. Keep related materials in a folder. Your PDF summarizer, quiz maker, test maker and lecture recorder in one app. AI SUMMARIES Each material gets a clear summary by unit: study notes with page chips back to the source. The summary is yours to edit, or ask for a rewrite, with Undo. AI PRACTICE TESTS Add last year's test and yours follows its sections, question types, marks and time, with new questions from your notes. Each written answer is marked against every point of its scoring guide, with what you left out and a model answer. Exam prep from your own material: every practice test comes as a real paper, with multiple choice, short answer and written questions, each with its points. No past test? Pick your exam (AP, SAT, IB or your school's own test) and the questions follow its question types. Build one test across several materials. RECORD A LECTURE, GET THE SUMMARY Record a lecture where recording is allowed. When it ends, it becomes a summary and flashcards. A YouTube lecture link works too. AI QUIZZES AI writes a quiz from each material, with new questions rather than your cards again. Retake it as often as you like. AI FLASHCARDS Every material gets key terms and flashcards from what's on the page. Press start, stop anytime and continue where you left off. Or play them as Blocks or Match. A word list becomes word cards with meanings and examples. AI TUTOR Ask anything. The AI tutor knows the material you're in, and any you attach. MISTAKES Missed questions from practice tests, quizzes and blurting gather in Mistakes. Retry them, or try new questions on the same points; two right answers on different days clear one. BLURTING Pick a unit and write what you remember, typed or on paper. It's checked against your summary, and what you left out is pointed out. PODCAST Two AI voices talk your material through. Full episodes are Pro; Free gets one short listen a week. SPACED REPETITION, IF YOU WANT IT Turn on spaced repetition for a material and FSRS brings each card back just before you'd forget it. Cards to review gather in Review, and you choose how many new cards a day. Add a test date and you get reminders 7, 3 and 1 days before. ALSO INCLUDED A streak, a class link classmates can study without an account, dark mode and data export. Works on iPhone and iPad, with Home Screen widgets. No ads. FREE AND PRO Free: 2 uploads a week (a batch of photos or a PDF, a recording or a YouTube lecture), 2 practice tests a week and 20 AI tutor messages a day; each material's quiz comes with it, retaken as often as you like; new rounds share the week's 2 practice tests. Studying everything you've made is free and unlimited. StudyLess Pro adds far more each month: 150 uploads, 100 practice tests, 1,500 AI tutor messages, 40 podcast episodes and 30 hours of recording a month, within the fair-use limits in our Terms (lower during a free trial). Pro is an auto-renewing subscription: in the US, $49.99 a year with a 7-day free trial for new subscribers, or $9.99 a month. Prices vary by country; the App Store shows yours, in your currency, before you buy. Payment is charged to your Apple Account when the free trial ends, or at confirmation of purchase without a trial. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; manage or cancel it anytime in your App Store account settings. StudyLess uses AI, which can make mistakes: check its work against your material.
