StudyChamp helps students turn study material into something they can actually use. Take a photo of notes, textbook pages, handouts, or slides, and StudyChamp helps create a focused study pack with audio explanations, quizzes, flashcards, and reading practice. Instead of spending hours rewriting notes or building cards by hand, you can start from the material you already have and study it in different ways. What you can do with StudyChamp: • Create study packs from photos or uploaded pages • Review the main ideas in a clear, structured format • Listen to audio explanations when reading long text feels heavy • Test yourself with quiz questions based on your material • Practice active recall with flashcards • Use speed-reading mode to move through content in focused sessions • Share study packs with groups when you want to study with classmates • Keep packs private unless you choose to share them StudyChamp is built for students who learn better when information is not locked inside long blocks of text. Some learners understand more when they can listen. Some need questions. Some need quick visual prompts. StudyChamp gives the same material more than one path. Useful for: • Test preparation • Homework review • Class notes • Textbook chapters • Printed worksheets • Study groups • Quick revision before exams AI-generated study content should always be reviewed against your original material, teacher instructions, and official sources. StudyChamp is a study aid, not a replacement for your teacher, school, or course materials. StudyChamp is free to download. Creating AI study packs and using subscription credits requires an in-app purchase. You can still study packs shared with you directly or through groups.
