About this app
Tired of paying for multiple study apps that barely do the job? Big Brain puts everything you need into one powerful app — at a fraction of what others charge. Smart Notes — Write or paste your study notes, then let AI instantly summarize them into key points, generate flashcards, explain difficult concepts, rewrite for clarity, or fill in missing information. You can also snap a photo of handwritten notes or textbook pages and the AI will analyze the image and respond. All generated flashcards are automatically organized into decks for easy review later. AI HOMEWORK HELPER (3 free per day, unlimited with Pro) Stuck on a problem? Ask the AI tutor and get step-by-step explanations on any subject. You can even snap a photo of your homework and get instant help. NOTES TO PODCAST (Pro) Turn any study material into audio you can listen to on the go. Paste your notes, upload an image, or take a photo — Big Brain creates a podcast episode from it. AI-POWERED QUIZZES (3 free per week, unlimited with Pro) Generate quizzes on any topic in seconds. Choose from AI-generated questions or a built-in question bank across 12 subjects. Earn XP and track your scores. DOCUMENT ANALYZER (Pro) Paste any text — essays, articles, chapters, poems — and get a full summary, key details, Q&A breakdown, and even a practice quiz generated from it. FLASHCARDS Create your own flashcards free, or generate them automatically from your notes and quizzes with Pro. STUDY PLANNER (Free) Plan your week, set daily tasks, and stay on schedule.
