Astra AI is an AI study companion that turns your notes, slides and past papers into a personalized study plan, with lessons, quizzes, flashcards, podcasts and mock exams built from your own material. ### How is it different from ChatGPT? ChatGPT answers questions. Astra teaches: it knows your materials, tracks what you've mastered, plans your study sessions and never moves on until you understand. ### Does Astra teach from my own materials, or random content from the internet? From your materials. Upload your notes, textbooks or slides and every lesson, quiz and exam is built from exactly what you'll be tested on. ### Is it free to start, and what does it cost? You can start free, no card required. Premium unlocks unlimited tutoring, mock exams and podcasts for less per month than a single hour of private tutoring. ### Does it just give answers, or actually help me understand? It tutors step by step, asks you questions back and checks your understanding. The answer is the last thing you get, not the first. ### Who is Astra for: middle school, high school or university? All three. Astra adapts its explanations and difficulty to your level, from middle school all the way through university and professional exams. ### Which subjects and exams does it cover? Does one subscription cover them all? All major subjects: maths, sciences, languages, humanities, law and more. One subscription covers every subject and exam you add. ### Does it adapt to my level and pace? Yes. Astra continuously measures what you know, speeds up where you're strong and slows down where you struggle. ### Can Astra AI replace a private tutor? For most students, yes. It's available 24/7, infinitely patient and always prepared. ### How is it different from Photomath? Photomath solves a photographed problem. Astra uses that problem to teach you the method, so you can solve the next one yourself in the exam. ### How does the “+2 grades or your money back” guarantee work? Study consistently with your plan, and if your grade doesn't improve by at least two grades, we refund you in full. No forms, no fine print. ### Is my data safe? Yes. Your materials and conversations are private, never sold and never used to train ads. You can delete everything at any time. ## Start today.
