Snap a photo of whatever you are stuck on. AI Teacher explains it at your level, then turns it into practice questions so it actually sticks. AI Teacher reads textbook pages, worksheets, past papers, handwritten notes and screenshots with advanced OCR, then explains them at the difficulty you choose. It is not a shortcut for copying answers - it is built to make you understand. 1. Snap - photograph a textbook, worksheet, note or screenshot, or pick an image from your gallery 2. Understand - choose Simple, Standard or Detailed and read the explanation 3. Remember - answer the practice quiz, save it to your own study book and review it later WHAT YOU CAN DO - Explain from a photo - textbooks, worksheets, exercise books, handwritten notes, screenshots - Choose your difficulty - Simple, Standard or Detailed, from a short summary to university-level depth - A second angle - did not click the first time? The same topic explained a different way - Auto-generated quizzes - multiple choice or written answers, with instant feedback - Ask follow-ups - keep asking "but why?" until it makes sense - Your own study book - saved explanations become a PDF book with a table of contents you can reread and download - Review calendar - every "read" and "memorized" is logged, so you can see what to review and when - History and bookmarks - nothing you have asked is ever lost SUBJECTS Math, algebra, geometry, English, languages and translation, physics, chemistry, biology, earth science, history, geography, economics, essay writing and more. If you can photograph it, AI Teacher can explain it. WHO IT IS FOR - Students who got the right answer but still do not understand the method - Anyone who missed the chance to ask a teacher and has to sort it out at home - Parents helping with homework they have not studied in twenty years - Exam review - check the key points in minutes instead of rereading whole chapters - Adult learners going back to study, or working through a certification textbook WHY STUDENTS USE IT - An explanation alone is not enough - reading feels like learning, but it fades within days, so every explanation is followed by practice questions - Active learning - the loop between taking information in and putting it back out is what turns understanding into memory - Save hours - clear a doubt in seconds instead of searching - Your progress is recorded - reads and "memorized" counts add up, so nothing slips through the cracks FREE AND PREMIUM AI Teacher is free to use every day. When your free runs are gone you can watch a short ad for one more. Premium removes the limit and the ads, and adds High-Precision Mode, longer input (up to 1000 characters), three photos read at once, more follow-up questions and unlimited pages in your study books. Choose monthly or annual - annual saves the most.
