Sina: AI Tutor & Homework Help

About

Turn a homework question into an animated video lesson with Sina. Take a photo of a question from your school subjects, then watch and listen as Sina explains the reasoning step by step. WATCH AND LISTEN TO A VIDEO LESSON Each lesson combines an animated board with spoken explanations. See the solution develop while you hear the reasoning. Pause, replay, or move between steps to learn at your own pace. SEE EACH STEP Follow equations, handwritten explanations, highlights and visual cues. Understand how the solution develops from the question to the answer. START WITH A PHOTO Capture a question with your camera or choose an image from your photo library. Work across your school subjects: math and geometry, physics, chemistry, biology, history, geography and languages. Follow calculations, concepts and explanations in a visual lesson. UNDERSTAND YOUR MISTAKES Upload your own working with the question in Find My Mistake mode. Explore where your approach went wrong and learn the reasoning behind a correction. ASK ABOUT A STEP Open a step's explanation and ask a follow-up question by typing or using optional voice input. Get help with the part you want to understand. PRACTICE WITH GUIDANCE Learning Mode guides you through a question with prompts and hints. Try a step yourself, ask for help, and work toward the solution.
