An AI tutor that draws every step of the answer on a whiteboard
Every answer is drawn out live on the board — graphs, diagrams, arrows and step-by-step working — while the tutor narrates what it is doing.
Rather than dumping the answer, the tutor guides you one hint at a time and checks your reasoning so you can solve the next problem alone.
Upload a study guide, PDF or slides and it becomes a structured run-through of key points, common traps and a short quiz.
The tutor speaks and writes on the board in English, Chinese, Spanish, French, German, Italian, Portuguese, Japanese, Korean and Malay, switchable mid-lesson.

Turn any question into a personalized animated lesson in seconds
Type a math or STEM question and VideoTutor assembles an animated scene with a narrated, step-by-step explanation in real time.
Interrupt the video at any moment to ask a follow-up or redirect the explanation, without breaking the flow of the lesson.
The agent captures session interactions, extracts learning signals and updates memory so teaching adapts to the individual student over time.
Built for SAT and AP preparation as well as core STEM, language and general K-12 topics, with worked solutions shown the fastest way.
