Videotutor is an AI video tutor and AI education tool that takes a math or STEM question, including one you upload as a photo, and turns it into a short animated explainer with voice-over. It's built for K-12 students, SAT and AP test takers, and anyone who learns better by watching a worked solution than reading one. You type a question or drop in a screenshot, pick a language and grade level, and the tool generates a two-minute lesson you can pause, rewind, and keep asking questions about.
About Videotutor
What Is Videotutor
Videotutor is an AI-powered learning tool from a Stanford undergraduate team that generates short, personal tutoring videos on demand. Instead of handing you a wall of text, it produces the kind of clip you'd get from a patient tutor at a whiteboard: a coordinate axis drawing itself, a curve appearing step by step, a voice walking you through each move. That visual approach suits math and the sciences, where a static answer rarely explains the reasoning behind it.
The tool covers K-12 math, science, and STEM topics, plus SAT and AP math prep and language learning. You can adjust the depth by grade level, so a photosynthesis explanation for a third grader sounds nothing like the version for a senior. It generates videos in multiple languages, which makes it useful for students studying outside their first language.
A few limits are worth knowing up front. The videos run only one to two minutes, so they work best as a starting point rather than a full substitute for a textbook. It's a web tool. No dedicated mobile app. And after your free video, most of the experience sits behind a paywall.
Getting Started
- Go to videotutor.io and create an account with your email.
- Type a question, or upload a screenshot of a problem from a textbook or exam paper.
- Choose the output language and the grade level you want the explanation pitched at.
- Hit create and wait a couple of minutes while the video renders.
- Watch it, then use the built-in chat to ask follow-up questions or take the three practice questions it generates.

Best for
The users, tasks, and scenarios where this tool fits best.
Users
- K-12 students stuck on a specific problem who need the reasoning shown, not just the final answer.
- SAT and AP math test takers who want a fast visual walkthrough of a tricky question during study sessions.
- Parents who can't explain a homework problem themselves and want something their kid will actually watch.
- Teachers looking for a quick animated clip to introduce a concept in class.
Tasks
- Turning a messy geometry diagram into a step-by-step visual explanation you can rewatch.
- Getting the same concept explained at a simpler grade level when the textbook version goes over your head.
- Checking your understanding with the practice questions that come attached to each generated video.
- Studying a topic in a second language with the narration in that language.
Scenarios
- The night before a test when you hit a problem type you never really understood.
- A study session where you'd normally give up and scroll instead.
- Prep for SAT or AP math practice sets where a static answer key leaves you guessing at the steps.
- Independent language learning, where a narrated video beats reading a definition.
Key features
Question to Video in a Couple of Minutes
You feed Videotutor either text or a photo of a problem, and it returns a short AI tutoring video. The average render takes roughly two minutes. That's fast enough to sit through without losing focus. The video shows the work happening rather than just stating the result, so you can see where each step comes from. No guessing at the method.
Generate Video from Image Input
Uploading a picture matters more than it sounds. Most homework arrives as a printed problem or a diagram you can't easily retype, especially geometry with labeled figures. Videotutor reads the image, including geometric shapes, and builds the explanation around it. That's how you generate video from image instead of retyping every symbol by hand. It beats tools that only accept typed questions. Big time-saver.
Animated Math and Science Visuals
The math animation engine draws graphs, function curves, and geometric figures as the narration moves along. For abstract topics like calculus or physics, watching a curve take shape on a live axis does more than a paragraph of prose ever will. This is the core of what separates it from a chatbot that just types an answer. Big difference.
Follow-up Chat and Practice Questions
After the video, you can ask more questions and the tool responds in context. It also generates three practice questions tied to the topic, a small touch that nudges you from passive watching toward actually testing yourself. It's not a full quiz system. Still, it closes the loop on a study session.
Grade-Level and Language Adjustments
Videotutor lets you set the grade level, and it changes the vocabulary and narration style to match. A young learner gets simpler wording and a lighter voice; an older student gets more academic language. It generates across multiple languages too, so the same question can be studied in your native tongue.
API Access for Institutions
Schools and learning platforms can request API access to build Videotutor's video generation into their own products. According to the company, it has received interest from over a thousand educational institutions. Access isn't instant. You have to apply through a form and wait for approval.
Pros and cons
Pros
- Turns a stubborn problem into a visual explanation in about two minutes, which is quicker than hunting for a matching YouTube tutorial.
- Accepts photo input, so you can work directly from a textbook page or exam paper.
- Adjusts depth by grade level, letting the same concept serve very different age groups.
- Follow-up chat keeps the explanation interactive instead of ending when the video stops.
Cons
- Videos are short, one to two minutes, so complex topics get a sketch rather than a deep treatment.
- After the single free video, most usage requires paying per video, which adds up for regular study.
- No mobile app, so you're tied to a browser for content that's clearly made for short bursts of viewing.
Frequently asked questions
It takes a math or STEM question, whether typed or uploaded as an image, and generates a short animated video that explains the problem step by step with voice-over. Think of it as a personal tutor that answers with a mini-lesson instead of a paragraph.
