Common questions
Can I use Math Visualizer in my classroom / textbook / course?
Yes. All tools are free for educational use. Our guides and examples are CC BY 4.0 — copy, adapt, share with attribution. No permission needed.
I want to embed a tool on my commercial site. Do I need a license?
Yes — it's free, but we ask you to request a license so we know who's embedding at scale. Include your domain and estimated monthly views. We'll reply with a simple agreement.
I found a bug. What should I include in the report?
Browser/OS, the tool URL, steps to reproduce, expected vs actual behavior, and a screenshot if relevant. The more detail, the faster we can fix it.
Can you add [specific math topic] as a new tool?
Maybe! Submit a feature request via the form. We prioritize based on how many people ask, how well it fits the "interactive model" format, and whether we can build it cleanly.
Are the tools open source?
The rendering engine and tool code are not open source. The educational content (guides, examples, blog posts) is CC BY 4.0.
Do you offer custom development or white-labeling?
Not currently. We're a small team focused on the core tools. For custom work, email us and we'll point you toward freelancers who know our stack.
