About Phyō
What it is, why it exists, and who is building it.
What it is
Phyō is a library of interactive tools for learning math and science. You grab something on screen, move it, and watch what happens. Seeing a shape rotate in real time teaches symmetry faster than a picture in a textbook.
It is not a sandbox. Desmos and GeoGebra hand you an empty canvas and expect you to build the lesson yourself. Phyō is a curated library. Every tool is built from scratch to teach one idea, and a person decides when it is done.
The library has three kinds of tools. Lessons walk through one idea. Puzzles give you a scenario, a problem, and a set of tools to choose from. Instruments are open-ended modeling tools you drive yourself. Every one of them works in a shared session, so a tutor and a student can work on the same thing at the same time.
Who we are
We believe education is the transfer of knowledge from one generation to the next. As we enter a future filled with AI and high-technology, it's more important than ever before to ensure our youth are given access to tools which are accurate, insightful and human. Tools that allow them to build the future we all want to live in.
Phyo is not “anti-AI”. We believe AI can be a very powerful tool when used properly. That being said, we know that as adults we must take responsibility and ownership over the information we use to educate our youth. A chatbot will never replace a human educator and we don't see any reason we should want it to.
Rachel
Owner and founder. Rachel started Phyō out of a love for mathematics and teaching. She went to school to study the Greek classics, and still enjoys learning just as much now as she did then. She cares deeply about the future, and wants to build something that leaves the world a better place.
Mathieu
Technical founder. Mathieu is the one who builds the tools on this site. He has over ten years of building audio and web software behind him. He's worked on everything from XR systems to microcontrollers. What he really loves is teaching, and that's what he's excited to do here.

Send us a messageWhy Phyō exists
A few days before the project began, I was helping my sister with geometry homework. She was stuck on rotational and radial symmetry, and the static pictures in her textbook were not helping.
She lives in another state. Helping her took a Discord account, photos of her homework, a phone call, a screen share, two failed attempts to build something in Desmos and GeoGebra, a manually built interactive in Blender, and notes drawn over her homework in GIMP.
When she saw the shape rotating in real time, with a ghost of the original underneath it, she understood it. Just like that.
That is the idea behind Phyō. A growing library of interactive tools that make a single idea click. It is also the reason live sessions exist. The whole thing started as a call across two states, and a shared session now removes every step in the middle.
What makes a good tool
Every tool is built against the same four rules. If it does not meet all four, it is not finished.
Interactive
You do not just read about the concept. You reach in and change it.
Cause and effect
Every input produces an immediate, visible output. Understanding comes from trying things.
Intuitive
Built to give you a feel for the idea, not just the formula.
Visual
You can always see exactly how your input changes the result.
