Introducing Mathify.dev — AI-Generated Math Animations

I’ve been working on something new, and I’m finally ready to show it: Mathify.dev, an AI tool that creates Manim-style mathematical animations from plain-language prompts.

Manim is powerful, but writing the code for even simple scenes can take hours. My goal with Mathify is to make the process dramatically faster: describe what you want, and Mathify writes the code, renders it, and gives you the animation.

Let me show you what it looks like in practice.

A Simple Example: A 2D Sine Wave

I started with something easy:

❝

“Render a quick 2D animation of a sine function.”

— Me

A few seconds later, Mathify generates the code, runs the render, and produces the animation. That’s the basic idea — fast, natural-language-driven mathematical visuals.

Sine Wave Animation

The animation shows a smooth 2D plot of the sine function, with a yellow dot moving along the curve as it traces the wave pattern from left to right across the range of -6 to 6 on the x-axis.

Testing a Bigger Example: Neural Networks

Back in 2024, I built a full animation explaining the concept of a neural network.
It took days to write the code and tune the visuals manually.

So I asked Mathify:

❝

“Render a quick explanation of the concept of a neural network.”

— Me again

In about a minute, Mathify produced a complete animation with code included.
Is it perfect? Not yet. But it’s a massive head start: you get editable Manim code you can refine, instead of starting from nothing.

Neural Network Overview

The animation visually explains how a neural network works by showing the layers and connections, highlighting a forward pass through the network, and illustrating the equation \( y = \sigma(Wx + b) \) using LaTeX. It also includes a brief overview of the training process at the end.

That’s where I see the value — speeding up exploration and teaching.

Another Test: The Fibonacci Sequence

For the last free render in this demo, I tried:

❝

“Render a quick animation of the Fibonacci sequence.”

— Me enjoying some math

Mathify began by displaying the number sequence (it even made a small mistake — easy to fix in the generated code). Then it produced a graphical representation, including the classic spiral associated with the sequence.

Fibonacci Sequence Animation

The animation visually demonstrates how the Fibonacci sequence is created by stacking boxes that represent each term, showing how each new term is formed by adding the two previous ones, and it concludes with the simple formula that defines this relationship.

These tests show the potential: quick mathematical animations, ready to refine or use as is.

What’s Next for Mathify

This is the first version, and there’s a lot I want to improve:

The ability to keep chatting while animations render
Instant visual previews
More robust code generation
Faster backend rendering
Smoother workflow in the UI
Better handling of advanced Manim scenes

There’s a long list of features I’m excited to build. I’ll be coding like crazy in the coming weeks.

Try It Out

Mathify.dev is live today.
You can try it, break it, test different prompts, and send feedback. Every comment helps.

I’m excited to see what you create.
