Manim

Manim is a Python animation engine for explanatory math videos. Users write scenes in code, describing objects such as LaTeX text, shapes, graphs and number planes, and the animations applied to them, and Manim renders the result to video. The Community Edition (ManimCE) is a fork of 3b1b/manim, the tool originally created by Grant Sanderson for the 3Blue1Brown videos, and is maintained by a community of contributors.

It supports LaTeX and MathTex rendering, transforms, function plots, vector fields and stream lines, boolean shape operations, and non-linear transformations of grids. Scenes are rendered from a command-line tool (for example manim -p -ql example.py SquareToCircle), and a %%manim IPython magic allows use in Jupyter notebooks. A Docker image and an online Jupyter environment are also provided.

Manim is free and released under the MIT license. It is a code library rather than a hosted service, so it is installed locally (documentation covers installation per operating system, and developers commonly use uv). According to the README, the project is undergoing a major refactor, and new feature contributions are generally not being accepted for now. YouTube creators have shown AI coding agents, including a Hermes skill and GPT models, using Manim to generate explanatory animations from prompts.
