Who it is forA non-specialist or product person who has a coding agent open and wants a 3D explainer without writing Python by hand.

The problemLearning a new animation library and its setup before making a single clip is a barrier.

The outcomeThe agent installs ManimGX, writes the scene, renders it and opens the resulting video.

What you need first

  • Python 3.13 or newer for the pip install route
  • Node.js and npm for the browser route (npm install manimgx)
  • A browser with WebGPU support to view scenes in the web page
  • An AI coding agent such as Claude Code, Codex or Cursor, only for the prompt-driven route

Steps

  1. Open Claude Code, Codex or Cursor.
  2. Paste this prompt, replacing the topic: Follow https://manimgx.academa.ai/llms.txt. Install ManimGX, make a 3D animation of <topic>, and open it.
  3. Watch the rendered video the agent opens.
  4. Ask the agent to change the camera, colors or timing, and render again.

Prompt for your agent

Follow https://manimgx.academa.ai/llms.txt, install ManimGX, and make a 3D animation of <topic>. Expected output: a rendered MP4 that you open for the user. Verify that the video shows the <topic> scene from start to end.

Caveat. The README only gives the prompt and the llms.txt link, so the agent's setup steps depend on the instructions in that file and on the agent's own environment.
