Text-to-Manim: AI tools that generate math animation code (2026)

Text-to-Manim is a small but growing category of AI tools. Type a prompt like "show the Pythagorean theorem with a square on each side of a right triangle, then morph the two smaller squares into the larger one." Get back a video. Ideally a clean, vector-quality math animation that looks like the kind 3Blue1Brown popularized through his educational channel.

This post covers what these tools actually do in 2026, what they handle well, where they break, and when raw Manim is the better choice. No marketing fluff. The goal is to help you decide whether to use one for your next video.

What "text to Manim" means

Manim is a Python animation library originally written by Grant Sanderson and now maintained by the Manim Community as a separate fork (3b1b/manim is the original; ManimCommunity/manim is the maintained community edition). It produces vector-style mathematical animations: smooth curves, LaTeX equations that morph, graphs that zoom and rotate, geometric proofs that unfold step by step.

"Text to Manim" describes any tool that converts a natural language description into Manim Python code, then renders that code into video. The user never sees the Python unless they want to. Three things happen under the hood:

1. A large language model reads the prompt and produces Manim code.
2. A sandboxed environment runs that code through Manim Community Edition.
3. The resulting MP4 lands in the user's hands.

Step two is where most failures happen. Manim has a small but pointy API. Mixing up Tex (raw LaTeX, brittle) with MathTex (math mode) is a common LLM mistake. Forgetting to call self.add() versus self.play() is another. Tools that survive in this space have to handle these errors gracefully.

Why anyone wants this

The honest answer: writing Manim code is hard. You need Python, basic linear algebra, and patience for a steep API. The official Manim docs are good, but going from "I want to show a Fourier series" to a polished video takes hours for a beginner. Maybe a full day for a four-minute video.

Educators, students, and content creators want the output without the climb. They have ideas. They want a video tomorrow, not next week. Text-to-Manim tools compress the gap. The cost is some loss of control: the AI picks colors, timing, and camera moves you might not have chosen.

The current landscape

As of May 2026, three approaches dominate.

1. Hand-rolled GPT prompts

Anyone with a ChatGPT or Claude account can ask for Manim code. The model returns Python, you copy it into a local environment, run manim -pql scene.py, and hope it works. This is free and flexible. It also requires you to install Manim, fight with LaTeX dependencies, and debug rendering errors yourself.

The output quality varies. GPT-4 and Claude 3.5 are reasonable at simple scenes (one equation, one graph). They are unreliable for complex multi-scene videos. Expect to iterate three to five times on harder prompts.

2. manimGPT and similar proofs of concept

Several open-source projects (manimGPT being the best-known in 2024) wrapped GPT calls around a Manim execution loop. Most are unmaintained. A few hobbyists run them on Hugging Face Spaces or local Docker. They work, sometimes. Quality and uptime vary.

3. Hosted text-to-Manim products

Madio (madio.live) is one. The pitch is simple: paste a prompt, get a video, no install. Under the hood we use Google Gemini 3 Flash for fast iterations and Pro Thinking for harder prompts, render in a sandboxed Manim Community v0.18.1 environment, and return an MP4 plus optional .py source. The Free tier gives 5 credits, 30 seconds at 720p, watermarked. Paid plans go up to 4K and API access.

Other hosted offerings exist with different LLM backends and feature sets. The category is small enough that the right tool depends on your specific use case.

What hosted tools add over raw prompts

If you have GPT or Claude, why pay for a hosted tool? Three things matter.

Sandboxed execution. Generated code sometimes does unsafe things: long renders that hang, infinite loops, requests to external APIs. Hosted tools run in throwaway containers with timeouts, so you do not have to install Manim, manage LaTeX, or kill stuck processes.

Retry loop on syntax errors. When the LLM produces broken code, Madio catches the error message, feeds it back into the model with the original prompt, and tries again. Most failures are fixable in one or two retries. Hand-rolled GPT requires you to do this manually.

Downloadable artifacts. On the Starter plan and above, you get the .py source alongside the MP4. You can take that file, run it locally, edit timings or colors, and re-render. This is the bridge between "AI did it" and "I refined it." On the Team plan you also get an FCPXML export for Final Cut Pro round-tripping.

For experimentation, hand-rolled is fine. For consistent output across multiple videos, hosted saves time.

Honest limits

Anyone selling you a text-to-Manim tool that "just works" is overselling. Real limits:

• LaTeX errors. LLMs misuse Tex versus MathTex constantly. We patch this in our prompt augmentation, but it still happens on edge cases. If your equation contains unusual symbols (Hebrew letters, custom packages), expect failures.
• Over-rendering. A prompt like "explain calculus" is too broad. The model tries to fit a textbook into 30 seconds. Single-concept prompts work better than survey prompts.
• Color and layout drift. Without a style guide, the AI picks colors that may clash. Hosted tools mitigate this with default palettes, but you are not getting pixel-perfect consistency across a series.
• 3D scenes. Manim's 3D module is harder for LLMs to reason about. Camera moves and rotations break frequently. Stick to 2D unless you really need 3D.
• Custom mobjects. If you want a unique shape not in Manim's standard library, the AI will sometimes hallucinate API calls that do not exist.

A reasonable expectation: 70 to 80 percent first-try success on focused prompts, with a quick edit fixing most issues. Not 100 percent.

When to use AI versus raw Manim

Use AI when:

• You need speed over polish (a video tomorrow).
• The concept is well-defined and single-purpose.
• You do not know Python or do not want to install Manim.
• You are prototyping and will refine later.

Use raw Manim when:

• You need exact control over timing, color, and layout.
• The animation is part of a larger series with consistent style.
• You are comfortable with Python and want to learn the API.
• The prompt complexity exceeds what current LLMs reliably handle (custom mobjects, intricate 3D, complex synchronizations).

The hybrid path works well. Generate the first draft on Madio, download the .py, refine locally. This is faster than either extreme.

Workflow examples

For a one-off explainer video for a class:

1. Write a prompt as specific as possible. Name the equation, the variables, the visual layout.
2. Render on Madio Free or Starter.
3. If the result is close, accept it. If not, refine the prompt and retry.

For a YouTube series with consistent style:

1. Use Madio to draft each scene.
2. Download the .py files on Starter or Pro.
3. Refactor a shared style file (colors, fonts, fade timings).
4. Re-render locally with Manim CE for consistent output.

For a one-shot social clip:

1. Madio Free, 30 seconds, accept the watermark.
2. Post.

Pricing snapshot

Madio's tiers as of May 2026:

Compare this to running Manim yourself: free in cash, but you pay in setup time (1 to 3 hours for a clean install on macOS or Linux, longer on Windows) and learning curve.

Try a few prompts

Browse the gallery to see what current text-to-Manim output looks like across different concepts. Or jump straight into /create and try a prompt of your own. Five free credits is enough to test whether the category fits your workflow.

If you want pre-built starting points, check /templates for prompts grouped by topic (calculus, linear algebra, geometry, statistics).

Final note

Text-to-Manim is not a finished product category. The tools work well for a narrow band of prompts and break on the edges. If you treat them as a draft generator that needs human review, they save a lot of time. If you expect a one-click solution, you will be frustrated.

Pricing is reasonable: a few dollars per usable video on the paid tiers, free for prototyping. The technology will get better. Right now, in 2026, it is good enough to be useful.
