ManImTired

Inspiration

3 Blue 1 Brown videos take SSOOOOO long to edit. This program automatically creates the animations and the video itself.

What it does

ManImTired takes an educational concept as a text prompt and automatically generates a full Manim animation script. It uses LLMs to plan slide content, write explanations, generate diagram descriptions, and finally output a valid, well-structured Manim scene. It includes a built-in GUI for users to input prompts, choose between different LLMs (Llama 3.1 8B hosted on Cerebras, GPT-4o, or o3-mini), and preview generated animations.

How we built it

DearPyGUI for the interactive GUI.
Manim as the animation engine.
LangChain for prompt engineering and model chaining.
Cerebras and OpenAI APIs for LLM interactions.
Pydantic + JSON parsing to ensure the output code is structured and valid.
Custom agents to break down tasks into: content planning, slide explanation, diagram generation, and script assembly.
Robust post-processing logic to fix common Manim issues and enforce visual layout constraints. ## Challenges we ran into
Prompting LLMs to generate valid Manim code was tricky—especially enforcing layout and animation constraints.
Managing LLM output structure required extensive validation and fallback logic.
Preventing broken animations (e.g., overflowing visuals, unplayable shapes) needed careful patching and safety functions.
Rendering stability—render timeouts and Manim quirks required defensive scripting and background threads. ## Accomplishments that we're proud of
Built a full pipeline from prompt → plan → script → rendered video with fallback handling.
Integrated multiple LLMs into a GUI that lets users experiment with different models.
Automated Manim animation creation with well-structured educational content and visuals.
Created robust safety nets to ensure output is both correct and visually coherent. ## What we learned
LLMs are powerful, but it is not that great with positioning
Combining AI planning with procedural animation may open the door for scalable educational content generation. ## What's next for ManImTired
Improving content and animations
Adding audio narration and subtitle generation for accessibility.
