Get a 3Blue1Brown-style explainer video.

An open-source pipeline of agents researches your topic, writes the storyboard, animates it in Manim, watches its own frames, revises them, and narrates the result. Unsupervised, end to end.

Generated fully automatically from a topic prompt and two methodology documents — storyboard, animation code, QA, and narration included.

How it works

1 · Research. An agent builds a brief: the core tension, the step-by-step logic, real numbers, common misconceptions.
2 · Direct. A director turns the brief into scenes with narration beats and a precise visual plan.
3 · Animate. An animator writes Manim code — the same engine 3Blue1Brown built — timed to the narration.
4 · Critique. A vision critic inspects rendered frames for overlaps, cutoffs, wrong math, and dead time, then sends fixes back. Then everything gets narrated and assembled.
