Geometry animations made with AI

Proofs without words become proofs with motion: the Pythagorean theorem, angle sums, similar triangles, circle theorems and transformations, each animated from a short description.

Prompts to start from

• Prove the Pythagorean theorem by rearranging four right triangles
• Show why the angles of a triangle add up to 180 degrees
• Animate the inscribed angle theorem

Questions

What is in the Vismo Library?

Hand-reviewed, verified math and science animations organised by topic: calculus, algebra, geometry, trigonometry, linear algebra, probability, number theory, physics, chemistry and computer science. Every item passed the frame-by-frame layout check and a human review. Anyone can watch; paid members download the video and the Manim source file.

Can I use Library animations in my lessons and videos?

Yes. Paid plans include unlimited MP4 downloads for classroom use, plus Adapt: change the pace, colours, numbers or narration of any Library animation and create a version for your classroom or course. Adaptations show an estimate before you start and charge actual usage. Creators are credited on the Library page; no attribution is required inside your lesson.

How long does it take to generate an animation?

Generation time depends on the model, scene complexity, video length and narration. Vismo shows progress while it writes the scene, prepares speech and renders the video. Complex lessons can take several minutes.
