Manim Math Animation · Video Mode

AI math animation generator: animated derivations from your own notes

Upload a PDF, lecture notes, or a problem set and Scholarly builds a narrated video that animates the working — secant lines tightening into tangents, rectangles converging on an integral, vector fields flowing — rendered with Manim, the engine behind 3Blue1Brown-style animation.

Scene plan · Calculus I, Week 4
  1. 1

    Scene 1 · Secant to tangent

    The derivative as a limiting slope

    A secant line on f(x) = 0.3x² tightens onto the tangent as Δx shrinks toward zero.

  2. 2

    Scene 2 · Riemann sum

    The definite integral as accumulated area

    Rectangles under the curve multiply and converge on the exact area between a and b.

  3. 3

    Scene 3 · Vector field

    Rotation in the plane

    The field (−y, x) is drawn with flow particles so the circular motion is visible, not just written.

How it works

From source to animated derivation in three steps

Pick the Manim Math Animation mode in the video lecture creator. Everything else is the same upload-and-generate flow.

  1. 01

    Add your math source

    Upload up to 3 PDFs — a textbook chapter, lecture notes, a problem set, or a physics handout — or pick files already in your library.

  2. 02

    The AI plans vetted scenes

    Scholarly reads the source, finds the concepts that can be animated, and matches each one to a tested Manim scene: derivatives, integrals, function transforms, equation derivations, vector fields, or the Pythagorean theorem.

  3. 03

    Watch the working unfold

    In about 10 to 25 minutes you get a narrated, chaptered video with a searchable transcript, captions, question checkpoints, AI chat, and one-click flashcards.

What you get

Precise animation, grounded in your material

Every scene is built from the concepts in your source, so the video teaches what your course actually covers.

Built with Manim

Scenes are rendered with Manim, the open-source animation engine created by Grant Sanderson for 3Blue1Brown. Scholarly is not affiliated with 3Blue1Brown; it uses the same engine to draw the math precisely.

Six vetted scene types

Derivatives (secant to tangent), integrals (Riemann sums), function transforms, step-by-step equation derivations, 2D vector fields, and the Pythagorean area proof — each a tested recipe, not improvised code.

Never fails on an unmatched topic

When a concept needs a visual the vetted scenes do not cover, the same request continues through a flexible math renderer instead of failing or splitting into a separate artifact.

Chapters, transcript, and captions

Every video ships with chapter navigation, a searchable transcript, and synced captions, so you can jump straight to the derivation you need.

Checkpoints and AI chat

Interactive question checkpoints test you as you watch, and AI chat answers follow-up questions about the video without leaving the page.

Flashcards in one click

Turn the video into flashcards instantly, or keep going with quizzes and study guides from the same source.

Why it helps

Math is easier to follow when the working moves

Updated August 2026

Upload up to 3 PDFs or notes and choose the Manim Math Animation video mode. Scholarly matches the concepts in your source to vetted Manim scenes — derivatives, integrals, function transforms, equation derivations, vector fields, and the Pythagorean theorem — and renders a narrated, chaptered video in about 10 to 25 minutes; topics that need a different visual continue through a flexible math renderer instead of failing. The Free plan includes one lifetime AI creation at 720p with a fixed 2-minute length; paid plans add 1080p, watermark removal, MP4 download, and a target length up to 45 minutes.

A static page can show you that the derivative is the limit of a difference quotient. It cannot show the secant line sliding toward the tangent as Δx shrinks. Animation makes the limit a thing you watch happen, and that is the difference between memorizing a definition and understanding it.

This mode is deliberately strict. The planner only uses scenes that are known to render correctly, and it refuses to force a history essay or a verbal definition into fake algebra. If your source does not contain a plottable relationship, the video says so rather than inventing one. When the topic is real mathematics that the vetted scenes do not cover, the flexible math renderer takes over inside the same request.

Because the scenes are grounded in your own notes, the notation, the example functions, and the order of steps match what your course uses. Pair the video with the built-in flashcards or a quiz to move from watching the derivation to reproducing it yourself — which is what the exam asks for.

For work and teams

Engineering, finance, and data teams onboard people onto formulas all the time — discount rates, signal transforms, gradient descent, load calculations. An animated derivation explains the reasoning once, clearly, and can be rewatched by every new hire. Pair this mode with the training video generator for the rest of your curriculum, or see Scholarly for Teams for shared workspaces and pooled credits.

FAQ

Common questions

What kinds of math can it animate?

The vetted scenes cover derivatives (a secant tightening into a tangent), definite integrals (Riemann sums converging on an area), function transformations, multi-step equation derivations, 2D vector fields with flow, and the Pythagorean area proof. For other mathematical visuals, the same request continues through a flexible math renderer. It is best for calculus, physics, statistics, and any STEM topic where the working matters as much as the answer.

Is this affiliated with 3Blue1Brown?

No. Manim is the open-source animation engine originally created by Grant Sanderson for his 3Blue1Brown videos. Scholarly uses that engine to render precise mathematical animations from your source; it is not affiliated with or endorsed by 3Blue1Brown.

What happens if my source has no math to animate?

The planner will not invent a scene. If your source is, for example, a history essay or a legal procedure with no plottable relationship, the Manim mode reports that it is unmatched rather than forcing it. For that kind of material, use the Standard, Illustrated, or Freestyle video mode instead.

What do I upload?

Up to 3 PDFs — textbook chapters, lecture notes, problem sets, or physics handouts — or files already in your Scholarly library. On the Free plan, a single upload is limited to 8MB or 32 PDF pages.

Is it free?

Yes to start. The Free plan includes one lifetime AI creation at 720p with a fixed 2-minute length. Premium ($30/mo or $144/yr) includes 10 AI creations per week; Laureate ($99/mo) includes 80 per week. Paid plans add 1080p, watermark removal, MP4 download, and a target length up to 45 minutes. Every video mode is available on every plan.

How long does generation take?

Usually about 10 to 25 minutes, depending on the length of the source and the number of scenes. The video lands in your library when it is ready, with chapters, transcript, captions, checkpoints, AI chat, and flashcards generated alongside it.
