3 free preview videos
Every account with a verified email renders 3 videos free (720p, watermarked) and can export any of them in HD later.
Free math video creator
Create animated math videos — free to start
Sign up and start from a template: say what you want to explain, CurvG fills in the parameters and renders it in the cloud. Your first 3 videos are free previews (720p, watermarked); clean 1080p versions use credits, charged only when a render succeeds.
What free actually includes
No trial timer. The free tier is a working workflow, not a demo.
Planning & review
Describe the idea, get a scene plan, and revise it — planning never charges credits.
Manim code export
View, copy, and download the generated Manim Community code, free.
The same model as paid plans
Free and paid plans run the same generation pipeline with no downgraded model; paying buys more videos.
From idea to video in three steps
01
Describe the math
State the teaching goal and the formulas or objects that matter — or start from a curve in the encyclopedia.
02
Review before rendering
Check the proposed scene plan and Manim code. Fix the explanation while it's still cheap to change.
03
Render and download
Spend credits on a cloud render only when the plan is right. Download the MP4 and keep the code.
Where credits go — and where they don't
The billing rules are deliberately simple:
Planning is always free
Describing, revising, and approving scenes never consumes credits.
Renders cost credits
A standard render currently costs 20 credits, charged only when it succeeds.
Failures are refunded
Failed or canceled renders return their credits automatically.
Free-tier questions
Is it really free to make a math video?
Yes: your first 3 videos are free previews (720p, watermarked), and Manim code export is always free. After that, Starter and Pro add monthly HD render credits.
What exactly costs credits?
Only cloud renders. A standard render currently costs 20 credits; failed or canceled renders are refunded automatically.
What happens after my free video?
Nothing breaks: you can keep planning scenes and exporting Manim code for free, and subscribe to Starter or Pro when you want more videos.
