Generate an endless variety of complex shape layer animations in seconds. Works with text & vectors too!

ShapeMonkey is a fast and intuitive way to automatically create shape-based animations in After Effects.
If you have experience creating dynamic graphic animations with shape layers, you know that it’s a powerful feature. However, it can take a while to understand how everything works. It can also become difficult to navigate – each shape layer may have multiple transform controls, each buried in its own sub-category.
ShapeMonkey is built to make working with shape layers much simpler. Designed for easy experimentation and quick iterations, there are no limits to the animations you can create.
