After Effects is a great tool that enables me quickly visualize and test robust animation patterns throughout web design and games, share those with the development team and clients, and even test variants with users to get quick validation on a design before it goes into production.
After Effects is a powerful tool for creating high-fidelity prototypes that visually represent how a product or design will look and function.
After Effects provides a wide range of animation tools and features that allow you to create complex interactions and transitions between screens and elements.
Creating a prototype on After Effects can save a significant amount of time as compared to coding a functional prototype from scratch.
After Effects makes it easy to iterate on design concepts and make changes to the prototype quickly, enabling a more flexible and agile design process.
