SnapKey is an After Effects tool built around capturing, blending and reusing animation states. It saves complex setups spread across multiple layers as a single Snap, which you can recall or blend between at any time. The stated aim is to keep those states fast and editable, so poses and variations stay adjustable after you save them.
The workflow covers switching poses, testing variations and building motion systems. Rather than rebuilding an arrangement each time, you capture it once as a Snap and bring it back or transition between saved states as needed. Version 1.6.1 covers capture, advanced blending and key animation.
SnapKey is compatible with After Effects 2026 and 2025, and the current release is dated March 29, 2026, marking its initial appearance on aescripts. A demo video is available for a closer look. It sits in the aescripts library as a way to manage and reuse animation states across a composition's layers.
