Easify 3, developed by Leyero, is an animation easing extension for After Effects and Premiere Pro. It is described as the first animation easing extension for Premiere Pro, bringing an animation graph editor to that application. It ranks 24 in the aescripts library.
The extension provides an animation graph editor with Bézier and mathematical curves, plus special curves customization. You can create, import and export preset libraries, save unlimited presets, and store copied easing as presets. Curve tools include mirror animation curve, time-reverse keyframes and rove across time.
In After Effects, Easify 3 applies Bézier easing directly to keyframes, copies and pastes easing, and moves keyframes to the playhead. It also offers a flexible UI and Spell Book integration for keyboard shortcuts. The pro version adds combining Bézier curves with math curves for advanced curve combination. Version 3.0.16 was released on June 3, 2026, and a demo video is available.
