Aescripts - Keystone 3 - 1.00.01 (Win, Mac)

Keystone 3 from Aescripts is a professional-grade After Effects toolbox created for animators who demand fast, intuitive, and highly accurate control over their keyframes and layers. Designed to eliminate tedious timeline management, this upgraded version uses intelligent automation to streamline complex animation tasks such as staggering, alignment, ordering, linking, and preserving easings—ensuring smooth, consistent motion curves throughout your workflow.

With major enhancements in performance and usability, Keystone 3 introduces a wide range of powerful features. The new Keyframe Value Operations allow you to add, multiply, round, and perform mathematical adjustments across multiple keyframes and layers at once, offering unmatched precision. The updated Layer Order tools make it easy to sort and organize extensive compositions, helping keep even the most complex AE projects clean and manageable.

One of the standout upgrades is the fully redesigned advanced staggering system. Featuring Bezier-based stagger controls, animators can now achieve smooth, organic staggering patterns with ease. Keystone 3 adds three new calculation modes, including a Cumulative Stagger mode accessed via ALT + Click, offering more intuitive and flexible layer distribution without risking broken easings—a common issue in native AE workflows.

Keystone’s signature functionality continues to shine with constant-speed tangent alignment, allowing you to reposition tangents while maintaining consistent speed throughout the animation. The tool also delivers unique linking and unlinking options for both keyframes and layers, enabling synced animations and versatile multi-mode functions that expand creative control. Most tools offer up to three modes, accessible through shared hotkeys for ultra-efficient workflow transitions.

Its interface has been rebuilt for speed and clarity, giving animators a clean, customizable workspace that adapts to their needs rather than cluttering the screen. With section shortcuts for collapsing UI groups and intuitive navigation, Keystone 3 focuses entirely on helping animators stay immersed in creative work instead of UI management.

Above all, Keystone 3 is trusted by thousands of professional animators who rely on it daily to elevate their After Effects workflow. By maintaining easing integrity, automating repetitive tasks, and delivering an advanced yet streamlined UI, Keystone 3 remains one of the most essential tools for modern motion graphics artists seeking better speed, control, and animation quality.
