Dozens of features, no gimmicks

Animation in After Effects is all about keyframes and layers, and handling them manually is tedious. Keystone has been carefully designed to tackle all the most common challenges in the After Effects timeline and save you countless hours!

NEW in v3.1 – Anchor section

You can finally move anchor points and create null layers (💡 CTRL/CMD + click) directly from Keystone! This classic feature comes with multiple options to target individual layers, layer groups, the composition, and even precise coordinates! You can even manipulate the internal anchor points of shape layers and text layers.

What's new in Keystone 3?

Already familiar with Keystone?
Here's a summary of what's new in this major release.

Keyframe Values

Add, multiply, round… Works on all selected keyframes.

Layer Order

Keep your layers organized with a wide range of sorting methods.

Section shortcuts

Toggle sections on and off only when you need them.
💡 CTRL/⌘ + click to close them all

New Stagger options

A Bezier controller to bring life to your staggers, along with three options for even easier use.
💡 ALT + click to activate the cumulative mode

New in Keystone 3 - Revamped Stagger features

Simple. Clear. Customizable.

Keystone's interface is built for speed and simplicity, with most actions just one click away. The new section shortcuts let you show or hide sections instantly, so you can keep your screen uncluttered and focused on your work.

Save a LOT of time

Manipulating keyframes and layers takes a lot of time when done natively in After Effects. By using Keystone just a few times a day, you will easily save several minutes per day, an hour per week, and several hours per month.
The more keyframes and layers you use, the more time Keystone saves you!

Complete overhaul of the Stagger and Distribute functions

Staggering is one of the most widely used techniques in motion design.
With the new Bezier controllers of Keystone 3, say goodbye to boring linear staggers and distributions and take your animations to the next level. On top of that, 3 new modes make it more intuitive than ever.

Other tools can't. Keystone can.

After Effects is notoriously known for breaking easings when you move keyframes, and other third-party tools on the market don't do any better.
Keystone is the only tool that performs the necessary calculations to preserve your carefully crafted motion curves.

Align your tangents and keep them aligned effortlessly

A user favorite since Keystone 1, the "Constant Speed" feature takes away the struggle of aligning tangents by hand. Best of all, these constant speeds are preserved when using any other Keystone 3 function.

Link / unlink keyframes and layers

The "Link" options are arguably the most underrated feature of Keystone 3! They unlock a whole new level of keyframe and layer manipulation, enabling you to link or unlink them in ways that are impossible natively in After Effects.

Up to 3 modes per function

Easily accessible with shared hotkeys, modes let you control how keyframes or layers are grouped together.

default
Layer mode

Each layer's keyframes move independently.

ALT + click
Property mode

Keyframes are grouped by property across layers.

SHIFT + click
Global mode

All selected keyframes move as one.

There are a LOT of tools you could use to make animating in After Effects easier – my favorite panel just got a major new update that makes things even easier:

Picked it up last week. It’s been a big help already. Made the cut to be permanently docked.

New version of Keystone just dropped! It's already one of my most-used perma-docked tools for #AfterEffects, and now you can connect keyframes to the in/outPoints of layers?! Can't wait to try it out @RomainCousin https://t.co/oX6CPMQT2b

I just bought it now and I can say a GAME CHANGER in terms of speed and workflow. Thank you @RomainCousin
