iExpressions allow you to use After Effects expressions without writing or reading a single line of code. It contains over 85 iExpressions – and each of them comes with an easy and intuitive to use interface.

Loops any layers, footage or comps with one click™

When you bake keyframes you get a keyframe for every frame, this script cleans that up and only sets keyframes where there are needed. Sweet!

Create an instance of an effect with one click. Behind the scenes the script makes a copy of the effect and links it with expressions in a way that allows the instance to be anywhere including a different comp.

Converts the expressions in your projects so that they are compatible with After Effects running in any language.

Apply several expressions to a property such that each expression is active only for a certain period of time. Instead of an abrupt change between the expressions you can also smoothly transition from one expression to the next. Furthermore, you can specify time intervals in which no expression is active such that the keyframed motion is considered.

Automatically fade, scale and rotate layers in and out

Search, apply and edit expressions throughout your project. Expressions can be saved, or instantly applied to one or more properties. It can also check for broken expressions, re-enabling them automatically where possible.

Search for effects used in your After Effects project. Find where specific effects have been used, turn them on or off, delete then, or link them together to create cloned effect instances.

Get three awesome scripts for the price of two. pt_EffectSearch, pt_ExpressEdit & pt_TextEdit

Make a copy of a layer and link all its properties to the original using expressions.

This script can be used to automatically add wiggle, smooth and loop expressions to any selected properties.

Duplicates the selected layers and if any of the layers have expressions referencing any of the layers being duplicated it will update the expressions to point to the newly duplicated layers. Might make more sense if you watch the demo

Ease and Wizz is a set of expressions for After Effects that give you more ways to interpolate between values. The obvious use is in motion, but they can be used on animated properties of any kind. They’re applied with an After Effects-ish palette that can be docked, so it’s very easy to use.

Allows you to animate a mask shape using expressions.

Activates disabled expressions in selected layers or entire comp. A true life saver!

Locks selected properties by adding an expression with the current value.

Translates expression control names according to the language of the running version.

Version 1.5 now supports After Effects CS5!

A centralized location for you to store all your expressions. When you apply an expression from the toolbox, it will rename and/or create any necessary controllers so the expression works properly.
