Overview
After Effects has a graph editor, and everybody who animates in it has spent hours fighting the thing. Handles jump when you select a different property, the value graph and the speed graph disagree about what you are looking at, and matching the easing on twelve layers means doing the same fiddly drag twelve times. Flow is a small panel that sidesteps all of that. You get one curve, you shape it, you press apply, and every selected keyframe pair takes that curve.
It is the sort of tool that pays for itself in the first afternoon. Motion designers use it for the boring truth of the job, which is that most animation is the same handful of eases repeated consistently across a project. Flow lets you save those eases as named presets, keep them in a library, and share the library with everyone else on the job so that the whole piece moves with one voice. This build is posted with the licensing handled, so the panel installs and runs without a key.
How it changes an easing pass
Select any two or more keyframes on any property, on any number of layers, and the panel shows a single editable curve. Drag the handles, watch the curve, press apply. Every selected pair gets the same shape, regardless of whether they are position, scale, rotation, opacity or an effect slider, and regardless of whether the values are spatial or temporal.
That uniformity is the point. A title sequence where every element uses the same custom ease reads as designed, and one where each element was hand dragged reads as sloppy in a way that is hard to name but easy to see. Flow makes the consistent option the fast option, which is the only way it actually happens under a deadline.
The preset library
Presets are saved with a name and a thumbnail of the curve, and the library is a plain file you can copy to another machine or drop in a project folder. The bundled set covers the standard easing vocabulary, the quads, cubics, quints, backs, elastics and bounces, and there is nothing stopping you replacing all of them with a house set.
For teams, the shared library is the feature. Put the file on the network, point everyone at it, and the ease named in the brief is the same ease in every artist's project. Presets can be applied by keyboard shortcut as well, so the common two or three become muscle memory.
Fitting it into a project
Flow works on keyframes, not on expressions, and it leaves the keyframes as ordinary After Effects keyframes afterwards. That means a project handed to someone who does not have the panel installed still opens and plays correctly, which is not true of tools that leave an expression behind. Nothing about the render depends on the plug-in being present.
It also respects the difference between value and speed. The curve you shape is the eased motion, so a curve that looks right in the panel behaves right on the layer. Roving keyframes and hold keyframes are left alone rather than silently converted, and undo works normally, which sounds like a low bar until you have used a panel where it does not.

Questions about this release
Does the project need Flow installed to render?
No. It writes ordinary keyframes and then gets out of the way, so any machine can open and render the project.
Which After Effects versions does it work with?
The recent releases including the current 2026 cycle. Very old versions lack the panel API it uses.
Why does the panel not appear in the Window menu?
Scripts are usually blocked from writing files until you enable that option in preferences, and the panel needs it. Enable it and restart After Effects.
Can I use my own preset set?
Yes. Replace or add to the library file. It is plain and portable between machines.
Comments
Shared the library folder with the rest of the team and the whole spot suddenly moves like one piece.
Installed into the 2026 build fine. Had to turn on the script write setting first.
Comments are read before they appear. If a build stops working, say so here and it gets rebuilt rather than quietly left up.
Twelve layers, one ease, one click. I am never opening the graph editor again if I can help it.
