Real keyframes
What Prism leaves in your timeline: native, editable keyframes and layers you can grab and retime — not an expression stand-in or a script printout to paste.
When an AI helps you animate, the question that matters is what it leaves behind. Some tools hand you an expression that computes motion at runtime, or a block of After Effects' old scripting language to paste into a script panel and hope it runs. Prism does neither. It writes the same objects you would have made by hand: real layers, real keyframes, sitting in your timeline, ready to grab and retime.
Why this matters
A keyframe is an editable fact. You can drag it, ease it, copy it to another layer, or delete it. An expression is a recipe that recomputes on every frame — useful when you want it, but a poor substitute for animation you intend to refine. If an AI gives you motion as an expression you didn't ask for, you can't grab a single keyframe and nudge it; you have to edit code instead. (For when an expression is the right call, see keyframes vs. expressions.)
Because the AI reads the true state of your live composition before it plans — the read, reason, write loop — it writes each change as editable objects against what is actually there.
Prompt-and-paste vs. Prism
The difference shows up the moment you want to change something.
| Prompt-and-paste | Prism | |
|---|---|---|
| What you receive | A script or expression to copy | Layers and keyframes in your timeline |
| Where it runs | You paste and run it yourself | The panel executes it for you |
| Editing the result | Edit the code | Grab the keyframe and retime |
| Undo | Whatever the script did, however it did it | One step; restore point before destructive work |
| Failure mode | Cryptic script error in AE | A returned result you can re-ask against |
Prism's job is finished when the timeline holds editable work — not when it prints instructions for you to carry out.
What actually lands
Across its tool categories — animation, layers, properties and transform, timeline, effects and presets, and the rest — Prism creates and modifies the genuine AE objects behind each one. The JSON pipeline goes further: it imports a whole structure back as real layers, not a flattened render. Translators that turn an SVG into shapes, or a web-style motion description into keyframes, still resolve to native After Effects: real text and shapes, real keyframes.
This is the point of an AI-native tool rather than an AI-adjacent one. You stay in After Effects, working with objects you understand, and the AI does the building — not the lecturing.
