Use an AI agent inside After Effects
Most "AI for After Effects" writes you a script. You paste it, it throws an error on line 40, and you are now debugging ExtendScript instead of animating. An agent connected through Prism does not hand you code — it reads the open composition, acts in it, and shows you frames of what it did.
The loop
| Step | What happens |
|---|---|
| Read | The agent asks Prism what is in your project. It gets real structure, not a guess |
| Reason | It plans against what is actually there — your comp names, your layers, your frame rate |
| Write | Prism executes inside After Effects, as one undo step |
| See | Frames come back inline, so the agent checks its own work instead of assuming |
That last step is the one that changes the quality of the output. An agent that can see the frame it just rendered catches its own mistakes.
What that makes possible
| Multi-step jobs | "Build the scene, then retime it to this beat, then version it for vertical" — one conversation |
| Work against your project | It reads your layer names and comp structure rather than assuming a template |
| Self-correction | It renders, looks, and fixes without being told what went wrong |
| Your own library | Register your TypeScript helpers once and every later call can use them |
What it is not
It is not a renderer and it is not a plugin that makes footage. It drives After Effects — the same actions you would take, taken faster and without you typing them.
Try it
- "Look at my current composition and tell me what is wrong with the timing."
- "Build a lower third matching the style of the one already in this comp."
- "Retime every layer in this comp to land on the beats of the audio."

Every format
One comp becomes 16:9, 1:1, 9:16 and 4:5 with the layout rebuilt for each frame, not squashed into it. Text re-wraps, spacing re-flows, keyframes survive.
SVG with live text
Bring an SVG into After Effects as real text and shape layers. The text stays typeable and restyleable instead of arriving as outlines you cannot edit.
