Write After Effects scripts with AI (ChatGPT, Claude)
ChatGPT, Claude or any MCP client connected to Prism can write an After Effects script from a sentence, run it inside your open project and check the result, with no .jsx file to save, paste and debug.
Search this and you land in threads where someone asked ChatGPT for a script, ran it from File, Scripts, and is three replies deep in an ExtendScript error. The script was written blind. With Prism the AI reads the project first, runs what it wrote in the live application and sees whether it worked.
What you say, and what lands
| You type | What appears in your project |
|---|---|
| "Rename every layer in this comp after the footage it uses." | Layer 1 to Layer 14 become the names of their sources |
| "Add a 12-frame fade in and fade out to every layer in this comp." | Opacity keyframes on each layer, at its own in and out points |
| "Find every comp that uses the old logo precomp and swap in the new one." | Each instance replaced, and a list of the comps it touched |
| "Duplicate this comp as a 9:16 version and bring everything into frame." | A new comp at the new size with the layers repositioned |
The script is the AI's problem, and it stays that way.

How to do it
Prompt and paste, and with Prism
| Prompt and paste | With Prism |
|---|---|
| Written from your description alone | The project is read first: real comp names, layer names, frame rate |
| You save a .jsx and run it from File, Scripts | It runs in the open application, from the chat |
| An error is a dialog you screenshot into the chat | The error returns to the AI, which fixes and reruns |
| A change is another file | A change is another sentence |
The commonest passes have their own pages: batch rename layers, replace text across comps, change the font of all text layers, change a colour across comps and multiple aspect ratios.
What it needs
| After Effects | 2024, 2025 or 2026, macOS or Windows |
| AI client | any MCP client: ChatGPT, Claude, Claude Code, Cursor, Codex and others |
| Plan | a Free account is enough; scripts use MCP actions, not Prism AI credits |
What it does not do
It will not modify the After Effects application, install plugins or scripts into it, or change your preferences. It does not run on a closed project: the project has to be open, with the panel signed in. It does not leave a .jsx on your disk; the next time you need the same pass, you ask again.
