Yes, ChatGPT can drive After Effects. You install the Prism MCP panel, copy your personal MCP URL from it, and paste that URL into ChatGPT once. From then on ChatGPT can read your open composition and write real, editable layers and keyframes into it.

Settings → Connectors → add a custom MCP server, then paste the URL the panel shows.
Custom connectors need ChatGPT's developer mode on a paid plan. Turn it on under Settings → Connectors → Advanced.
What to ask first
Once ChatGPT is connected, start with something small and checkable:
- "Tell me about my current composition." — proves the read path
- "Stagger these layers by two frames and ease them out." — proves the write path
- "Transcribe this audio layer into subtitles." — proves Prism AI
More in your first prompts.
If it does not work
| What you see | What it usually means |
|---|---|
| ChatGPT cannot reach Prism | The panel is closed. It has to be open in After Effects |
| It connects but sees no composition | No comp is active — open one |
| The URL is rejected | It was copied before clicking Connect. Click Connect, then copy |
| It asks for your license again | The key is not activated on this device |
The longer list is in troubleshooting.
Common questions
Do I pay for ChatGPT and Prism separately?
Yes, and that is deliberate. You keep your own ChatGPT subscription and Prism never resells model access — which is exactly why AI actions have no cap on Pro. See your AI client.
Does ChatGPT see my project files?
No. Your .aep files, footage and comps stay on your machine. Only the
structure of the open composition and the instruction you asked for make a
round trip.
Can I use ChatGPT and another client at the same time?
Yes. The same URL works in every client, so you can add it to as many as you like and switch whenever you want.
Can I undo what ChatGPT does?
Yes. Every action lands as one step in After Effects history, so a single undo reverts it, and anything destructive is preceded by a restore point.
