What if you could create an entire interactive 3D scene without opening Blender, writing Three.js code, or manually building every object?
And what if you could edit the result directly inside ChatGPT?
Meet the new Spline plugin for ChatGPT and OpenAI Codex.
And this is exactly the kind of AI integration I've been waiting for.
Here's the idea.
Instead of asking ChatGPT to generate 3D code and hoping everything renders correctly, you connect it directly to a real 3D design application.
Spline's editor opens right next to your conversation.
You describe what you want, and ChatGPT builds the scene while you watch.
Here's what you can create:
Interactive 3D scenes: Objects, materials, lighting, cameras, and animations.
Product configurators: Interactive 3D products with customizable colors and materials.
3D interfaces: Animated music players, dashboards, and product demonstrations.
Interactive games: Simple playable 3D experiences.
Websites and app interfaces: Design layouts using Spline's Hana editor.
AI-generated assets: Create 3D models and images directly within your workflow.
Shareable experiences: Publish your finished scene and get a public link.
But here's where things get really interesting.
You and ChatGPT can edit the same project together.
Ask ChatGPT to create a 3D chair configurator.
Then manually rotate the chair, change its material, or adjust the lighting in the Spline editor.
Now tell ChatGPT:
"Add three color options and animate the chair when users select a different material."
ChatGPT reads the updated project and continues working from your changes.
No starting over. No losing your manual edits.
And the result isn't just another AI-generated image or video.
It's a real, editable Spline project saved to your account.
You can open it later, modify it manually, continue the conversation, or publish it online.
How to get started with ChatGPT:
Open the Spline plugin in ChatGPT's plugin directory.
Connect your Spline account.
Describe the 3D scene or interface you want.
Watch the editor build it.
Continue refining the same project through conversation.
No installation. No API key.
The integration uses Spline's hosted MCP server and includes the Spline Agent Skill, which teaches ChatGPT how to work with the editor.
And yes, it works with OpenAI Codex too.
You can install the same plugin or connect the MCP server manually:
codex mcp add spline --url https://mcp.spline.design/mcp
codex mcp login spline
The plugin works across Spline plans, including Free, although AI actions count toward your plan's daily usage limits.
Why do I find this exciting?
Because we're finally seeing AI agents integrate with actual creative software instead of constantly reinventing simplified versions of it.
You don't need another AI-generated mockup that becomes useless the moment you want to change something.
You need editable projects.
Real tools.
And an AI agent that can collaborate with you inside them.
The future of creative AI shouldn't be about replacing designers with prompts.
It should be about giving designers tools that can turn ideas into working, editable experiences much faster.
And Spline's integration with ChatGPT and Codex is a very interesting step in that direction.
