Meet the Assistant
A built-in chat panel where Claude makes real edits to your scene. Bring your own Anthropic key — it stays in your browser.
Open in the interactive manual →The interactive version has full-text search, a table of contents, and light/dark themes.
The Assistant is a chat panel inside the editor where you describe what you want and Claude actually edits your scene — adding objects, recoloring, arranging, grouping. Each thing it does lands as a single, tidy Undo step, so you're always in control.
Bring your own key
The Assistant runs on your Anthropic API key, kept only in your browser and sent straight to Anthropic per request — it's never stored on the 3dCMS server.
- Get an Anthropic API key
Create one at console.anthropic.com. (This is the pay-as-you-go API, separate from a Claude subscription.)
- Paste it into Settings
Open Settings ▸ AI Assistant and paste the key (it starts with
sk-ant-). It saves as you type. - Open the Assistant
Windows ▸ Assistant. It flips out of its placeholder state the moment a key is present — no reload needed.
Prefer to drive 3dCMS from Claude Desktop or Claude Code on your existing subscription instead? That's the MCP server.
AI keys at a glance
3dCMS has three independent AI features, each with its own key and its own setup page — so if you're hunting for the right one to paste:
| Feature | Key | Set it up in… |
|---|---|---|
| In-editor Assistant (this page) | Anthropic API key — sk-ant-… | Settings ▸ AI Assistant (steps above) |
| AI generation — new models & materials | fal.ai key — key_id:key_secret | Turning on AI generation |
| Drive from Claude Desktop / Code | 3dCMS token — tdcms_… | Generate a token, then connect Claude |
The Anthropic and fal keys live only in your browser; the tdcms_… token authorizes Claude from outside the editor (the server keeps just a hash of it).
