Spline explained.
Spline is a 3D design tool that lives in the browser, aimed squarely at interactive web scenes: model, animate, add interactions, embed. Its AI features assist that workflow — turning references into simple scenes — rather than being the product. If your output is a website rather than an asset file, this is a different and often better tool.
What it does well, and where it stops.
- Genuinely excellent for interactive 3D on websites, with embeds and interactions built in
- Real-time collaborative editing in the browser
- Animation and interaction tooling that pure generators do not have
- Free tier that is usable for real projects
- You are modelling, not generating — the AI assists a design tool, it does not replace the work
- Weak at producing detailed standalone assets from a prompt
- No remesh, no print pipeline, no multi-engine generation

Spline, answered.
Is Spline an AI 3D generator?+
Not primarily. It is a browser-based 3D design and animation tool with AI assists. For generating a detailed asset from a sentence, a dedicated generator will get much closer.
Can I use Sculpty models in Spline?+
Yes — export GLB from Sculpty and import it into a Spline scene to animate and embed it.
