What is Spline AI?

Spline AI is a web-based 3D design tool that combines traditional 3D modelling with artificial intelligence to make creating animated 3D graphics faster and more accessible. You design directly in your browser, then export your work for use on websites, in marketing materials, or interactive applications. The tool is aimed at designers, marketers, and developers who want to add 3D elements without needing specialised software or deep 3D expertise. The AI features help with tasks like generating objects, suggesting designs, or automating repetitive aspects of the modelling process. Because it runs in the browser, you can collaborate in real-time and publish work immediately to the web.
