Browser-based 3D design with AI-assisted scene generation
Spline makes 3D design feel closer to Figma than to Blender. Everything runs in the browser - modelling, materials, lighting, animation and physics - with real-time collaboration, so a web designer can build interactive 3D scenes without installing a heavy desktop package or learning traditional modelling terminology. AI features generate materials and textures from text descriptions and help set up lighting. Finished scenes export to the web with a small runtime library, which is why Spline output appears on so many modern landing pages.

No. Blender handles serious modelling, sculpting, rendering and animation pipelines. Spline targets web-ready interactive scenes where speed and browser delivery matter more than polygon-level control.
Far less than with traditional tools. Someone comfortable with design tools can become productive quickly, though understanding basic 3D concepts like axes, materials and lighting still helps.
