Spline AI

Spline is a browser-based 3D design platform with AI features for generating objects, textures and styles from text or images, embedded in a full editor for interactive scenes, animation and web publishing. It supports real-time collaboration, code export, and Apple/Android export on paid plans. AI is a paid add-on with monthly credits. It suits designers and developers building interactive 3D for websites and apps.

Spline is a collaborative, browser-based 3D design tool that lets designers model, animate and publish interactive 3D scenes for the web, no native software required. Its AI layer adds text-to-3D and image-to-3D object generation, AI texture generation and AI style transfer, so you can spin up assets and looks quickly inside the same environment where you compose and animate scenes. What distinguishes Spline is that AI generation lives inside a full design and publishing workflow. You can build interactive experiences with events and variables, collaborate in real time, and export to the web (with code export on paid plans) or to Apple and Android formats. That makes it popular with product designers, web designers and creative developers who want 3D on their sites and in their apps. Spline offers a free tier plus Starter (~$12/month billed yearly) and Professional (~$20/month) plans, with the AI capabilities available as a separate add-on (reported ~$5 per seat/month for 2,000 monthly AI credits). Upgrading removes export watermarks and unlocks unlimited files, code export, APIs and webhooks. It is less about generating standalone 3D assets and more about designing complete interactive 3D scenes with AI assistance.
