Spline AI

What is Spline AI?

Spline is a web-based 3D design platform that enables users to create and collaborate on interactive, production-ready 3D experiences in real-time. The tool combines traditional design capabilities with AI-assisted features, including Omma, a natural language interface for generating interactive experiences, websites, and 3D assets from text descriptions.

The platform supports the full design-to-deployment workflow. Users can create 3D models using primitives and modeling tools, apply multi-layer materials from a library, and add interactivity through an event system supporting states, timelines, animation, physics, particles, and game controls. Real-time collaboration allows teams to comment, invite members, and work simultaneously on projects. Spline integrates with design platforms like Webflow, Framer, Wix Studio, and Hana (its 2D companion tool), plus supports native exports for iOS and Android apps. Developers can embed 3D scenes using HTML/JavaScript, React, Next.js, Swift, and Kotlin via the Spline Viewer component and API.

Spline operates on a freemium model with a free tier offering core design tools and community access. Paid plans provide additional features, with enterprise solutions available for teams at major organizations. The platform targets designers and developers across industries—brand agencies use it for interactive marketing, product teams build 3D mockups and prototypes, and developers integrate 3D experiences into web and mobile applications without requiring specialized 3D expertise. The learning curve is intentionally low; the company provides video tutorials, written documentation, a community library for remixing designs, and an academy for structured learning.

Real-time rendering, multi-platform export, and webhooks connecting to APIs and Variables enable dynamic, data-driven experiences. The tool reduces friction between design and engineering; designers create assets that engineers integrate without rebuilding from scra
