Spline AI is a browser-based editor for making 3D scenes and 2D designs, with AI tools for generation and editing. It is for designers, developers and other creators who need to build visual assets, animated graphics or interactive scenes without separating every step into a different tool. The editor brings modeling, materials, animation, interaction and publishing into a shared workflow, while Hana provides a 2D canvas for interfaces and animated graphics. Spline also supports collaboration, with some workspace features depending on plan.
What can Spline AI do?
AI 3D Generation creates models from text prompts, reference images or both. Other AI features include an editor agent that can create objects, materials, lighting, animation and interactivity, as well as AI texture generation. Generated models use workspace AI credits, and the credit cost depends on the operation and agent-run complexity.
The browser-based editor includes modeling, sculpting, materials, lighting, cameras, timeline and state animation, particles, physics and Gaussian splatting. Creators can set up no-code interactions with states, events and actions, then connect scenes to data and services using variables, API requests, webhooks and real-time endpoints. The Code tab supports HTML, CSS and JavaScript, with a Spline API for scene interaction.
- Design interfaces and animated graphics on Hana’s 2D canvas, including with AI-assisted screen design.
- Publish scenes as web URLs or embeds, or use code exports and supported 3D file formats.
- Collaborate through shared editing and comments, with workspaces, projects and file version history.
- Use the Spline MCP Server with supported MCP clients, subject to plan-based daily call limits.
Who is Spline AI best for?
Spline suits people building interactive 3D scenes, animated web content, product visuals, interface designs or other visual experiences that combine 3D work with publishing. Developers can connect scenes to data or add code, while designers can use no-code interactions and Hana’s 2D canvas. Teams can consider its shared editing and comments, keeping in mind that some workspace features depend on plan. It may be less suitable when a project requires precise generated geometry or complex compositions: Spline cautions that generated results can have issues.
Spline AI pricing in brief
Spline offers a free version alongside paid tiers and an annual-billing enterprise option. Allowances and exports vary by tier: the free plan has limited personal files and watermarked web exports, while paid plans include differing AI-credit and MCP-call allowances. Some export options are available only on specified tiers. AI access is metered through plan credits rather than a separate AI add-on, and unused monthly credits do not accumulate.
Limitations to know about Spline AI
AI 3D Generation is a paid feature and consumes workspace credits; a generation can use credits for image previews as well as mesh generation. Credit costs vary, and the reviewed documentation does not give a fixed cost for each operation. Generated results may have bugs or other issues, and detailed assets can slow scenes containing several of them. The Free plan limits personal files, adds a watermark to web exports and does not include AI features in the plan comparison. Export availability also varies by tier.
Alternatives to Spline AI
If you are comparing creative tools, consider Adobe Firefly and Canva alongside Spline. The supplied comparison set groups both with Spline, while Spline’s documented focus is building 3D scenes and 2D designs in one editor. Compare the tools against your actual deliverable: interactive 3D scenes, 2D interface work, animation, collaboration or publishing. Check each listing for its current capabilities before choosing; this description does not assume feature parity or make claims about the alternatives’ tools.
