Spline AI

What is Spline AI?

Spline AI is an AI 3D generation feature within the Spline platform that creates 3D mesh objects from text prompts and from images. Its core purpose is to help you go from an idea or reference (concepts, sketches, or front-facing images) to usable 3D models without starting from manual 3D modeling.

It also supports remixing and variant generation so you can build a growing library of related 3D results over time. The workflow can happen in the Spline Editor or from a dashboard, and the generated content can be published to other platforms via Spline’s export options.

Key Features

• Text to 3D generation: Enter a prompt to generate 4 variants that can be turned into 3D models.
• Image to 3D generation: Use a 2D front-facing image as a reference to influence the generation and convert it into 3D models.
• Remix & variant generation: Create new results by remixing and referencing previous generations, supporting iterative exploration.
• Integrated generation workflow (Editor + Dashboard): Choose where to generate—while working in the Spline Editor or from a dedicated dashboard focused on building your 3D library.
• 3D library creation: Save and organize your generated outputs into a personal library for use across projects.
• Interactive exports for publishing: Export generated AI 3D content for web embedding (via a code snippet/custom code).
• Platform exports for Apple and Android: Generate outputs for Apple platforms (Swift code snippet or generated Xcode project) and Android (Kotlin code snippet, APKs, and AABs).

How to Use Spline AI

1. Start generation: Use Spline AI to generate from either text prompts or an image reference.
2. Review variants: For text prompts, generate 4 variants, then convert the result(s) into 3D models.
3. Iterate with remixing: Use remixing and referencing to create additional variants based on earlier outputs.
4. Continue in context: Generate while building scenes in the Spline Editor, or switch to the Dashboard to focus on building your 3D library.
5. Publish: Use Spline’s export options to embed content on the web or to produce Apple/Android outputs using the provided export paths.

Use Cases

• Concept-to-model for stylized assets: Generate multiple stylized 3D variants from short character or product prompts (e.g., characters, props, furniture) to find a direction quickly.
• Reference-driven 3D modeling: Turn a front-facing 2D image into a 3D model when you want your generation to reflect an existing reference.
• Iterative creative exploration: Build a set of related objects by generating, then using remixing and references to evolve the results while keeping continuity.
• Reusable project library: Create and maintain your own library of generated 3D assets so you can reuse them across different Spline projects.
• Multi-platform deployment: Embed AI-generated 3D content on the web, or export to Apple and Android workflows (including project/code outputs) for integration elsewhere.

FAQ

Can I use it for free? The provided page content includes a “Can I use it for free?” question in the FAQ, but it does not state an answer. You’ll need to check the FAQ details on the page for the current policy.

Do I need a high spec device to use Spline AI 3D generation? The page lists the question in the FAQ, but it does not provide an answer in the provided content. Refer to the on-page FAQ for device requirements.

How is this version of Spline AI different from the previous one? The page indicates “AI 3D Generation V1,” and includes a FAQ question about differences from the previous version, but the actual differences are not shown in the provided excerpt.

Is Spline AI using my existing files data? The FAQ includes questions about whether Spline AI uses existing files/data and how it uses your data, but no details are included in the provided content. Check the on-page FAQ for specifics.

Where can I generate—inside the editor or elsewhere? Yes. The page states you can generate from the Spline Editor while working on scenes, or from the Dashboard to focus on building your 3D library.

Alternatives

• Text-to-3D tools (model generators): Tools focused specifically on generating 3D from text prompts. These typically center on prompt-to-mesh workflows but may not include the same integrated editing and Spline publishing/export paths.
• Image-to-3D generators: Services/workflows that convert images into 3D using a reference image. They can be useful when you already have a front-facing image but may differ in how you manage variants and reuse outputs.
• 3D modeling software with AI-assisted workflows: Traditional modeling tools augmented with AI features. This can provide more manual control, though it may require more setup or 3D expertise than prompt/image-based generation.
• Interactive 3D web publishing platforms: Platforms that focus on placing and publishing 3D content to the web. Some may require you to generate assets elsewhere, while Spline’s approach combines generation and publishing in one workflow.
