## Interior Design API

Interior Design API targets a specific audience: real estate and interior design platforms that want AI-powered visual features inside their own products. Rather than offering a consumer app, it exposes design and image capabilities through an API so development teams can generate room concepts, stage empty properties and enhance listing photography at scale.

The feature set covers the tasks that matter most in property marketing. The platform can generate interior and exterior design concepts, turn sketches into realistic visuals, virtually stage empty rooms, remove unwanted objects, convert daytime exteriors into evening scenes and upscale property images for sharper presentations. Bundling these into one API means a platform can support many visual workflows without integrating a different vendor for each capability.

Because it is an API product, the practical user is a developer or product team building a real estate or interior design service. The value comes from embedding these visual features directly into existing workflows — listing sites, design tools, property portals — rather than asking users to visit a separate app. Note that the public website is currently under a maintenance upgrade, so prospective customers should confirm current capabilities and commercial terms directly with the provider.

**Pricing & Plans:** Paid, with pricing available on request; current commercial terms should be confirmed with the provider while the site is under maintenance.

- **AI design generation:** Generate interior and exterior design concepts programmatically, so platforms can offer design ideas without bespoke tooling.
- **Sketch to reality:** Convert sketches, outlines and rough concepts into visually rich renders suitable for marketing and sales.
- **Virtual staging:** Automatically furnish and style empty rooms to help buyers and renters imagine a space as their own.
- **Image upscaling and enhancement:** Improve resolution and clarity of property imagery to make listing photos sharper and more consistent.
- **Day-to-dusk and item removal:** Turn daytime exterior photos into evening scenes and remove unwanted items from images to present properties at their best.

**Strengths:** Bundles multiple property-visual AI capabilities behind a single API; Covers both interior and exterior design generation; Includes commercial essentials like virtual staging and image upscaling; Lets real estate platforms embed visuals without building AI in-house

**Limitations:** The public website is currently under maintenance, so feature and pricing details cannot be verified live; API-based delivery means it suits developers and platforms rather than non-technical end users; Output quality depends on the quality of input photos and floor plans

## Spline

Spline brings 3D design into the browser so designers, developers and marketers can build interactive 3D without a heavyweight desktop pipeline. The editor covers primitives, booleans and sculpting, plus 3D generation, layered materials, lighting and post-processing. Animation and interaction are handled through states, keyframes, events and physics, and the whole file runs with real-time performance.

A standout feature is agent collaboration: you can connect assistants such as Claude, ChatGPT, Cursor or Codex through Spline MCP so an agent can read and write to the live scene, then hand it back to your team for refinement in the very same file. Because everything the agent produces is a regular Spline object, teammates can select, restyle, animate or undo it by hand at any point.

Publishing targets the modern web and mobile stacks. You can share a link, embed a viewer or export code for web (WebGPU/WebGL), add a native SwiftUI or Metal view for Apple apps, or build for Android with Vulkan and Jetpack Compose. Spline is used for interactive product design, brand and marketing pages, immersive experiences, gamified sites and education.

**Pricing & Plans:** Spline offers a free tier to start building in 3D, with paid plans for individuals and teams and a dedicated Enterprise offering. Exact seat and feature limits per tier are listed on the Spline pricing page.

- **In-browser 3D editor:** Model with primitives, booleans and sculpting, and use 3D generation to create objects from prompts.
- **Materials, lighting and post-processing:** Apply layered materials, lights and post-processing effects to give scenes a polished, production-ready look.
- **Animation and interaction:** Build interactivity using states, keyframes, events and physics so scenes respond to scroll, hover and other triggers.
- **Agent collaboration over MCP:** Connect AI coding agents to read, write and frame the live scene, then refine the same file by hand with your team.
- **Ship to web, iOS and Android:** Publish a link, embed a viewer, export code for the web, or create native Apple and Android views and builds.

**Strengths:** Runs entirely in the browser, so there is no heavy install or setup barrier; Real-time collaboration and agent workflows keep designers and developers in one shared file; One scene publishes to web, iOS and Android with platform-native renderers; Broad feature set spanning modeling, materials, animation, physics and interaction

**Limitations:** Advanced 3D work may still require a learning curve for newcomers; Performance and export options depend on the device and platform you target; Team and enterprise capabilities sit behind paid tiers
