## Brick Generator

Brick Generator is a lightweight generative experiment rather than a full product suite. Its single page offers a text input where you type a simple idea — a house, a spaceship, an animal — and the tool generates a corresponding brick model you can explore in 3D. It is described by its makers as a proof of concept and 'the DALLE of bricks'.

Because it is an experiment, the results can be playful and unpredictable: simple, well-known objects tend to produce cleaner models, while abstract prompts give 'wild' output. There is no account, no library and no export pipeline advertised — it is meant for quick creative exploration and for demonstrating what text-to-brick generation can look like.

It is created by AE Studio, a product-development agency, and shown as a public demo of their generative-AI capabilities. There is no cost to use it and no pricing page, making it an easy zero-commitment way to experiment with text-to-3D block generation.

**Pricing & Plans:** Free to use. It is a public proof-of-concept demo with no paid tiers or pricing page.

- **Text-to-brick generation:** Type a short description and the model generates a corresponding building-block model in seconds.
- **3D brick models:** Output is presented as a 3D structure made of individual bricks rather than a flat image.
- **Simple prompt input:** A single input field keeps the workflow friction-free, with guidance to try simple objects for better results.
- **Experimental generative output:** Actively positioned as a work in progress, so results vary and can be creative or surprising.
- **No sign-up required:** The demo is open and free, so you can try prompts immediately without creating an account.

**Strengths:** Completely free with no sign-up or paywall; Instantly converts a plain text idea into a 3D brick model; Easy to use — a single prompt field, no 3D software skills needed; A fun, visual way to demonstrate generative AI to newcomers

**Limitations:** Explicitly a work in progress, so output quality and consistency vary; No export, library, or integration features advertised; Abstract prompts often produce unpredictable results

## 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
