Roblox announces Build, a mobile‑first AI‑powered creation tool that lets users generate game prototypes from text prompts, expanding its creator ecosystem with AI assistance.

Roblox has unveiled Build, a mobile‑first, AI‑powered creation tool that lets users generate game prototypes from simple text prompts, marking a major expansion of its creator ecosystem.

What Is Build?

Build is designed for on‑the‑go developers, allowing them to describe a game concept in natural language and receive a playable prototype within minutes. The tool leverages large language models and generative AI to assemble terrain, assets, and basic scripting automatically.

How It Works

Users type a prompt such as “a medieval castle with a dragon boss” and the AI generates a 3‑D environment, populates it with appropriate models, and adds rudimentary gameplay logic. The output can be further refined using Roblox’s existing Studio tools or edited directly on a mobile device.

  • Enter a text prompt describing your game idea
  • AI generates a prototype with terrain, assets, and basic scripts
  • Edit, test, and publish directly from your phone

Implications for Creators

By lowering the technical barrier, Build aims to attract a broader range of creators, including those without programming experience. Roblox says the tool will accelerate the prototyping phase, enabling faster iteration and potentially increasing the volume of user‑generated content on the platform.

Roblox also plans to integrate Build with its existing monetization features, allowing creators to monetize prototypes as they evolve into full games.

Build empowers anyone to bring their imagination to life, directly from a phone.

The rollout will begin with a closed beta later this summer, followed by a public release in early 2027.
