Roblox Introduces Build, an AI Tool That Lets Users Turn Text Prompts into Mobile Games

The company is launching a New Zealand public alpha and says discovery and safety checks will limit low-quality AI creations while opening game-making to more users.

Overview

  • Roblox announced Build as a mobile-first creation tab that will enter a public alpha on July 28 in New Zealand and allow age-verified users nine and older to create projects.
  • Build converts plain-language prompts into basic playable games by generating gameplay mechanics, environments, characters, visual style, sound, and functional 3D objects and scenes.
  • Projects started in Build share the same back end, AI models, and chat history with Roblox Studio so creators can begin on a phone and continue work on the desktop Studio.
  • Roblox says Build-created games must pass safety checks and extended review for Kids and Select catalogs and that its retention-based discovery system will limit visibility for creations that don’t hold players.
  • Developers warn that easier game generation could flood the platform with repetitive or low-quality projects and increase competition and moderation workloads, a concern echoed by a survey finding 52% of industry pros view generative AI’s effects negatively.
