TL;DRRoblox launched Build, a mobile-first AI creation tab that generates games from text prompts, starting alpha in New Zealand on July 28.
Roblox announced Build on Wednesday, a new creation tab inside the Roblox mobile app that lets anyone turn a text prompt into a basic playable game without touching Roblox Studio or writing a line of code. A creator can describe something like a cozy forest adventure game with environmental obstacles, and Build will generate a starting point with gameplay mechanics, environment, characters, sound, and visual style. The feature begins public alpha testing in New Zealand on July 28 for age-verified users nine and older.
Build shares a back end with Roblox Studio, meaning creators can start a project on their phone and continue refining it on desktop with the full Studio toolset, or launch agents from Studio and check progress from mobile. The system is powered by a mix of open-source and proprietary Roblox AI models trained on what the company describes as a uniquely large set of 3D models and gaming-specific data. Roblox’s Cube foundation model, which the company introduced earlier this year alongside agentic Studio tools, generates game-ready objects that can drive, shoot, or otherwise behave as expected without manual scripting.
