Roblox Launches AI-Powered Build Tool for iPhone and iPad

Roblox is bringing game creation tools directly to its iPhone and iPad app for the first time, allowing users to build their own experiences without starting on a desktop computer. The company announced Build, a new feature that uses artificial intelligence to turn a simple text prompt into a playable game.



In a Roblox Newsroom blog post, the platform detailed how Build operates inside its mobile app. A user can type something like, "Let's make a cozy adventure game set in a dense forest with environmental obstacles," and Build will produce a starting point with gameplay mechanics, environments, characters, visual styling, and sound. Creators can then playtest the result, refine it using additional prompts, share it with friends, or publish it to Roblox.


Build is designed as a lower-friction entry point for the company's 132 million daily active users who may have a game idea but have never used Roblox Studio, its desktop creation tool. Build and Studio share the same backend, AI models, and chat history, allowing a project started on an iPhone or iPad to later be opened on a Mac or PC for more advanced work.

The feature will enter public alpha testing on July 28, beginning with age-checked users in New Zealand aged 9 and older, though age requirements may vary by region. Published games that pass Roblox's safety checks will be available globally to age-checked users 16 and older. They must also complete the platform's extended review process before entering its Kids or Select catalogs. A basic version of Build will be free, with additional paid options planned for power users.

Roblox says Build uses a mix of open-source and proprietary AI models. Its own models are trained on a large collection of 3D models and gaming-specific data, allowing them to generate functional objects and complete scenes that can be integrated into working games.

The company is also developing additional AI tools for professional creators, including agents that can identify bugs during playtesting, answer analytics questions in plain language, and recommend experiments intended to improve engagement, retention, and monetization. Roblox is separately preparing a scene-generation model capable of producing editable, playable 3D environments from a single prompt.


Addressing concerns about an influx of low-quality AI-generated content, Roblox said Build projects will enter the same candidate pool and be ranked by the same retention-based discovery system as all other experiences. Games that fail to attract and retain players will be difficult to discover.
