Roblox is letting iPhone and iPad users create games using AI for the first time, eliminating the need for a Mac or PC and knowledge of scripting languages. The company announced the new Build tool, which generates playable game prototypes from text prompts and lets creators iterate directly on mobile devices. The tool will roll out to the Roblox mobile app starting July 28 as a public alpha test in New Zealand, with expansion to additional regions in coming months.
Until now, creating a Roblox game required access to Roblox Studio, a desktop application that requires familiarity with Luau scripting and runs only on Mac or PC. Build removes that barrier entirely. A user writes a text description of what they want to build, the AI generates a working game as a starting point, and the creator can expand it with additional prompts or hand-editing. The entire workflow, from conception to uploading to the Roblox platform, can happen on an iPhone or iPad, making game development accessible to users who may only have access to iOS devices and want to explore game creation without the friction of learning traditional development tools.
Roblox’s approach avoids the trap of most AI generation tools where creating output that feels disposable. Build is backed by the same infrastructure as Studio, so work started on a mobile device can be refined in Studio on desktop, or vice versa. A creator can prototype a game idea on an iPad during lunch, then dive into Studio later to add complex mechanics, or Studio users can launch AI agents to handle routine tasks and check progress from their phone.
For 20 years, Roblox has been on a mission to remove limits on what gaming is – and what it can be.
Today, we’re introducing Build – a new way for anyone to create a game on Roblox from their phone. And we’re expanding AI-powered tools for developers of every level.

This architecture is important here because it turns mobile creation from a novelty into a genuine workflow option. Creators are not locked into what an AI can generate in a single pass and they can polish prototypes into full games using professional tools.
Roblox has 151.5 million daily active users, many of them children and teens who access the platform almost entirely through mobile apps. User-created games like Brookhaven RP, Adopt Me, and Dress to Impress have proven that the platform’s creator economy is both and lucrative. Build could unlock a new wave of game makers by eliminating the friction of learning desktop software or code.
Stef Corazza, who leads generative AI at Roblox after building Adobe’s 3D and AR platforms, designed Build as part of a broader shift toward “agentic” game creation where AI systems that can plan, execute, and verify game development tasks, not just fill in blanks. This is more ambitious than a text-to-game gimmick as Roblox is building the next generation of its creator tools around AI as a first-class citizen.
The barrier to entry for game development has never been lower. For creators who own only iPads and have never touched code, Build removes a significant hurdle. Whether Roblox can maintain moderation standards and content quality as the creator base expands will determine whether this genuinely reshapes the platform or remains a niche experiment.
