Roblox launches mobile AI game maker despite developer fears
Roblox is letting users generate playable games from text prompts on their phones, a move that could flood the platform with AI content and squeeze the human developers who drive its economy.
Roblox announced a new feature called "Build" on Thursday that lets users create basic games on mobile devices using text prompts, eliminating the need for programming skills. The tool generates an initial environment, characters, and mechanics from simple instructions, which creators can then edit and share.
The system relies on a mix of open-source and proprietary Roblox AI models to handle everything from visual style to sound. While tech giants like Google, Microsoft, and Tencent have built similar text-to-game generators, Roblox is embedding the technology directly into a live, commercial platform.
This integration threatens to upend the platform's creator economy by drastically lowering the barrier to entry and increasing the speed of production. Human developers now face competition from a potentially endless stream of AI-generated content, raising legitimate fears of a saturated marketplace dominated by low-effort, repetitive titles.
The announcement highlights a widening rift between platform owners and digital workers over artificial intelligence. A recent Game Developer Conference survey found that 52 percent of industry professionals believe generative AI is having a negative impact on the sector, driven by concerns over quality dilution and the devaluation of skilled labour.
Roblox argues its algorithmic curation will act as a filter against low-quality output. “Our discovery systems are designed to highlight games with long-term retention, which doesn’t include AI slop. The quality of games on the homepage isn’t changing: If no one plays it—no one can find it. The goal across these new tools is to continue to accelerate creation across all experience levels,” the company wrote in a blog post.
The Build feature enters public alpha testing in New Zealand on July 28 for verified users aged nine and older, though only those 16 and up can publish globally. A free basic tier will be offered alongside paid options. Roblox is also developing AI agents to handle playtesting and analytics in the coming months, alongside a new model for generating entire 3D scenes from text.
The pivot to AI creation comes just after Roblox disclosed it is discontinuing "Roblox Connect," its 2023 avatar-based video calling service. The strategic shift signals a renewed focus on automating its core gaming infrastructure rather than expanding into social communication.
