Roblox launches an AI-powered game creation feature in its mobile app

Roblox is testing an AI tool called Build that turns text prompts into playable games right from the mobile app. It's starting small in New Zealand, but it could flood the platform with quick, AI-made games.

Roblox wants you to make a game the same way you'd ask a chatbot for a recipe: type a sentence, get a playable world. The company's new Build feature, announced Thursday, takes a prompt like "a cozy adventure game set in a dense forest" and spits out a working first draft, complete with mechanics, characters, sound and visual style. No code required. Users can then tweak it and push it out to friends, all from a phone.
Roblox says Build runs on a mix of open-source and its own proprietary models, which fits the platform's broader AI buildout. There's already a foundation model for generating 3D assets and a chatbot that walks developers through building games, and now there's a scene-generation model in the works that can produce an entire editable 3D environment from one line of text. Build is rolling into public alpha on July 28, but only for verified users age nine and up in New Zealand. Anyone 16 or older in that test group can publish to the wider world. A free tier will exist alongside paid options.
The timing is interesting, because Roblox is essentially wading into a fight that's already been raging in game development circles. Google, Microsoft and Tencent have all shipped similar prompt-to-game tools, and the reaction from working developers has been lukewarm at best. This year's Game Developer Conference survey found 52% of industry professionals think generative AI is actively hurting the business, not helping it. The fear is straightforward: if anyone can generate a passable game in seconds, the platform gets buried in forgettable, cookie-cutter content, and human creators end up competing against a firehose of AI output that took no time or skill to produce.
Roblox's answer is to lean on its existing discovery algorithm, which ranks games by retention rather than novelty. The pitch is that if nobody sticks around to play an AI-generated game, it simply won't surface on the homepage, so quality control happens after the fact through player behavior rather than before publication through gatekeeping. Whether that holds up once millions of casual creators start prompting away is the real test here, not the demo reel.
Roblox is also building AI agents to help with playtesting and analytics, expected in coming months, and separately confirmed it's shutting down Roblox Connect, its 2023-era avatar video calling feature. Two very different bets, same underlying theme: the company is putting a lot of chips on AI reshaping how its platform gets built and used.
My take — AI-written commentary, not fact-checked reporting
Ranking by retention sounds like a tidy fix until you remember Roblox's audience is mostly kids who will absolutely binge-play something shiny and hollow for a week straight, which is exactly the kind of signal that fools a retention algorithm. I'd bet the
