Roblox's mobile-first AI game creation tab — describe a game in plain text and get a playable prototype, right inside the Roblox app.

Roblox Build is a mobile-first creation tab inside the Roblox app that turns a plain-language prompt into a basic, playable game. Roblox introduced it on July 16, 2026. You type something like "Let's make a cozy adventure game set in a dense forest," and Build generates an initial, editable version of the game — no programming required — which you can then refine and share.
Build is powered by a broad set of AI models, including both open-source models and proprietary Roblox ones, that together handle gameplay mechanics, environment, characters, visual style, and sound. It draws on Roblox's own generative stack — a 3D foundation model (Cube) and procedural models that turn text or images into 3D assets — rather than a single text-to-game model. Roblox frames Build as an extension of Roblox Studio, its long-standing desktop creation tool: the two share a back end, models, and chat history, so you can start a game in Build on your phone and keep enhancing it in Studio's deeper toolset later.
Roblox is rolling Build out cautiously. Select features, including the ability to publish, enter public alpha for users in New Zealand beginning July 28, 2026, with a plan to expand to more creators and regions over the following months. During the alpha, Build is available to age-checked users 9 and older; games that are published and pass Roblox's safety checks become globally available to age-checked users 16 and older. A base-level version of Build is free, with paid options aimed at power users.
The honest framing: Build is a game-creation tool, not a content or marketing tool. It generates a game you can play and publish on Roblox — it does not make the promotional clips, trailers, posts, or cross-platform content that get players to actually find and load that game. Discovery on Roblox is retention-driven ("if no one plays it, no one can find it"), which means the work of driving an audience to your experience lives entirely outside Build.
Build gives you a game; it does not give you players. On Roblox, discovery is ranked on retention — if nobody plays your experience, the algorithm never surfaces it — so the traffic that seeds those first plays comes from outside Roblox, on TikTok, YouTube Shorts, Reels, and the rest. That external promo layer is exactly what Kompozy generates. Screen-record a run of the game you built, drop the footage into Kompozy, and it becomes a whole launch campaign: Clipped Shorts cuts the most eye-catching moments into captioned vertical clips, Persona Shorts or a HeyGen avatar hypes the game to camera with a face-locked recurring identity, Carousel Posts turn screenshots into a swipe-through "here's what you can do," and Photo Posts, Quote Graphics, and native Text Posts round out the feed — every asset held to one voice by your Persona Brief.
The multiplier is distribution. Build publishes to one platform, Roblox; Kompozy fans a single gameplay recording into 25–35 finished outputs and schedules them across nine social platforms plus a devlog Blog Article and an Email Newsletter to your community, all from one queue with Autopilot and a per-post review pipeline. It reframes to 9:16 for TikTok and Shorts, 1:1 for the feed, and 16:9 for a YouTube trailer, so one afternoon of promo covers the launch everywhere the players actually are. Use Build to make the game; use Kompozy to make the audience that finds it.

No. Build creates and publishes a game on Roblox itself — it does not make trailers, short-form clips, carousels, or posts, and it does not publish to TikTok, YouTube, or other platforms. Because Roblox discovery is retention-ranked, you need outside traffic to seed plays, which is where a content engine like Kompozy comes in: it turns a gameplay recording into captioned clips, carousels, a devlog, and scheduled posts across nine platforms.
Studio is the established desktop creation suite with deep, professional tools; Build is the new mobile-first, prompt-driven entry point. They share a back end, models, and chat history, so you can start a game in Build on your phone and continue refining it in Studio — Build lowers the barrier to a first playable version, and Studio takes it further.
