Roblox has announced Build, a new mobile-first creation experience that will allow users to turn text prompts into playable games directly within the Roblox app.
The company is also introducing a collection of AI-powered tools designed to assist both first-time creators and experienced development teams with game creation, testing, analytics and optimization.
Build will appear as a dedicated creation tab inside the main Roblox app. Users will be able to describe the type of game they want to make, and Roblox’s AI systems will generate a basic playable experience that can be refined, tested, shared with friends or published to the platform.
For example, a user could request a cozy adventure game set in a dense forest with environmental obstacles. Build would create an initial game based on that description, giving the creator a foundation to modify rather than requiring the entire experience to be assembled manually.
The process is organized around four primary stages: prompting, refining, playtesting and sharing.
Build is powered by a collection of AI models capable of generating and coordinating gameplay mechanics, environments, characters, visual styles, sound and other components of an interactive experience.
The new feature extends some of the capabilities of Roblox Studio into the company’s main consumer application.
Roblox Studio is the company’s free development environment used by creators to build and publish games. While Studio offers a broad range of professional tools, it can require more technical experience than many casual Roblox users currently possess.
Build is intended to lower that barrier by allowing people to begin creating through natural-language instructions on a mobile device.
The Build and Studio environments will share backend infrastructure, AI models and conversation history. This will allow users to begin a project through Build and later continue developing it with Roblox Studio’s more advanced capabilities.
Professional creators will also be able to launch AI agents from Studio and check their progress from a mobile device.
This connection is designed to make creation more flexible by allowing developers to move between mobile and desktop workflows without losing the context associated with a project.
Roblox is also testing agentic tools that can complete selected development tasks with limited supervision.
The tools are intended to help creators delegate repetitive or time-consuming work that does not require their full attention.
A planned playtesting agent will examine a game and identify bugs before players encounter them.
Automated playtesting could help developers evaluate more scenarios than they would be able to test manually, particularly as games become larger and receive frequent updates.
Roblox also plans to introduce an analytics agent that will let creators ask questions about a game’s performance using natural language.
Rather than searching through several dashboards, a developer could ask about player behavior, engagement patterns or areas where users commonly leave the experience.
The agent would then analyze the available information and return relevant insights.
A separate experiment agent will recommend tests intended to improve player engagement, retention and monetization.
The system could help creators identify changes worth evaluating, organize experiments and interpret the results without requiring them to build every analysis workflow independently.
Roblox expects the agentic tools to become available across Build and Studio in the coming months.
The company said these features are intended to remove friction for professional developers while also giving inexperienced users a more accessible entry point into game creation.
Build forms part of Roblox’s broader investment in generative AI tools for three-dimensional content and interactive experiences.
The company recently introduced Procedural Models, which can generate customizable 3D assets from a text prompt or reference image.
Unlike a fixed generated object, these parametric assets can be restructured and refined by changing defined properties. This gives creators greater control without requiring them to model each variation manually or regenerate the entire asset.
Roblox has also developed Cube, its own 3D foundation model.
Cube can transform a text prompt into game-ready objects ranging from simple environmental props to interactive vehicles capable of driving.
The company plans to introduce another AI model that can generate entire editable and playable 3D scenes from a single prompt.
Together, these tools are intended to reduce the gap between a creator’s idea and the technical work required to turn it into a functioning Roblox experience.
Roblox believes generative AI could substantially expand the number of people capable of creating games on its platform.
Traditional game development may require knowledge of programming, 3D modeling, animation, audio production, level design and testing.
Build will not eliminate the need for those skills in more sophisticated projects, but it could automate enough of the initial process to help new creators produce a playable starting point.
More experienced developers may use the platform to prototype concepts, test gameplay ideas or automate routine production tasks before completing more detailed work in Studio.
Roblox plans to make selected Build features available through a public alpha in New Zealand beginning July 28, 2026.
The company will gradually introduce Build to additional creators and regions as it evaluates usage and expands the platform’s capabilities.
During the testing period, Build will be available to age-checked users aged 9 or older, although age requirements and availability may vary by region.
Games published through Build that pass Roblox’s safety checks will initially be available globally to age-checked users aged 16 or older.
Build-created games will need to undergo an additional review process before they can be included in the Roblox Kids or Select catalogs.
The games will enter the same candidate pool and be evaluated under the same retention-based discovery system used for other Roblox experiences.
This means Build-created games will not automatically receive preferential placement simply because they were generated using Roblox’s new AI tools.
A basic version of Build will be available at no cost to creators. Roblox also plans to offer paid options for power users who require additional capabilities.
The tiered approach could allow casual users to experiment with game creation while providing more advanced creators with access to expanded AI tools and production capacity.
The new tools could also expand the supply of Roblox games by enabling ideas to move from text descriptions to playable prototypes more quickly.
Roblox describes its platform as both a gaming and creation environment where users can explore, develop, and share interactive experiences.
Build represents the company’s latest effort to make the creation process accessible to a broader audience while providing established developers with AI tools that can accelerate production and improve game performance.
“Today’s announcement is putting new tools in creators’ hands no matter their level of experience. Our new agentic tools help remove the friction for professional creators while Build opens the door to creation for everyone on Roblox and the opportunity to reach millions of users with their games.”
Vlad Loktev, Chief Creator Ecosystem Officer at Roblox
