Roblox Launches AI Tool 'Build' for Text-to-Game Creation

Roblox is testing a new AI-powered feature called Build that lets users create mobile games simply by typing text prompts—no coding required. The tool enters public alpha on July 28, with initial access limited to verified users in New Zealand aged 9 and older. Once published, games will be playable globally by users 16 and older.

What Build Does

Build allows users to generate a basic game directly within the Roblox mobile app by describing what they want. The AI handles core elements including:

Gameplay mechanics
Environment and characters
Visual style
Sound design

The feature is powered by a combination of Roblox's proprietary AI models and open-source models. It joins a broader suite of AI tools Roblox has been developing, including a preview of an AI world model (similar in concept to Google's Project Genie), a foundation model for generating 3D game assets, and an AI assistant chatbot to help developers during the build process.

A base-level version of Build will be free to use, with additional paid options planned for power users—though Roblox has not yet disclosed specific pricing or feature details for that tier.

What's Coming Next

Roblox says it plans to roll out additional AI agents in the coming months focused on playtesting, analytics, and experimentation, aimed at helping creators improve engagement, retention, and monetization. The company has also confirmed that games created with Build will be ranked using the same retention-based criteria applied to other Roblox experiences.

Separately, Roblox disclosed plans to discontinue Roblox Connect, its avatar-based video-calling feature introduced in 2023. No timeline was given for this change, nor is it clear whether it's directly related to the Build launch.

Competitive Context

Roblox isn't alone in this space—Google, Microsoft, and Tencent have all built similar AI-powered game creation tools, suggesting text-to-game generation is becoming a broader industry trend rather than a one-off experiment.

Risks and Skepticism

Not everyone is convinced this is a net positive. Critics argue that lowering the technical barrier to game development could flood the platform with low-quality or repetitive games, and creators may face increased competition from AI-generated content that can be produced far faster than human-made games.

This skepticism isn't isolated to Roblox: according to the GDC State of the Game Industry survey, 52% of game industry professionals view generative AI's impact on the industry as negative—a sentiment Roblox will likely need to navigate as it expands Build.

Why Founders Should Care

For early-stage founders, this launch likely signals a few things worth watching:

No-code AI creation tools may be gaining real traction. Roblox's move suggests platforms are increasingly betting that text-to-product interfaces can meaningfully lower barriers for non-technical users—a pattern founders building creation tools elsewhere may want to track closely.
Freemium-plus-power-user pricing could become a common model. The free base tier paired with paid advanced features hints at a monetization approach that may prove replicable for other AI-powered SaaS products.
Quality control could become a market gap. Given the concerns from industry professionals about low-quality AI output, there's a plausible opportunity for startups building moderation, curation, or quality-scoring tools for generative content platforms.
Specialized AI agents for developer workflows may be an emerging category. Roblox's plans for AI-driven playtesting and analytics agents point to a broader shift toward AI-assisted tooling in gaming and SaaS—an area founders in those sectors should probably keep an eye on.
