Roblox adds AI tools to help creators plan, build, test games

Roblox is pushing deeper into AI-driven game making, turning Roblox Studio into what amounts to a quasi-studio system that can help creators plan, build and test experiences with less manual work. The company said 44% of the top 1,000 creators on the platform already use Roblox Assistant or third-party AI tools through MCP, a sign that the most active developers are already weaving automation into the production pipeline.

The newest update moves Assistant beyond one-step prompt responses and into a more collaborative workflow. In Planning Mode, Roblox said the tool analyzes a game’s code and data model, asks clarifying questions and turns a prompt into a detailed, editable action plan that can serve as a mini design document. Roblox said it plans to store that planning context across sessions soon after launch, so creators do not have to restart the conversation every time they return to a project.

On the build side, Roblox is adding Mesh Generation and Procedural Model Generation. Those tools are meant to create textured meshes and code-controlled assets with adjustable attributes, including details as specific as the number of shelves in a bookcase or the number of chairs around a table. On the testing side, Roblox is rolling out a playtesting agent beta, extending an effort to let AI iterate on games with less human back-and-forth.

The company is also making the automation stack more open inside Studio. Its built-in MCP server can let connected AI tools explore the data model, write scripts, run Luau code and test experiences in play mode. Roblox said in February that new MCP tools would allow agents to iteratively plan, write, test and modify games, and in March it described “agentic validation loops” that let Assistant playtest and fix its own work until it meets prompt requirements. Roblox also said Assistant can connect to external models from Anthropic, OpenAI and Google Gemini.

The pitch is straightforward: lower the friction of production and help creators ship faster. The business logic is just as clear. Roblox has spent the past year tying AI upgrades to monetization, including an 8.5% increase in Developer Exchange at RDC 2025, when it also announced first-of-their-kind AI capabilities, fully functional 4D objects, language tools and MCP integration into Assistant. Roblox said creators earned more than $1 billion through DevEx in the 12 months ending June 30, 2025, while the company continues to pursue its long-term goal of capturing 10% of global gaming content revenue.

That is why the new tools matter beyond convenience. If Roblox’s AI stack works as promised, it could widen the gap between creators who can industrialize production and everyone else. It could also flood the platform with faster-made, derivative content, even as Roblox bets that better tooling will expand creativity rather than dilute it.
