Roblox has released an agentic AI feature for its Roblox Studio tool for game creators, which it claims will turn text prompts into a game design document which the tool can then implement and test. “Creators can just describe what they want and Planning Mode will break down every step to make it, take feedback to refine the details, and implement the plan,” the company said in a press release.
“Game development is a multistep, multidiscipline endeavor that requires continual exploration and iteration,” Roblox said in a blog post announcing the feature. “AI tools that intake a prompt and output a solution in one step can feel like shooting in the dark and often fail to truly capture a creator’s original intent. We’re introducing an improved Planning Mode to turn Assistant into a multistep, collaborative development partner that works with creators to analyze the game’s code and data model, ask clarifying questions, and turn a complex prompt into a highly detailed, reviewable, editable action plan.”
“Creators can add context and tweak the plan to make sure it reflects their intent before any changes are made. The plan serves as a mini game design document that agents can use to execute tasks in parallel and check their work against the original vision.”
The company also announced a new “playtesting agent beta” which would test the generated game against the original plan, “analyzing the code and data model, reading logs, and using the player character as an automated QA tester to verify behavior.”
The company said this process could be incorporated into future planning loops, “creating a self-correcting system that becomes more accurate over time.” It also said it would soon release a tool for procedural generation of game assets, which would enable users to generate a gameplay object which can then be easily scaled to fit space in the game world.
Earlier this week Roblox rolled out new child safety features and parental controls, shortly before it agreed to pay $10 million by the state of Nevada to settle claims over child safety. The firm is facing over 140 such cases, according to reporting by Reuters. The firm has also started requiring a paid subscription to publish games on its platform, which it cited as an additional safety measure but will also contribute to offsetting its heavy ongoing losses, which amounted to $316 million in the final quarter of 2025.
