▸ making roblox games with promptblox

PromptBlox is a Roblox AI game maker for creators 13 and older. You describe a game in chat, PromptBlox builds the world and its gameplay scripts in your browser, and you keep refining the same saved project. When it is ready, export the place to Roblox Studio to playtest and publish.

Yes. Describe your idea in chat or add a reference picture, choose a build level, and use the concept picture and 3D preview to see it take shape. You can ask for changes as you develop your game. Build time varies with the size of your idea and the build level you choose. Open the exported world in Roblox Studio to test its gameplay and make final adjustments.

When your build has a world to export, download the .rbxlx place file and open it in Roblox Studio. The file contains the world and scripts included in that saved version. Check how it plays in Studio, make any needed changes, and publish when you're ready.

Any game idea can be your starting point. PromptBlox V2 has no templates or fixed game types, so describe the world, its atmosphere, and how you want people to play. You can combine genres, invent new mechanics, or create something entirely your own. Describe any pets, characters, vehicles or props as part of the same idea. Watch your world take shape in 3D, refine it in chat, and take it into Roblox Studio to playtest and keep building.

You can create and preview your world in the browser without installing Roblox Studio. Use the 3D preview to inspect its appearance and ask for changes in chat. Use Roblox Studio on a compatible computer to test gameplay, make final adjustments, and publish your game to Roblox.

Roblox's Assistant helps inside Roblox Studio with a place you already have open, and Roblox Build is an AI creation tool in the Roblox app that Roblox is testing in a few countries. PromptBlox starts from your idea in the browser, keeps a saved project you refine in chat, and exports a place file you open in Studio.
