Train on the building blocks of a game.
We’re preparing original Luau examples for a planned training run. They cover the systems Roblox developers write again and again, from round timers to inventories and respawns.
We’re building a custom AI for Roblox to help turn the game mechanics you imagine into Luau scripts you can playtest in Studio. Bring your first obby idea or your team’s next big update.

“Remember my checkpoint” sounds simple. In a multiplayer obby, the game has to remember a different checkpoint for every player. That’s the level of detail we want our AI to understand.

One of our planned tests is a tycoon shop. If a player taps Buy twice on the same upgrade, do they get charged twice? We’ll check the model’s work against rules like that.
New to Studio? Start with one rule in your own words. Already shipping games? Keep the brief and Luau files together so your team can review a change and get back to testing.
Start with a familiar obby. Change one rule and you have a game idea your crew can try in Studio.
Each jump flips gravity. The ceiling becomes the floor.
One gap and a checkpoint are enough to try the idea.
Can they reach the checkpoint? Watch where they miss.
The best games start with a slightly ridiculous idea.
Pick a starting point. Put your spin on it.
A hands-on example, ready for your spin.
Your idea stays in this browser.
One room, two gravity directions, and a checkpoint worth reaching.
Build on your own. Bring the group chat.
Give everyone—and every agent—the right role.
Invite your collaborators. Make space for the builders, the scripters, and the friend with all the ideas.
Connect with API keys or MCP. Pick a preset or choose exactly what your agent can see and change.
Craft is a Roblox game creation workspace. Plan a game, organize Luau scripts, review changes, and playtest in Roblox Studio. We’re developing a custom AI specifically for Roblox; model training is planned.
Training is planned. We’re preparing original Luau examples and separate tests for the Roblox games people actually build. You can use the browser workspace today to plan a game, edit scripts, and decide what to playtest first.
Use Craft to shape the game brief, organize your Luau files, and review changes with your crew. Bring the scripts into Roblox Studio to see how your game feels and publish it when you’re ready.
You can start by describing your idea and organizing a game brief. If you already write Luau, you can work with project files and advanced tools. Reviewing and testing game code still matters, whichever way you start.
Try the idea playground, then carry your idea into a project. Guided planning, your brief, and editable source files work in the browser. The playground uses local examples and sends no AI requests.
Account workspaces support invitations and four roles: Owner, Admin, Editor, and Viewer. Owners and Admins can create API keys with Read, Write, or Custom permissions for an MCP client that supports authorization headers.
Guest projects are saved in your browser, so export important files before clearing browser data. Account projects use cloud storage. The landing-page demo runs locally and sends no AI requests; the workspace asks before including your brief or code in model context.
Your first project starts in your browser. No sign-up needed.
