Build Roblox games by describing what you want. Scripts, UI, instances, animations and monetization, all created and applied directly in Studio from a single conversation.
How It Works
You chat, Metain builds. Every change goes straight into your Studio session through our open-source plugin while you stay in control.
-
Get the plugin and open it in Studio
-
Grab a connection code from the website
-
Start building
That’s it. No downloads, no setup files, no API keys needed.
What You Can Do
Scripts, UI, Instances & Properties
Describe what you need. Metain creates, reads and updates scripts, builds UI, manages instances, edits properties, tags and attributes. It reads your existing game structure and works with what you already have.
Monetization: Developer Products, Gamepasses & Badges
Monetize your game directly from the chat. Tell Metain what you want to sell and it creates the developer products, gamepasses or even badges on your experience. It sets the price, writes the title and description and implements the MarketplaceService logic in your scripts.
For gamepasses and badges, drop an image into the chat and Metain creates it with that icon, puts it on sale and integrates everything for you. One prompt, fully implemented.
To enable this, sign in to Metain with your Roblox account through OAuth and select the experience you want to work with during authorization.
Animation Editor (Beta)
We’re building a web-based animator directly into Metain. Upload a video and it extracts the motion into Roblox-compatible keyframes.
Currently available:
-
Video-to-animation conversion
-
3D preview with bone-level editing, import an existing animation to refine it or tweak the one from video for better results
-
Trim, mirror, reverse and loop-fix tools
-
Animation priority control (Idle through Action4)
-
Undo/redo for every edit
-
Export directly to your Roblox account or download as
.rbxmx
Once exported, go back to the chat and Metain can immediately reference your animation and set it up with the scripts you need. Walk cycles, emote systems, cutscenes, whatever you’re building.
This is actively being developed. More features coming soon.
Game Exploration & Debugging
Metain can also explore your properties and check services. Anything you’d spend hours digging through manually, done in a single conversation. Useful for debugging, auditing or just understanding a place you didn’t create.
Open Source Plugin
The Studio plugin is fully open source. You can read every line of code, verify what it does and contribute if you want to.
It only connects when you provide a connection code. It only modifies things inside your Studio session. Every action is saved in the undo history so you can revert AI changes without touching your manual work.

Under the Hood
Metain is powered by Anthropic’s Claude, currently running on Claude Opus 4.6, the latest and most capable model available. As Claude improves, Metain improves with it. The AI is built on deep Roblox development expertise covering scripting patterns, game architecture, data persistence, security practices and common pitfalls. The code it writes follows the same standards you’d hold yourself to.
