What you need

• Roblox Studio with the UI AI Builder plugin (Plugins > Risor > UI AI Builder).
• Node.js LTS, free from nodejs.org.
• One AI option: Claude Code with a Claude Pro or Max subscription (nothing to paste), or an Anthropic API key.

Install

1. Install Node.js LTS (once).
2. Unzip the bridge anywhere on your computer.
3. Double-click start-bridge.cmd (Windows) or start-bridge.command (Mac) and keep that window open.
4. In Studio open Plugins > Risor > UI AI Builder. The first time, Studio asks if the plugin may access 127.0.0.1: allow it.
5. Pick your AI in the plugin's Settings (gear icon), describe your game and press Generate.

What it does and does not do

• Listens only on 127.0.0.1 (this computer) and refuses requests made by web pages.
• Your API keys stay in the bridge folder on your computer and are sent only to the AI provider you chose. They are never saved in your place.
• The AI can read only the files you attach in the plugin, nothing else on your computer.
• No telemetry: nothing is sent to Risor.
