Rool Documentation

A Rool Space is a persistent, collaborative environment for organizing objects and their relationships. AI in a Rool Space operates on a structured world model — objects, schema, references — rather than a text conversation.

Extensions add features to a Space. Productivity tools, dashboards, data views, games — anything can be built as an extension and installed into a Space. Multiple extensions can run in the same Space, letting users and teams assemble an AI-powered interface that fits exactly how they work.

Getting Started

Rool is a chat-centered AI web app with object-based memory that can be customized with vibe-coded extensions. Sign up at rool.app and familiarize yourself with the environment. Create a few spaces, chat with them, add and remove objects. You can install example extensions like Chat, Flashcards, and Snake directly from the extension directory inside any Space.

When you’re ready to build your own extension, scaffold a new project with the CLI:

npm install -g @rool-dev/cli
rool extension create my-extension
cd my-extension && npm install && npm run dev

For detailed API documentation, read the Extension docs or point your coding agent at them.
