# Introduction
> Give agents and applications the brand context they need to create on-brand work.
Rainbrand is the brand layer for agents. It develops and maintains brand context that agents and applications can use across their work.
Start with whatever defines your brand: a website, brand guide, written requirements, logos, images, and more. Rainbrand develops the identity, voice, visual guidance, and assets that connected systems can draw on when creating a website, presentation, campaign, video, or other work. They can return to the same brand for the next task.
As the brand changes, you can add sources or describe an edit, inspect the proposed changes, and apply them. Your existing tools keep their role in creating and publishing the work.
## Start using Rainbrand
Add Rainbrand to an application or automated workflow. Authenticate, create
or choose a brand, and generate your first image.
Use Rainbrand from Claude, Codex, ChatGPT, or another MCP client. Connect
your account and ask the agent to work with your brand.
## See what a Brand Skill contains
A **Brand Skill** is a complete, versioned representation of your brand context, structured for agents to use. [Explore TANNIN's Brand Skill](/explore-brand-skill) to see its guidance, illustrations, logos, and other assets, or download the example to try with an agent.
