(01) Why use Rainbrand
Image models can make a striking campaign image, but they don't know your products, type or colours, and every new size starts from scratch. Rainbrand gives your agent a Brief for the campaign, with the guidance and product references every format needs.

What do I need to make a static ad set?
An agent connected to Rainbrand through MCP and a ready brand, or sources such as a website to create one. Your agent requests a Brief and generates the images through the AI Gateway with a model that supports reference images and the sizes you need. Connect Rainbrand to your agent.
What does the Brief add to the images?
The Brief selects the brand guidance and product references that matter for this campaign. When your agent passes its ID with each generation request, Rainbrand gives the model that guidance and the Brief's references alongside the prompt. Every format uses the same Brief. How Briefs work.
How do I get the same image in other sizes?
Pick the strongest image and pass it as a reference in separate 1:1 and 16:9 generations, with the same Brief. Ask the model to keep the product, copy and visual direction while it recomposes each format. Read the model's input schema first to check it accepts reference images and those ratios.
Can I use my own image tools instead?
Yes. The AI Gateway is optional. Your agent can pass the Brief's guidance and assets to the image tools you already use. Use your own tools.
How do I check the set before it goes out?
Compare each image with the Brief for brand fit, product fidelity, copy and composition, check that any text is exactly right, then look at the set together for consistency. To check an image against the brand, request a Review.
