(01) Why review
Agents make more of your assets every day, and off-brand colours, the wrong fonts and stretched logos slip into what ships. Rainbrand checks any asset against your brand and tells your agent what to fix.
Evidence for every verdict
Checked against your palette, fonts, logos and voice.

How companies integrate Rainbrand into their agents and products.
All customer stories“We use Rainbrand to fetch each customer’s brand and generate accurate, on-brand creative for their ads. It means we don’t have to reinvent that part of the stack ourselves.”
“Rainbrand is our brand brain for our company and all our assets are generated from there. I don’t know what magic they’ve done but it’s worlds above other generation products and the MCP is delightful to use.”
“I have the ideas, but turning them into great design was always a struggle. Rainbrand makes me feel like the best designer in the world, and I don’t think I’ll need to hire one for the small stuff again.”

What does a brand compliance Review check?
A Review checks an asset against the selected brand's guidelines. Choose any of four checks: colours, typography, logo and copy. Each returns a verdict and a short reason, with evidence pictures where available. See how to request a Review.
How does Rainbrand tell whether an asset is on-brand?
AI identifies what to check. Tools compare colour values with the palette, render letters from brand font files for comparison, and measure logo shapes. AI interprets the evidence, including letter pairs and brand voice. The findings show what each verdict is based on.
Can I check designs made in other AI tools?
Yes. Start with a ready brand and submit an image of the asset, wherever it was made. That can be a design export, a page or slide screenshot, or a captured video frame. Send a public image link, upload the image, or use an existing Rainbrand image.
Can Reviews check our brand voice and exact wording?
Yes. The copy check reads visible text and checks spelling, requested wording and fit with the brand's voice and facts. For Gut Oggau, it caught missing wine names on a film end card. Claude added them, and the next copy check passed. See the example.
Does Rainbrand fix the problems it finds?
Your agent makes the changes with its own tools, using the Review's findings, then requests another Review. You can set a limit on revision rounds and have it stop when a finding needs your judgement. Read about keeping AI assets on-brand.
Can agencies review assets for different clients?
Yes. Each Review names the brand to check against. A team can hold as many brands as it needs, with each client's guidance and files kept separate. Your agents or product select the relevant brand for each request.
What happens when a check can't reach a verdict?
It returns uncertain, with a reason. Inspect the finding or provide clearer references. A logo shown in perspective, for example, may be unsuitable for a flat shape comparison. If there is no relevant element to check, the result is not applicable.
Rainbrand builds and maintains shared brand context for your agents and products.
