Rainbrand builds and maintains shared brand context from your websites, brand guides and files. Give your agents the guidance and assets they need for marketing campaigns, websites, slides, email, video, and more. Keep that context current as your brands evolve. Use it with Claude, ChatGPT, Codex or Cursor, or build it into your product through the API.
Agents can build websites, write campaigns, and generate images. But every new tool or conversation needs to learn your brand again.
So you keep uploading the same guidelines, finding the right logos, explaining your tone of voice, and correcting work that doesn’t fit. When the brand changes, you have to repeat those updates across tools.
We built Rainbrand to give agents shared brand context they can use and update across their work.
Start with a website, brand guide, or files. Rainbrand turns them into reusable identity, guidance, and assets. Connect it to agents like Claude or Cursor, or build it into your own product through the API.
An agent working on a landing page can get the relevant brand guidance and assets. Another working on a campaign can use the same brand. As your brand evolves, you can update that context for future tasks.
That’s what we mean by the brand layer for agents.
You can try it with 1,000 signup credits.
We’d love feedback from founders and teams using agents for brand work, and builders adding brand capabilities to their products. Where do your agents struggle most with getting a brand right?
I'm part of the team building Rainbrand and I'm super excited to launch today! 🎉
If you’re wondering what you can actually make with Rainbrand, we’ve put some worked examples in the docs:
- Motion graphics: two 15-second concepts with very different typography, animation, and sound.
- A launch deck: six slides built as editable artboards in Paper.
- A marketing campaign: three creative directions, then one direction carried across portrait, square, and landscape.
Can't wait to see what you all build with it!
Full disclosure: I’m on the launch team, and I know Ray, but I’m also a paying user, and a very happy one.
I’ve run some very different brands through Rainbrand: my open source project The GTM Co-Founder, which looks like a Windows 95 desktop; Lads2Dads, a dads’ support group here in Cork, Ireland, with a risograph and linocut style; websites for small businesses, including my wife’s yoga studio; and blog art for one of my own products.
None of them look alike, and the output looks like I dropped 100K on a design agency.
Can’t wait to see where Ray and the team take it.
congrats on the launch ray. agents drift on tone for me more than on colors, they write a headline that sounds like another product. a short list of words the brand never uses would help more than a long brand book
Shared brand context would help with the repeated uploads you described. I'd also want to see which version of the guidelines an existing draft used after the brand has been updated.

Who hunted Rainbrand?
Rainbrand was hunted by Garry Tan. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
