Rainbrand | The brand layer for agents
Rainbrand builds and maintains shared brand context for your agents and products.
CANVAS: 01
Manifesto
Agents do more of your work every day, but none of them have your brand. Rainbrand is brand infrastructure for your agents: one maintained system, plugged into the tools you already use.
Your brands, ready for agents.
Rainbrand turns brand identity, guidance and assets into shared context your agents and products can use and update.

## Frequently asked questions
### Asked, answered.
[All FAQs](/content/faq/index.html)
01
### How do I give ChatGPT, Claude, and other AI tools the same brand guidelines?
Add your brand to Rainbrand and [connect your AI tools](/content/integrations/index.html). For each task, your AI assistant requests a Brief with the brand guidance and assets it needs. Rainbrand works with ChatGPT, Codex, Claude, Claude Code, Cursor, Higgsfield and any other AI tool that supports MCP.
02
### When I update my brand, do my AI tools get the change?
Yes, once you apply the edit in Rainbrand, connected AI tools use the new version when they request a Brief for their next task. Ask your agent or use the API to [prepare an edit](https://docs.rainbrand.com/guides/edit-brand), then review and apply it. Existing outputs don't change.
03
### Can it check AI images against my brand guidelines, and what does it check?
Yes. Rainbrand checks work against your brand, including AI images, pages and slides submitted as visual captures. A [Review](https://docs.rainbrand.com/guides/request-review) checks logo, colours, typography and copy, with a verdict (pass, fail, uncertain or not applicable), a reason and evidence pictures where available. Your agents can use the findings to revise the work.
04
### How do agencies keep client brands separate?
Keep each client as a separate brand in your Rainbrand team, with its own guidelines, brand voice and assets. Your AI assistant requests a Brief for the selected brand, so client guidance stays separate. There's no limit on the number of brands you can add; adding a brand uses credits.
05
### What does it cost for a team?
Plans start at $20 a month for Plus with one seat; Pro starts at $35 a month with unlimited seats. Every plan includes API and MCP access; Max and Scale also include unlimited seats. Plans include credits for usage, including brand additions. There's no limit on the number of brands you can add. See [pricing](/content/pricing/index.html) for plans and usage costs.
06
### Why not use custom instructions, a custom GPT or a Claude Project?
Custom instructions, a custom GPT or a Claude Project can work when your brand guidance is only needed in one tool and you're happy to update it by hand. Rainbrand maintains shared guidelines and assets across connected AI tools, gives each task a relevant Brief and checks work against the brand through Reviews.
Rainbrand builds and maintains shared brand context for your agents and products.
