OnBrand gives AI agents design context through MCP. Add your brand guidelines, logos, colors, icons, imagery and slide rules, so tools like Claude, Codex and ChatGPT can create slides, infographics and design assets that actually match your brand. No more generic AI output, random layouts or off-brand visuals. OnBrand can generate your entire brand guidelines as a design.md from your existing website, existing branding guidelines or even PowerPoint templates.
