A brand kit is one brand’s summary, voice, colors, typefaces, logos, and reference media in one place. Melius builds it from the brand’s website, its guidelines PDF, or both. Your team can keep a kit for each brand it works with, shared by every member. One kit is your team’s default: Mel uses it on every canvas and in every new chat. You can switch any chat to another kit. Open your kits from Brand kits in the sidebar, under Library, or go to /brand-kit. The page shows every kit as a card, newest first, with Default on the default kit.

​
Build a brand kit

1

Add a source

On the Brand kits page, click New brand kit. Enter the brand’s Website (for example yourbrand.com), upload a PDF, or both. A PDF can be brand guidelines, a pitch deck, or a style sheet, up to 250 MB.
2

Click Build brand kit

Melius reads your sources and fills in the Summary, Colors, Type, Logos, and Media sections. This usually takes a few minutes. You can leave the page; a card in the sidebar tells you when the kit is ready.
3

Review each section

Fix anything that doesn’t match your brand. See Edit a brand kit.
4

Click Publish brand kit

Mel starts using the kit from your next prompt.
Your team’s first kit becomes its default. When you sign up with a work email, Melius starts reading your company’s website for you during onboarding. If a reading fails, the message says why, for example a website that blocks reading or a PDF with no colors or fonts. Fix the source, or upload your guidelines PDF instead, and click Build brand kit again.

​
Edit a brand kit

Changes to colors, type, logos, and media save as you make them. Mel uses them from the next prompt. To rename a kit, click its name at the top of its page, or choose Rename from its card’s menu on the Brand kits page.

​
Use brand kits with Mel

Every new chat starts with your default brand kit, shown above the chat box. Mel follows its guidelines in every prompt in that chat.
  • Use another kit in one chat. Click the brand kit above the chat box and pick another published kit. The chat keeps that kit when you come back to it. New chats and new canvases still start with the default.
  • Leave brand kits out of one chat. Click the brand kit above the chat box and choose No brand kit, or turn off Attach brand kit in the chat’s + menu.
  • Add it back. Turn on Attach brand kit in the chat’s + menu.
  • Put your logo on the canvas. Ask Mel, for example “Add our logo and two product shots from the brand kit.” Mel places up to 5 brand kit files per message.
  • Try a kit on a new canvas. In the brand kit’s menu, choose Try on canvas. A new project opens with the kit loaded and starters such as Create ads and Make graphics.
Change the default. On the Brand kits page, choose Set as default from a kit’s menu. To stop new chats from starting with the default kit, turn off Use brand kit in Mel by default in Settings → Agent → Brand kit. You can still add it to any chat with Attach brand kit in the chat’s + menu.

​
Update or archive a brand kit

Update. When your brand changes, choose Update brand kit from the menu. You can add a guidelines PDF to a kit read from a website, or point it at a new source. Mel keeps using the published kit until you click Review update and publish the changes. Each website can be read once a day. Archive. Choose Archive brand kit from the kit’s menu. Mel stops using it, and it moves to the Archive tab on the Brand kits page for everyone on the team. Chats that used it go back to the default. Archiving the default kit makes your most recently published kit the default. Open an archived kit to view it, and click Unarchive to use it again.

​
Who can change brand kits

Owners, admins, and editors can build, edit, publish, update, archive, and unarchive brand kits, and choose the default. Viewers can see them. Members limited to selected projects can’t use Try on canvas, because it creates a new project. See Members & roles.

Tips

  • Upload your guidelines PDF if you have one. The PDF decides your colors and typefaces. Add your website as well and Melius also collects logos and photography from it.
  • Keep only the colors you use. Six is the maximum. Remove accent colors you rarely use, since Mel treats every color in the palette as part of your brand.
  • Add product shots to Media. Clear, well-lit photos of each product keep generated products accurate. Name each one for what it shows, for example “Hero bottle, front”.
  • Upload licensed fonts. If a typeface is marked Licensed font, choose Upload font file from its menu so your designs use the real font.
  • Write the summary as a brief. Describe your voice and add a few taglines in your own words. Mel follows them in prompts, node titles, and copy.
  • Put rules in Context. For do’s and don’ts such as “Never show the product in direct sunlight”, add them to Context in Settings → Agent. Mel applies them alongside the brand kit.
