How Melius launched Brand Kits on X

Brand Kits is a new Melius feature that gives its creative agent a reusable set of visual rules, so images and video stay consistent without a new style brief on every job. It is aimed at independent creators and at creative directors inside large companies. You type a website URL or upload guidelines, and the agent sets up the kit from that material and applies it while generating work on the canvas. Melius is a New York company founded by Joowon Kim, Young Kim, and Arnav Ramu, who previously worked together as engineers at Ramp. Its product is a node-based canvas where an agent named Mel takes a plain-language brief, plans the steps, and routes each step to models such as Nano Banana, GPT Image, Seedance, Veo, and Kling, with every prompt left open to edit. Teams use it for campaign variants, pack shots, storyboards, and short video. The documented way to keep a look consistent has been a written brief dropped into a text node and wired into each generation. The launch is a partnership with Taste Labs, which is building tools so agents produce work that matches a brand. Taste Labs' Brand API extracts a brand system from a website URL, including color, typography, spacing, and layout, and can check whether later outputs still match. On Melius, brand kits are described as guidelines stored in reusable agent skills, so the same rules can follow a team across canvases rather than being recopied for each campaign.
