This is what a Brand Home looks like. Live CSS, AI builder instructions, and brand context all hosted at one URL. Point any AI tool here and your brand shows up consistently across every project.
Magenta-plum anchors the brand. Coral pops on emphasis moments. Linen and near-black handle surfaces.
One typeface. Five weights. Tight letter spacing on headings, normal on body.
Structure is what turns AI from a novelty into actual leverage. This is the body copy treatment for paragraphs, descriptions, and prose blocks.
Cursor, Lovable, Claude Projects, ChatGPT, v0. Same pattern works everywhere. Link the CSS, paste the prompt, generate on-brand output instantly.

You are building for Design Hacker. Use the brand at https://brandidentitykit.com/designhacker Read brand.css for tokens, context.md for voice, prompt.md for full instructions. Apply DH voice rules: no em dashes, no "not X, Y" patterns, short punchy sentences, specific numbers, confident framing.

Each tool behaves a little differently. Pick yours, copy the paste-block, run. Result is the same: on-brand output, every time.
ChatGPT will prompt for network access. Click Allow. After that it fetches brand.css and pulls the full design system in one shot.

Cowork's sandbox blocks external network requests. The hosted URL won't work. Use this inline-tokens block instead. Brand carries perfectly.
Build me a [page type] for [project description].
Use the Design Hacker brand. Inline tokens (since you can't fetch external URLs):

Voice rules (mandatory): NO em dashes, NO "this isn't X, it's Y" patterns, short punchy sentences, specific numbers beat vague claims, ALL CAPS on 1-2 words for emphasis, customer is the hero.
Banned words: synergy, game-changer, revolutionize, elevate, unleash, unlock, best-in-class, cutting-edge, robust, seamless, in today's fast-paced world.
Layout DNA: editorial magazine over generic SaaS. Tight typography, image-right hero, solid-fill primary button + outline secondary.
Output the full single-file HTML.
Use @web to inject the brand.css URL into Composer context, or paste the inline tokens. Cursor's Composer respects external URLs when web search is on.
@web https://brandidentitykit.com/designhacker/prompt.md Build me a [page type] for [project description]. Use the Design Hacker brand from the URL above. Link brand.css in the head: https://brandidentitykit.com/designhacker/brand.css Apply the voice rules and layout DNA. Output the full HTML.
Lovable CAN fetch external URLs but type system fidelity is loose. Use the inline-tokens block from the Claude Cowork recipe for the cleanest output.

v0 builds files into /public/ but its live preview shows the project root by default. After build, visit /public/[filename].html directly OR download the file.

Some AI tools sandbox their networks (looking at you, Claude Cowork). Download the files locally and drop them in your project folder. Works the same as the hosted version.
The voice rules at work. Same idea. Two outputs. One sounds like everyone. One sounds like Design Hacker.
"In today's fast-paced AI landscape, this isn't just a brand kit, it's a revolutionary solution that empowers entrepreneurs to elevate their workflows."
"Most brand kits hand you colors. This one hands you a SYSTEM. Live CSS, AI builder prompts, ready components. Plug it into Cursor and watch your brand show up everywhere."
All readable, all linkable, all hosted at the same root URL.
