# Build brief — an original marketing website in the taste of Anthropic
> Reference: https://www.anthropic.com · UIDiscovery: https://uidiscovery.com/sites/anthropic · captured 2026-09-21 at a 1440px desktop viewport (+ 390px iPhone shots) · [full page](https://uidiscovery.com/media/captures/anthropic/full.webp) · [scroll video](https://uidiscovery.com/media/captures/anthropic/preview.mp4)
## 1. Goal
Build an original marketing website for **[the user's brand]** that feels as considered as Anthropic — same structure, rhythm and polish, entirely new identity and content.
## 2. Originality rules
- Build an ORIGINAL design for the user's own brand in the same *taste* as Anthropic: structure, rhythm, hierarchy, palette mood and type pairing.
- Never reuse Anthropic's logo, name, product imagery, illustrations, icons, screenshots or copy. Write new copy for the user's product.
- If the user hasn't said what their product is, ask first (or use clearly marked placeholders like [Brand], [Product], [Audience]).
- Reference screenshots are for looking at, not for embedding or tracing.
## 3. The taste, in short
- Anthropic (anthropic.com): AI marketing website, light, minimal.
- 5 sections: Hero → Content → Blog → Content → Footer.
- Spacing: about a screen per idea (median section ≈695px).
- Hero headline: 10 words — a full sentence; keep yours to one thought.
- Type: one family (Anthropic Sans). Imagery: mostly typography with little or no imagery, some photography.
## 4. Page structure (top to bottom)
### 1. Hero — state what the product is and for whom in one glance, and offer the primary action.
- Layout: headline-led stack: eyebrow → H1 → supporting line → actions, with a visual beside or below. Compact band (390px at 1440), own light band #f0eee6; no images (type-led); 4 text links instead of buttons.
- Slots: Eyebrow / announcement pill (optional); H1 (~10 words, like the reference); Supporting line, 1–2 sentences; Text link action; No image — let type and colour carry it.
- Topic (tone/length only — never reuse): “AI research and products that put safety at the frontier”
- [Screenshot](https://uidiscovery.com/media/captures/anthropic/s-01.webp)
### 2. Content — supporting content that deepens one idea.
- Layout: text + media block. Half to one screen (695px at 1440), own light band #f0eee6; 2 image/graphics; one primary button.
- Slots: Heading (~6 words, like the reference); Body copy; Supporting visual (see image plan); One primary action.
- Topic (tone/length only — never reuse): “:Claude: Fable 5.1 and Mythos 5.1”
- [Screenshot](https://uidiscovery.com/media/captures/anthropic/s-02.webp) · imagery: slot 1
### 3. Blog — signal an active, credible team through recent writing.
- Layout: 3-up card grid: image, title, meta. Half to one screen (699px at 1440), own light band #f0eee6; 3 image/graphics; 3 buttons (tabs, toggles or per-card actions); 4 headings → ~3 items under a title.
- Slots: Title + “All posts” link; 3 post cards: cover image, title, date/author.
- Topic (tone/length only — never reuse): “Latest releases”
- [Screenshot](https://uidiscovery.com/media/captures/anthropic/s-03.webp) · imagery: slot 2
### 4. Content — supporting content that deepens one idea.
- Layout: text + media block. Half to one screen (514px at 1440), own light band #f0eee6; no images (type-led); 6 text links instead of buttons.
- Slots: Heading (~10 words, like the reference); Body copy; Text link action.
- Topic (tone/length only — never reuse): “At Anthropic, we build AI to serve humanity’s long-term well-being.”
- [Screenshot](https://uidiscovery.com/media/captures/anthropic/s-04.webp)
### 5. Footer — navigation, legal and contact — the page's index.
- Layout: multi-column link groups, brand line, legal row. About one full screen (981px at 1440), own dark band #141413; 7 images/icons (a set of cards or a small gallery); one primary button, 92 links (link lists / navigation).
- Slots: Brand mark + one-line description; 3–5 link columns; Newsletter or contact (optional); Legal row + social icons.

## 5. Design system
### Colour
| Role | Hex | Use | Contrast on background |
|---|---|---|---|
| background | `#faf9f5` | page background | — |
| foreground | `#141413` | body text, headings | 17.5:1 |
| accent | `#141413` | none captured — monochrome. Primary buttons invert (foreground fill, background text); add your brand colour only for small highlights | — |
| surface | `#faf9f5` | cards, inputs, alternate bands | text on it 17.5:1 |
| muted | `#141413` | secondary text, borders | 17.5:1 |
Captured palette: `#faf9f5` `#141413`. Section bands top→bottom: `#f0eee6` → `#141413`. Roles are assigned automatically — sanity-check them against the screenshot. Keep the palette's *mood* (light, neutral, desaturated) and proportions; swap the accent for the user's brand colour.
### Tokens
```css
:root {
--background: #faf9f5;
--foreground: #141413;
--accent: #141413;
--surface: #faf9f5;
--muted: #141413;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
--radius: 12px; /* calibrate from the screenshot */
}
/* Tailwind v4 — in globals.css after @import "tailwindcss"; */
@theme {
--color-background: var(--background);
--color-foreground: var(--foreground);
--color-accent: var(--accent);
--color-surface: var(--surface);
--color-muted: var(--muted);
--font-heading: var(--font-heading);
--font-sans: var(--font-body);
}
```
### Typography
- Headings: **Inter** (Google Fonts) — reference uses Anthropic Sans. “Anthropic Sans” is likely a custom or licensed face. Inter is a neutral stand-in — pick a closer free match by eye from the screenshot.
- Body: same family — a single-family system; create contrast with size and weight, not a second face.
- Scale (starting point, sizes weren't measured — calibrate against the 1440px screenshot): display clamp(2.5rem, 5vw, 4.25rem), h2 clamp(1.75rem, 3vw, 2.5rem), h3 1.25rem, body 1rem–1.125rem / 1.6, small 0.875rem. Headings: tight tracking (-0.02em), line-height 1.05–1.15.
### Spacing & rhythm
Sections run ≈695px tall at 1440 (median; range 390–981px, captures cap at 1700px) — roughly a screen per idea. Start with 96–120px vertical padding per section on desktop and about two-thirds of that on mobile. The background changes 1 time down the page — use band changes to mark chapters. 8px spacing grid, 1200–1280px max content width, 24px (mobile) / 32–48px (desktop) gutters.
### Shape, depth & theme
Flat surfaces, hairline 1px borders in the muted colour, small radii (4–8px), almost no shadow. Read exact corner radius, border and shadow treatment from the screenshots. Light-first; for a dark mode use a near-black (not #000) background, ~90% white text, lift surfaces with lightness not shadow, re-check the accent.
## 6. Imagery plan
Measured from 3 section screenshots: mostly **typography with little or no imagery**, some photography (light, neutral, desaturated, AI). Still glance at the linked screenshots to match the exact mood.
### Slot 1 · 2. Content → photography
- Photography, seen in the capture (blue sky). (measured from the screenshot) Count: a set of ~2 in one consistent style. Aspect: 4:5. Look first: [ref 1](https://uidiscovery.com/media/captures/anthropic/s-02.webp)
- **Stock** — “3d glass shapes render”: [Unsplash](https://unsplash.com/s/photos/3d-glass-shapes-render?orientation=portrait) · [Pexels](https://www.pexels.com/search/3d%20glass%20shapes%20render/?orientation=portrait) · [Pixabay](https://pixabay.com/images/search/3d%20glass%20shapes%20render/?orientation=vertical)
- **Generate** — `Photograph: 3d glass shapes render. Composition: simple composition with one focal point. Lighting: soft natural daylight, airy and high-key. Neutral, desaturated colour grade that sits on #f0eee6, #141413, #faf9f5. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 4:5. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### Slot 2 · 3. Blog → illustration (uncertain)
- Light AI section with a few graphics — illustration, icon art or a product shot. Count: a set of ~3 in one consistent style. Aspect: 3:2. Look first: [ref 1](https://uidiscovery.com/media/captures/anthropic/s-03.webp)
- **Stock** — “technology flat illustration”: [Unsplash](https://unsplash.com/s/photos/technology-flat-illustration?orientation=landscape) · [Pexels](https://www.pexels.com/search/technology%20flat%20illustration/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/technology%20flat%20illustration/?orientation=horizontal)
- **Generate** — `Flat vector illustration: abstract gradient mesh, friendly simplified shapes, limited palette of #f0eee6, #141413, #faf9f5 plus one soft neutral, plenty of empty background, consistent line weight, neutral, desaturated mood. Aspect ratio 3:2. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- Uncertain: this could equally be photography, a product shot or icon art — open the reference screenshots and match what you see.
- **No imagery (type-led)** — 1. Hero, 4. Content: No imagery needed — type, spacing and colour do the work. If the screenshot shows a background graphic, rebuild it in CSS (gradient, grid, noise) or a short muted video, not a stock photo.
- **Icons** — 5. Footer: Use one open-source icon set at one stroke weight — Lucide, Phosphor or Heroicons (MIT) — tinted with the text or accent token. Social icons: Simple Icons.
### If the screenshots show a different style
Open the refs first and name what you actually see (photo / product UI / illustration / abstract gradient or 3D / type only). If it differs from the guess, switch routes — UI is built in code, type-only needs no image, otherwise:
- **abstract 3D / gradient** — generate `Abstract 3D render: soft, matte clay shapes and a smooth gradient in #141413 on a #faf9f5 background. Lighting: soft natural daylight, airy and high-key; neutral, desaturated tone. Minimal and calm, generous negative space on one side for text. Aspect ratio 3:2. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.` · stock: [“abstract gradient 3d” on Unsplash](https://unsplash.com/s/photos/abstract-gradient-3d?orientation=landscape) (same query works on Pexels/Pixabay)
- **Licences:** Unsplash and Pexels images are free for commercial use under their own licences; Pixabay under the Pixabay Content License. Check each image's page before use, credit the photographer when asked (good practice anyway), and skip images showing logos, trademarks, branded products or identifiable people without a release.
- **AI generation:** the prompts work with any image model (GPT Image, Imagen, Flux, Midjourney, Firefly, SDXL…) — check its commercial-use terms. Never put the reference brand's name or “in the style of <brand>” in a prompt.
- **Never** download, trace or re-host the reference's own images, illustrations, product shots or logos.
## 7. Build steps
1. Confirm brand, product, audience and the primary action with the user.
2. Set up the tokens (CSS variables / Tailwind @theme) and load the fonts.
3. Build the sections in order, mobile-first, with each reference screenshot open.
4. Write original copy for every slot — match length and tone, never the words.
5. Source every image via the imagery plan (stock or generated); compress it and record credits.
6. Run the checklist at 390 / 768 / 1440px and fix what fails.
## 8. Acceptance checklist
- [ ] Responsive at 390px, 768px and 1440px — no horizontal scroll, tap targets ≥ 44px on mobile.
- [ ] Colour contrast WCAG AA: 4.5:1 body text, 3:1 large text and UI; visible focus states; full keyboard navigation.
- [ ] Semantic HTML: one <h1>, ordered headings, landmarks (header/nav/main/footer), labelled form fields, alt text on meaningful images.
- [ ] Performance: modern image formats with width/height set, lazy-load below the fold, ≤ 2 font families with font-display: swap, LCP < 2.5s.
- [ ] prefers-reduced-motion respected; animations under ~300ms and never blocking content.
- [ ] Originality: no copied logos, images, illustrations or copy from the reference; every image licensed or generated; credits recorded.
## 9. If you use Next.js + Tailwind
Paste the @theme block into globals.css, load fonts with next/font/google, make each section a server component in components/sections/, use next/image with explicit sizes, and keep client components for interactive bits only (menus, toggles, accordions).
