# Design System Inspiration of Cursor

## 1. Visual Theme & Atmosphere

Cursor's website is a study in warm minimalism meets code-editor elegance. The entire experience is built on a warm off-white canvas (`#f2f1ed`) with dark warm-brown text (`#26251e`) -- not pure black, not neutral gray, but a deeply warm near-black with a yellowish undertone that evokes old paper, ink, and craft. This warmth permeates every surface: backgrounds lean toward cream (`#e6e5e0`, `#ebeae5`), borders dissolve into transparent warm overlays using `oklab` color space, and even the error state (`#cf2d56`) carries warmth rather than clinical red. The result feels more like a premium print publication than a tech website.

The custom CursorGothic font is the typographic signature -- a gothic sans-serif with aggressive negative letter-spacing at display sizes (-2.16px at 72px) that creates a compressed, engineered feel. As a secondary voice, the jjannon serif font (with OpenType `"cswh"` contextual swash alternates) provides literary counterpoint for body copy and editorial passages. The monospace voice comes from berkeleyMono, a refined coding font that connects the marketing site to Cursor's core identity as a code editor. This three-font system (gothic display, serif body, mono code) gives Cursor one of the most typographically rich palettes in developer tooling.

The border system is particularly distinctive -- Cursor uses `oklab()` color space for border colors, applying warm brown at various alpha levels (0.1, 0.2, 0.55) to create borders that feel organic rather than mechanical. The signature border color `oklab(0.263084 -0.00230259 0.0124794 / 0.1)` is not a simple rgba value but a perceptually uniform color that maintains visual consistency across different backgrounds.

**Key Characteristics:**
- CursorGothic with aggressive negative letter-spacing (-2.16px at 72px, -0.72px at 36px) for compressed display headings
- jjannon serif for body text with OpenType `"cswh"` (contextual swash alternates)
- berkeleyMono for code and technical labels
- Warm off-white background (`#f2f1ed`) instead of pure white -- the entire system is warm-shifted
- Primary text color `#26251e` (warm near-black with yellow undertone)
- Accent orange `#f54e00` for brand highlight and links
- oklab-space borders at various alpha levels for perceptually uniform edge treatment
- Pill-shaped elements with extreme radius (33.5M px, effectively full-pill)
- 8px base spacing system with fine-grained sub-8px increments (1.5px, 2px, 2.5px, 3px, 4px, 5px, 6px)

### Do's and Don'ts

- **DO** lean into warm neutrals — `#f2f1ed` canvas, `#26251e` text, `oklab` borders. Pure white or pure black breaks the warm-print atmosphere.
- **DON'T** introduce cold grays (`#e5e7eb`, `#6b7280`) — they fight the warm undertone and feel mechanical against Cursor's literary warmth.
- **DO** apply aggressive negative letter-spacing (-2.16px at 72px, scaling proportionally) on display headlines. Compressed type is the brand voice.
- **DON'T** use default tracking on display sizes — it reads as generic and undersells Cursor's typographic care.
- **DO** use the three-font system deliberately: CursorGothic for display, jjannon serif for body and editorial passages, berkeleyMono for code.
- **DON'T** mix fonts from outside the system — adding a fourth voice fragments the carefully curated typographic palette.
- **DO** use `oklab()` color space for borders and overlays where supported — perceptually uniform colors maintain consistency across backgrounds.
- **DON'T** fall back to flat rgba() borders without considering perceptual contrast on different surface tints.
- **DO** use full-pill buttons (extreme radius) for primary CTAs — they're part of the warm, approachable feel.
- **DON'T** use sharp 2-4px corners on buttons — that aesthetic belongs to engineering brands like NVIDIA, not Cursor's editorial warmth.

## 2. Color Palette & Roles

### Primary
- **Cursor Dark** (`#26251e`): Primary text, headings, dark UI surfaces. A warm near-black with distinct yellow-brown undertone -- the defining color of the system.
- **Cursor Cream** (`#f2f1ed`): Page background, primary surface. Not white but a warm cream that sets the entire warm tone.
- **Cursor Light** (`#e6e5e0`): Secondary surface, button backgrounds, card fills. A slightly warmer, slightly darker cream.
- **Pure White** (`#ffffff`): Used sparingly for maximum contrast elements and specific surface highlights.
- **True Black** (`#000000`): Minimal use, specific code/console contexts.

### Accent
- **Cursor Orange** (`#f54e00`): Brand accent, `--color-accent`. A vibrant red-orange used for primary CTAs, active links, and brand moments. Warm and urgent.
- **Gold** (`#c08532`): Secondary accent, warm gold for premium or highlighted contexts.

### Semantic
- **Error** (`#cf2d56`): `--color-error`. A warm crimson-rose rather than cold red.
- **Success** (`#1f8a65`): `--color-success`. A muted teal-green, warm-shifted.

### Timeline / Feature Colors
- **Thinking** (`#dfa88f`): Warm peach for "thinking" state in AI timeline.
- **Grep** (`#9fc9a2`): Soft sage green for search/grep operations.
- **Read** (`#9fbbe0`): Soft blue for file reading operations.
- **Edit** (`#c0a8dd`): Soft lavender for editing operations.

### Surface Scale
- **Surface 100** (`#f7f7f4`): Lightest button/card surface, barely tinted.
- **Surface 200** (`#f2f1ed`): Primary page background.
- **Surface 300** (`#ebeae5`): Button default background, subtle emphasis.
- **Surface 400** (`#e6e5e0`): Card backgrounds, secondary surfaces.
- **Surface 500** (`#e1e0db`): Tertiary button background, deeper emphasis.

### Border Colors
- **Border Primary** (`oklab(0.263084 -0.00230259 0.0124794 / 0.1)`): Standard border, 10% warm brown in oklab space.
- **Border Medium** (`oklab(0.263084 -0.00230259 0.0124794 / 0.2)`): Emphasized border, 20% warm brown.
- **Border Strong** (`rgba(38, 37, 30, 0.55)`): Strong borders, table rules.
- **Border Solid** (`#26251e`): Full-opacity dark border for maximum contrast.
- **Border Light** (`#f2f1ed`): Light border matching page background.

### Shadows & Depth
- **Card Shadow** (`rgba(0,0,0,0.14) 0px 28px 70px, rgba(0,0,0,0.1) 0px 14px 32px, oklab(0.263084 -0.00230259 0.0124794 / 0.1) 0px 0px 0px 1px`): Heavy elevated card with warm oklab border ring.
- **Ambient Shadow** (`rgba(0,0,0,0.02) 0px 0px 16px, rgba(0,0,0,0.008) 0px 0px 8px`): Subtle ambient glow for floating elements.

## 3. Typography Rules

### Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | CursorGothic | 72px (4.50rem) | 400 | 1.10 (tight) | -2.16px | Maximum compression, hero statements |
| Section Heading | CursorGothic | 36px (2.25rem) | 400 | 1.20 (tight) | -0.72px | Feature sections, CTA headlines |
| Sub-heading | CursorGothic | 26px (1.63rem) | 400 | 1.25 (tight) | -0.325px | Card headings, sub-sections |
| Title Small | CursorGothic | 22px (1.38rem) | 400 | 1.30 (tight) | -0.11px | Smaller titles, list headings |
| Body Serif | jjannon | 19.2px (1.20rem) | 500 | 1.50 | normal | Editorial body with `"cswh"` |
| Body Serif SM | jjannon | 17.28px (1.08rem) | 400 | 1.35 | normal | Standard body text, descriptions |
| Body Sans | CursorGothic | 16px (1.00rem) | 400 | 1.50 | normal/0.08px | UI body text |
| Button Label | CursorGothic | 14px (0.88rem) | 400 | 1.00 (tight) | normal | Primary button text |
| Button Caption | CursorGothic | 14px (0.88rem) | 400 | 1.50 | 0.14px | Secondary button with `"ss09"` |
| Caption | CursorGothic | 11px (0.69rem) | 400-500 | 1.50 | normal | Small captions, metadata |
| System Heading | system-ui | 20px (1.25rem) | 700 | 1.55 | normal | System UI headings |
| System Caption | system-ui | 13px (0.81rem) | 500-600 | 1.33 | normal | System UI labels |
| System Micro | system-ui | 11px (0.69rem) | 500 | 1.27 (tight) | 0.048px | Uppercase micro labels |
| Mono Body | berkeleyMono | 12px (0.75rem) | 400 | 1.67 (relaxed) | normal | Code blocks |
| Mono Small | berkeleyMono | 11px (0.69rem) | 400 | 1.33 | -0.275px | Inline code, terminal |
| Lato Heading | Lato | 16px (1.00rem) | 600 | 1.33 | normal | Lato section headings |
| Lato Caption | Lato | 14px (0.88rem) | 400-600 | 1.33 | normal | Lato captions |
| Lato Micro | Lato | 12px (0.75rem) | 400-600 | 1.27 (tight) | 0.053px | Lato small labels |

### Principles
- **Gothic compression for impact**: CursorGothic at display sizes uses -2.16px letter-spacing at 72px, progressively relaxing: -0.72px at 36px, -0.325px at 26px, -0.11px at 22px, normal at 16px and below. The tracking creates a sense of precision engineering.
- **Serif for soul**: jjannon provides literary warmth. The `"cswh"` feature adds contextual swash alternates that give body text a calligraphic quality.
- **Three typographic voices**: Gothic (display/UI), serif (editorial/body), mono (code/technical). Each serves a distinct communication purpose.
- **Weight restraint**: CursorGothic uses weight 400 almost exclusively, relying on size and tracking for hierarchy rather than weight. System-ui components use 500-700 for functional emphasis.

## 5. Layout Principles

### Spacing System
- Base unit: 8px
- Fine scale: 1.5px, 2px, 2.5px, 3px, 4px, 5px, 6px (sub-8px for micro-adjustments)
- Standard scale: 8px, 10px, 12px, 14px (derived from extraction)
- Extended scale (inferred): 16px, 24px, 32px, 48px, 64px, 96px
- Notable: fine-grained sub-8px increments for precise icon/text alignment

### Grid & Container
- Max content width: approximately 1200px
- Hero: centered single-column with generous top padding (80-120px)
- Feature sections: 2-3 column grids for cards and features
- Full-width sections with warm cream or slightly darker backgrounds
- Sidebar layouts for documentation and settings pages

### Whitespace Philosophy
- **Warm negative space**: The cream background means whitespace has warmth and texture, unlike cold white minimalism. Large empty areas feel cozy rather than clinical.
- **Compressed text, open layout**: Aggressive negative letter-spacing on CursorGothic headlines is balanced by generous surrounding margins. Text is dense; space around it breathes.
- **Section variation**: Alternating surface tones (cream → lighter cream → cream) create subtle section differentiation without harsh boundaries.

### Border Radius Scale
- Micro (1.5px): Fine detail elements
- Small (2px): Inline elements, code spans
- Medium (3px): Small containers, inline badges
- Standard (4px): Cards, images, compact buttons
- Comfortable (8px): Primary buttons, cards, menus
- Featured (10px): Larger containers, featured cards
- Full Pill (33.5M px / 9999px): Pill buttons, tags, badges

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, text blocks |
| Border Ring (Level 1) | `oklab(0.263 / 0.1) 0px 0px 0px 1px` | Standard card/container border (warm oklab) |
| Border Medium (Level 1b) | `oklab(0.263 / 0.2) 0px 0px 0px 1px` | Emphasized borders, active states |
| Ambient (Level 2) | `rgba(0,0,0,0.02) 0px 0px 16px, rgba(0,0,0,0.008) 0px 0px 8px` | Floating elements, subtle glow |
| Elevated Card (Level 3) | `rgba(0,0,0,0.14) 0px 28px 70px, rgba(0,0,0,0.1) 0px 14px 32px, oklab ring` | Modals, popovers, elevated cards |
| Focus | `rgba(0,0,0,0.1) 0px 4px 12px` on button focus | Interactive focus feedback |

**Shadow Philosophy**: Cursor's depth system is built around two ideas. First, borders use perceptually uniform oklab color space rather than rgba, ensuring warm brown borders look consistent across different background tones. Second, elevation shadows use dramatically large blur values (28px, 70px) with moderate opacity (0.14, 0.1), creating a diffused, atmospheric lift rather than hard-edged drop shadows. Cards don't feel like they float above the page -- they feel like the page has gently opened a space for them.

### Decorative Depth
- Warm cream surface variations create subtle tonal depth without shadows
- oklab borders at 10% and 20% create a spectrum of edge definition
- No harsh divider lines -- section separation through background tone shifts and spacing

## 7. Interaction & Motion

### Hover States
- Buttons: text color shifts to `--color-error` (`#cf2d56`) on hover -- a distinctive warm crimson that signals interactivity
- Links: color shift to accent orange (`#f54e00`) or underline decoration with `rgba(38, 37, 30, 0.4)`
- Cards: shadow intensification on hover (ambient → elevated)

### Focus States
- Shadow-based focus: `rgba(0,0,0,0.1) 0px 4px 12px` for depth-based focus indication
- Border focus: `oklab(0.263 / 0.2)` (20% border) for input/form focus
- Consistent warm tone in all focus states -- no cold blue focus rings

### Transitions
- Color transitions: 150ms ease for text/background color changes
- Shadow transitions: 200ms ease for elevation changes
- Transform: subtle scale or translate for interactive feedback

## 8. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <600px | Single column, reduced padding, stacked navigation |
| Tablet Small | 600-768px | 2-column grids begin |
| Tablet | 768-900px | Expanded card grids, sidebar appears |
| Desktop Small | 900-1279px | Full layout forming |
| Desktop | >1279px | Full layout, maximum content width |

### Touch Targets
- Buttons use comfortable padding (6px-14px vertical, 8px-14px horizontal)
- Pill buttons maintain tap-friendly sizing with 3px-10px padding
- Navigation links at 14px with adequate spacing for touch

### Collapsing Strategy
- Hero: 72px CursorGothic → 36px → 26px on smaller screens, maintaining proportional letter-spacing
- Navigation: horizontal links → hamburger menu on mobile
- Feature cards: 3-column → 2-column → single column stacked
- Code editor screenshots: maintain aspect ratio, may shrink with border treatment preserved
- Timeline visualization: horizontal → vertical stacking
- Section spacing: 80px+ → 48px → 32px on mobile

### Image Behavior
- Editor screenshots maintain warm border treatment at all sizes
- AI timeline adapts from horizontal to vertical layout
- Product screenshots use responsive images with consistent border radius
- Full-width hero images scale proportionally

### Iteration Guide
1. Always use warm tones -- `#f2f1ed` background, `#26251e` text, never pure white/black for primary surfaces
2. Letter-spacing scales with font size for CursorGothic: -2.16px at 72px, -0.72px at 36px, -0.325px at 26px, normal at 16px
3. Use `rgba(38, 37, 30, alpha)` as a CSS-compatible fallback for oklab borders
4. Three fonts, three voices: CursorGothic (display/UI), jjannon (editorial), berkeleyMono (code)
5. Pill shapes (9999px radius) for tags and filters; 8px radius for primary buttons and cards
6. Hover states use `#cf2d56` text color -- the warm crimson shift is a signature interaction
7. Shadows use large blur values (28px, 70px) for diffused atmospheric depth
8. The sub-8px spacing scale (1.5, 2, 2.5, 3, 4, 5, 6px) is critical for icon/text micro-alignment

## 10. Voice & Tone

Cursor's voice is **engineer-poetic** — straightforward technical claims dressed in warm typographic restraint. Marketing copy emphasizes the developer experience over capability lists: "the best way to code with AI" (homepage 2026-05) is short, confident, present-tense. Surfaces use ivory-warm palette + crimson hover (`#cf2d56`) — the warmth signals "this is a tool you live in for 8 hours/day, not a flashy consumer demo."

| Context | Tone |
|---|---|
| CTA | Plain. "Download for macOS", "Get started", "Request a demo" |
| Marketing | Single-claim hero, screenshots dominate |
| Documentation | Concise; assumes IDE / engineering context |
| Error (model) | Specific. "Claude rate limit reached. Switch model or wait." |

**Voice samples**
- Marketing CTA (KR): *"macOS용 다운로드"* <!-- verified: cursor.com/ko homepage 2026-05 -->

**Forbidden phrases.** "10× developer", "AI-powered" without specificity. Aggressive comparison-mode marketing.

## 11. Brand Narrative

Cursor (corporate name **Anysphere, Inc.**) was incorporated **2022** by four MIT students — **Michael Truell (CEO)**, **Sualeh Asif (CPO)**, **Aman Sanger (COO)**, and **Arvid Lunnemark (former CTO)** ([Anysphere — Wikipedia](https://en.wikipedia.org/wiki/Anysphere)). The team **graduated from OpenAI's accelerator** and **launched Cursor publicly March 2023** as a fork of VS Code with first-class LLM integration. Founding observation: AI-assisted coding was being bolted onto editors as plugins, but the editor itself needed redesign for AI-native workflows. Funding trajectory has been one of the steepest in software history: **$8M seed (Oct 2023)** led by **OpenAI Startup Fund** with **Nat Friedman** + **Arash Ferdowsi** angels → **$60M Series A (Aug 2024)** → **$900M Series C (Jun 2025)** led by **Thrive Capital** at **$9.9B** → **$2.3B Series D (Nov 2025)** co-led by **Accel** + **Coatue** with **Google** + **Nvidia** strategic, valuing the company at **$29.3B** ([Inc — Cursor billionaires](https://www.inc.com/ben-sherry/this-ai-coding-startup-just-minted-4-new-billionaires/91265014), [Contrary Research — Cursor breakdown](https://research.contrary.com/company/cursor)). ARR crossed **$100M January 2025**, **$500M June 2025**, **$1B+ annualized post-Series D**. What Cursor refuses: aggressive comparison-mode marketing, "10× developer" framing, AI-magic vocabulary that obscures the actual editor mechanic.

## 12. Principles

1. **The editor is the brand.** *UI implication:* marketing screenshots are always the actual editor; never illustration.
2. **Warm ivory, not cold black.** *UI implication:* default canvas warm `#f7f7f4`; dark theme uses warm grays not pure black.
3. **Crimson hover signals interaction.** `#cf2d56` text shift on links. *UI implication:* never use crimson as default chrome color.
4. **Shadow blur is large.** 28px / 70px blurs create atmospheric depth. *UI implication:* don't use tight shadows; the diffused atmospheric quality IS the brand.
5. **Typography micro-alignment matters.** Sub-8px spacing scale (1.5/2/2.5/3) for icon-text alignment. *UI implication:* don't round to 4px increments; the 1.5px granularity is intentional.

## 13. Personas

*Personas are fictional archetypes informed by Cursor user segments (full-time engineers using AI pair-programming, indie developers, ML researchers), not individual people.*

**Sarah Lin, 33, Seattle.** Senior backend engineer. Cursor as primary IDE for 6 months. Uses tab autocomplete + Cmd+K refactoring + Composer for multi-file changes.

**Henrik Sondergaard, 41, Copenhagen.** Indie developer building SaaS. Multi-file Composer is the workflow that justifies the subscription.

**Ravi Krishnan, 28, Bengaluru.** ML researcher. Uses Cursor for Python notebooks + research code. Cares about Claude/GPT model selection + cost transparency.

## 14. States

| State | Treatment |
|---|---|
| **Empty (welcome)** | Centered "Open folder" CTA + recent projects |
| **Empty (no AI history)** | "Try Cmd+K to get started" with keyboard shortcut hint |
| **Loading (model thinking)** | Inline cursor-blink (1.5px width, crimson) where model is composing |
| **Loading (file applying changes)** | Diff view with applying state, accept/reject buttons |
| **Error (model)** | Inline below input. "Claude rate limit reached. Switch model or wait." |
| **Error (apply failed)** | Diff stays visible, error tooltip with specific reason |
| **Success (changes applied)** | Soft cream pulse on file tabs, no toast |
| **Success (Composer commit)** | Multi-file diff folds into success summary |
| **Skeleton (welcome cards)** | Warm-cream rectangles, no shimmer |
| **Disabled (no model selected)** | 0.5 opacity + crimson "Select a model" link |
| **Loading (long agent run)** | Persistent progress with step trace, cancellable |

## 15. Motion & Easing

| Token | Value | Use |
|---|---|---|
| `motion-instant` | 0ms | Cursor commit |
| `motion-fast` | 150ms | Hover crimson shift |
| `motion-blink` | 530ms | Cursor blink (model composing) |
| `motion-standard` | 250ms | Modal, panel |

Easings: standard cubic-bezier. **Crimson hover** is the only color animation. `prefers-reduced-motion: reduce` disables blink (steady cursor).
