Otter — Design System

light · modern · medium · custom · confidence 92% · deep decode

Otter transcribes in Circular at a light 58px/300, electric blue #144FFF for the emphasis words, and a dense 14-17px body befitting meeting notes. Transcript UI with speaker chips and live summaries anchors every section — an AI notetaker whose page reads at the same tempo as the conversations it captures.

Tokens

Otter's decoded design system: background #FFFFFF, text #000000, accent #1D25E2, link #1D25E2, primary #144FFF; type scale h1 60px / h2 56px / body 12px; 4px spacing base; 16px base radius. The single interactive/action color is #1D25E2 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Otter — Design System

> light, modern, medium, custom — deep decode (measured live)

Otter transcribes in Circular at a light 58px/300, electric blue #144FFF for the emphasis words, and a dense 14-17px body befitting meeting notes. Transcript UI with speaker chips and live summaries anchors every section — an AI notetaker whose page reads at the same tempo as the conversations it captures.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#144FFF` |
| accent | `#1D25E2` |
| link | `#1D25E2` |
| secondary | `#5A5DA3` |
| button_bg | `#1D25E2` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#1D25E2` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link`, `button_bg` are all `#1D25E2` — one role, not several (your action color).
- **accent** `#1D25E2` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#144FFF` — a brand color — but the call-to-action uses #1D25E2, not this.
- **secondary** `#5A5DA3` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 92.1% · `#DFE1E4` 2% · `#4C6A6F` 2% · `#B9B9BB` 1.7%

## Typography

- Heading: **Circular** _(free fallback: Manrope)_
- Body: **Circular** _(free fallback: Manrope)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 58px / 300 · lh 64px · tracking -1.17px |
| h2 | 55px / 300 · lh 60px · tracking -1.09px |
| h3 | 47px / 300 · lh 56px · tracking -0.47px |
| body | 16px / 400 · lh 23px |
| small | 14px / 400 · lh 19px |

- Weight ladder: 300 · 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Circular is proprietary — closest free match: Manrope (Google). Load Manrope; keep Circular first so licensed users still get it.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 14px, 16px, 19px, 23px, 31px, 35px, 39px — snap all gaps/padding to these
- section rhythm: 97px top/bottom padding per section (measured)

## Radius
- base: 16px
- button: 0px
- card: 16px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#346E4A` / `#FFFFFF` | 1px solid rgb(52, 110, 74) | 2px | 12px 10px 12px 10px | 600 13.008px / 0.13008px | none |
| secondary | `rgba(29, 37, 226, 0)` / `#000000` | none | 9.74708px | 3.89883px 7.79767px 3.89883px 7.79767px | 400 15.5953px | none |

**States (measured, not guessed)**

- primary focus: outline `1px solid rgb(0, 0, 0)`
- secondary hover: background `rgba(29, 37, 226, 0.05)` · color `#1C24DE`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 0px 18px 0px`

## Motion
- durations: 300ms (dominant) · 450ms · 350ms
- easings: `cubic-bezier(0.215, 0.61, 0.355, 1)` (dominant) · `ease`
- animated properties: color, background-color, opacity, transform

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Layout (measured)
- nav: 80px sticky · backdrop blur(8px) · bg rgba(255, 255, 255, 0.94)

## Motion choreography (measured)
Load order: `div.swiper-dot` @0ms → `div.otFlat` @629ms → `span.swiper-dot`×2 @863ms → `div.swiper-slide`×8 @5844ms → `span.swiper-dot`×2 @5844ms → `div.slider-dot-agent`×2 @5861ms
- scroll reveal: 5 elements rest at opacity 0, translateY(-32px), animate in over 450ms (2 revealed during the drive).

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- card ×4: pad 0px 0px 0px 0px · r 31.1907px · bg rgba(0, 0, 0, 0)
  - hover: font-weight `400` · letter-spacing `-0.46786px`

## Responsive (measured)
- breakpoints: 426px · 479px · 550px · 600px · 768px · 896px
- mobile (390px): hero 42px · body 20px · nav: hamburger

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
