Julius design specAI Products

A calm, app-first AI workspace where the landing page IS the product — like Bolt.new there is no marketing hero at all, just a persistent 48px left icon rail and a centred composer asking "What can I do for you today?". The canvas is a near-white #fafafa and the ink is a WARM-NEUTRAL #404040 that never hardens to black, with #737373 and #545454 beneath it. Inter is the only family on the page and it is used small: the display is a modest 30/36 at weight 500, and the single piece of weight-700 text anywhere is the 24px blue wordmark. Every size carries slight NEGATIVE tracking, from -0.14px at 14px through -1.2px at 24px, including 12px labels — the inverse of the usual convention of opening tracking at small sizes. One blue #2563eb does all the interactive work, covering the wordmark, the Sign Up fill and the circular send arrow, while every other control is a transparent 9999px capability pill (Browser Agent, Video, Excel, Slides) whose 1px hairline turns blue-tinted rgba(37,99,235,.25) when active. Depth is nearly absent: eleven of the twelve recorded shadows are transparent placeholders, leaving exactly one real multi-layer shadow on the white 12px composer, and there is exactly ONE gradient on the whole page, a faint blue wash behind the announcement pill, with no imagery, canvas or video anywhere.

Captured from the live site's computed styles into a prompt-ready DESIGN.md you can paste into Cursor, v0, Lovable, Bolt or Claude Code. Below is a summary of each captured surface.

Marketing site

Source: julius.ai (live DOM, computed styles), 2026-07-27 (desktop 1512px). Coverage: home page. Full product is behind login (needs-dashboard). 0 stylesheets blocked. Note: the page hydrates late — a first extraction returned zero type roles because text had not painted; values below come from a re-run after render. Reality check: hint ("clean light, chart-dense") is half right, and the product has repositioned. Clean light is correct — canvas #fafafa, ink #404040, a single Inter family, one blue #2563eb. But "chart-dense" is wrong for the landing surface: Julius now sells itself as "Excel, Slides, Tasks with AI" and, like Bolt.new, has no marketing hero at all — it opens straight onto the product composer ("What can I do for you today?") with a persistent left icon rail. The signature the hint misses: ink is warm-neutral #404040, never black, and the display is deliberately SMALL at 30/36 weight 500 — the largest text on the page — while the heaviest text is the 24px/700 wordmark, which is also the only blue text.

Visual Theme & Atmosphere

A quiet, app-first AI workspace — the landing page *is* the product, so there is no hero, no marketing photography and almost no chrome. Everything sits on a near-white #fafafa field with a warm-neutral #404040 ink that never hardens to black, and the entire interface is one Inter family at small sizes. A single blue carries the wordmark, the Sign Up button and the send arrow; every other control is a transparent pill or a 6px ghost button. Depth is almost absent — one soft composer shadow and a blur(24px) — so the composer reads as the only object on the page. Feels: calm, light, app-first, unfussy.

Rule: one blue does everything interactive; all other controls are transparent pills with neutral or blue-tinted 1px hairlines. Ink stays #404040, never #000000.

Patterns: everything carries slight NEGATIVE tracking (-0.14px at 14 up to -1.2px at 24), including small text — the opposite of the usual open-at-small-sizes convention. The display is small (30px) and mid-weight (500); the only weight-700 text on the page is the wordmark.
