OpusClip design specAI Products

A pure-black consumer-AI-video marketing page whose discipline is the story: the canvas is #000000 and nearly everything on the hero is white Geist type and one white pill CTA, so the surface reads as strict high-contrast monochrome even though a large colourful token system sits underneath it. The brand palette — opus-purple #6723ff, sweet-purple #a259ff, candy-blue #72ffff, light-blue #00d7ff and a playful yellow #ffd02f — is rationed almost entirely to Rive-animated illustration, badges and demo art, and never once fills a button or nav item, which stay white-on-black or half-alpha-white ghost. The signature hero move is a large 100px-radius pill INPUT (“Drop a video link”, h68, bg #2d2d2d, placeholder #e2e3e7) as the primary action, paired with a white “Get free clips” button that darkens to #e0e0e0 on hover, above rounded video-clip demo cards that auto-scroll in 20–40s linear marquees. Type is a single Geist Variable family: a 60px display at weight 600 and -1.8px tracking, 24px sub-heads, 14–16px body, with muted nav and body set in rgba(255,255,255,.5) rather than a separate gray. Depth is refused — there are NO box-shadows anywhere; separation comes purely from #171718 and #191919 surface steps over black and a dominant 1px rgba(255,255,255,.25) hairline, with radii running 8px controls, 16–20px cards and full 100px pills. Motion is a 0.2s ease house transition on opacity, background, colour and transform with an expo cubic-bezier(0.19,1,0.22,1), driven by GSAP and Rive, and it deliberately does not honour reduced motion. The captured timeline/editor lives in the app behind sign-in; the marketing surface itself is a clean dark product page, not an editor.

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: opus.pro (live DOM, computed styles), 2026-07-29 (desktop 1512px). Webflow-built (cdn.prod.website-files.com), Geist Variable webfont. Coverage: public marketing homepage. Editor/app (the actual clip timeline) is behind sign-in, needs-dashboard. 2 stylesheets were cross-origin (sheetsBlocked 2) — hover/focus captured from same-origin Webflow sheets only. Reality check: hint said "timeline/editor-forward, Descript the only neighbour". The timeline lives in the app, not this marketing page — the homepage is a conventional-but-clean pure-black AI-product page (Geist, white pill CTAs, rounded video-demo cards, logo marquees). What is genuinely distinctive: a large pill-shaped URL-drop input as the primary hero action, and a colourful Rive-animated brand system (opus-purple #6723ff + candy blue + yellow) held almost entirely OFF the monochrome hero and reserved for illustration.

Visual Theme & Atmosphere

Confident, pure-black consumer-AI-tool marketing. The canvas is #000000; nearly everything on the hero is white Geist type and one white pill CTA, so the surface reads as high-contrast monochrome despite a large colourful token system underneath. Colour (opus purple, candy blue, playful yellow) is rationed to Rive-animated illustration, badges and demo canvases — never to the chrome. The recognisable hero move is a big rounded pill input ("Drop a video link") paired with a white "Get free clips" button, sitting above rounded video-clip demo cards that auto-scroll in marquees. Structure comes from low-alpha white hairlines, not shadows (there are none). Feels: dark, crisp, product-first, high-contrast.
