Elva is a voice-first AI video editor for mobile — a fully agentic product that turns raw camera-roll footage into social-ready clips with no manual editing. Users speak a request, and Elva selects scenes, cuts to rhythm, scores to a mood, and delivers a finished video. The full design system shipped as one connected launch: brand identity, AI persona, UX, UI, onboarding, monetization, App Store creatives. The brand is content-first — black, white, and glass, with a chromatic-aberration palette borrowed from whatever the user films. Elva's persona is a transparent glass blob with 30+ behavioral states: she listens, thinks, flirts, celebrates, and nudges — full personality without a face. A FOMO-driven quiz converts installs into active users. An intelligent camera layers real-time coaching over the viewfinder so raw footage starts strong. A context-aware storefront surfaces premium features at the exact moment they add value, alongside free alternatives.
