AI Product — Voice AI Landing
A calm, futuristic one-page marketing site for a fictional voice AI product, built in vanilla HTML, CSS and JS. It pairs a deep indigo palette with pastel waveform accents, an animated hero orb, and a press-to-talk demo. Sections cover assistants, dubbing and accessibility use cases, a play-to-hear voices showcase with a live reacting waveform, a three-step API walkthrough, monthly and annual pricing, testimonials, an email capture CTA, and a footer.

</html>Voice AI Landing
A full single-page landing for Vox, a fictional realtime neural-voice product. The design leans into a deep indigo and navy backdrop lit with soft pastel waveform accents — calm, futuristic, and human. A sticky glass nav sits over a hero that features an animated floating orb, a canvas waveform, and a “press to talk” button that flips the orb into a live, glowing listening state with rolling captions delivered through a toast helper.
Below the hero, a social-proof logo strip leads into three use-case cards (voice assistants, dubbing and media, accessibility), then a voices showcase where each voice pill retunes the live canvas waveform’s color and speed and the play button animates a sample reading. A three-step “how it works” walkthrough shows code snippets, followed by a pricing block with a monthly/annual toggle that rewrites the numbers, customer testimonials, an email-capture CTA, and a footer.
Everything is vanilla — no frameworks or build step. The waveforms are drawn on <canvas> with
requestAnimationFrame, interactions use a single IntersectionObserver for scroll reveals, and the
layout is fully responsive down to ~360px with a mobile menu toggle. Motion is disabled under
prefers-reduced-motion.
Illustrative UI only — fictional brand, not a real product.
