AI Chatbot App UI Template

Lumen is an AI chatbot app UI template built on an "Ambient Aurora Intelligence" look: a near-black charcoal canvas, warm graphite surfaces for raised cards, and a living violet-to-teal aurora gradient reserved for the AI avatar, the send action, and active states. AI replies arrive as borderless tonal blocks with a thin aurora seam down the left edge, while user messages stay compact slate pills, so you always know who spoke at a glance.

The template ships six connected screens that form a complete assistant flow: a Home greeting with prompt-starter cards and recent threads, an active Chat with a long itinerary reply and a glowing composer, a Personas screen of switchable assistant modes, a searchable Library of past chats, a full-screen Voice mode with a breathing aurora orb and live transcript, and a Settings screen with model selector, tone slider, and connected apps. Together they cover the real journey of a conversational AI product, from first prompt to voice reply.

Use it in Sleek and make it your own: restyle the aurora palette, edit any screen with AI by describing the change, and add the flows your product needs. Then export it to code, copy it into Figma with no plugin, or hand a prompt to an AI agent to build it for real, all far faster than starting from a blank canvas.
