Cover image for What happens after someone asks
What happens after someone asks your business, “Can you help with my project?” I designed this AI lead qualification concept to show how an interior design studio could turn a website conversation into an organized enquiry, ready for its team to review. The experience brings together: • A conversational assistant that collects project requirements. • Structured details including location, budget, style, and timeline. • A dashboard that gives the owner a clear enquiry summary. • An AI-drafted response with human approval. The goal: give potential customers a welcoming first interaction and give the business a clearer starting point for follow-up. This animated showcase explores the product’s UI/UX and intended workflow using GSAP and HyperFrames. Created by Kazi Eajaj Hossain · Concept demo with fictional data. Have a repetitive enquiry or customer support workflow? Let’s discuss how a custom AI assistant could fit your business. #AIAgents #AI Automation #ConversationalAI #UIDesign #WorkflowAutomation
