7. Signature Design Concept

The landing page will feature an interactive "Vernacular Voice Journey" animation. Users will see a dynamic map of India, with voice waves emanating from different regions, representing the diverse vernacular languages supported by the CRM. As users hover over each region, a pop-up will display a sample voice interaction in the local language. This concept will be built using motion/react for smooth transitions and interactions.

Landing Hero Motion Brief

The hero section will depict a microphone icon that transforms into a chatbot interface as the user scrolls. The animation will show voice inputs being processed into actionable insights, symbolizing the CRM's capability to convert vernacular speech into business outcomes. The loop will last 10 seconds, with interactive elements allowing users to click and explore different language capabilities.
