I need a single-page web application that feels as light as it looks: a black-and-white, neutral, and minimalistic interface that houses a powerful AI assistant. Its main priority is problem-solving, and I expect it to tackle any kind of request—from code debugging and mathematical calculations to image generation, content writing, and general queries—without shifting the aesthetic or over-complicating the user flow. Core capabilities I want available from the same prompt box: • Professional image generation for thumbnails, logos, banners, and other designs • Complete, working HTML / CSS / JavaScript snippets on demand • Accurate mathematical, financial, and statistical calculations • Polished written content, analyses, and documents • A persistent conversation history shown in a collapsible side panel Interface requirements: • Pure black-and-white palette, no additional colors • Ultra-clean layout with plenty of negative space • Rounded input field anchored at the bottom, modern look • Elegant chat bubbles that keep responses readable at a glance • Fully responsive so it feels native on both mobile and desktop The sidebar should display every past exchange so users can reopen or rename a conversation later. No clutter, no extra icons—just the essentials that let the assistant focus on solving problems of “all kinds.” Deliverable: A deploy-ready HTML/CSS/JS project (vanilla or a lightweight framework if that speeds development) that embodies the design above and routes every user prompt to a placeholder API endpoint so I can hook up my own model later. If this aligns with your skill set, let’s talk implementation details and timelines.
