🚀 Why Nexus AI?

Most chatbots feel utilitarian. Nexus AI feels like a tool you want to use. We've focused on creating a "Product-Grade" experience that rivals top SaaS applications.

• ✨ Immersive Design: A deep, reliable dark mode with glassmorphism accents and distraction-free typography (Inter).
• ⚡ Smart Auto-Titling: The app reads your first prompt and automatically generates a concise, relevant title for the chat session using AI. No more "New Chat 1".
• 📝 Developer-First Markdown: Pristine syntax highlighting for code blocks (Prism.js), tables, and formatted text.
• 🔒 Secure & Private: Robust JWT authentication ensures your conversation history remains yours.
• 📱 Fluid Responsiveness: A seamless experience whether you're on a desktop workstation or a mobile device.
