404 Page Generator
A focused tool for building 404 error pages that actually help users recover instead of just displaying "page not found." It checks your project context for brand voice and site structure, then walks you through messaging, navigation options, conversion opportunities, and technical considerations like proper HTTP status codes and analytics tracking. The framework is solid: it pushes you toward empathetic copy, suggests linking to popular pages and search, and reminds you to maintain consistent branding so users know they haven't left your site. Use this when you're setting up error handling or auditing why your 404s have high bounce rates. The emphasis on turning a frustrating moment into a recovery opportunity is the right mindset for production sites.
