How I Built an AI-Powered Website Modernizer in 3 Days with Kiro

Ever feel like some websites are stuck in the digital Stone Age? That’s what sparked the creation of ReVitalize, an AI-powered platform that modernizes outdated websites in a flash. Built in just three days using Kiro, a context-aware AI coding tool, this project highlights how AI is changing the game. What used to be a multi-week endeavor of planning, spec writing, and feature-by-feature construction was compressed into a single weekend project. The key? Conversational development with an AI that remembers the project's context.

The secret sauce is Kiro's ability to maintain context throughout the development process. Unlike traditional AI coding tools that require constant re-explanation, Kiro remembers previous conversations, the project's structure, design decisions, and code patterns. For instance, when asked to "add example sites with auto-fill," Kiro intelligently updated the relevant React components like `URLInputForm` and `TransformationWorkspace` without needing explicit instructions. Beyond context, Kiro also shines with intelligent problem-solving. When encountering a token limit error with GPT-4 Turbo, Kiro didn't just fix the error; it analyzed the OpenAI pricing table and suggested switching to the more efficient GPT-4o Mini, showcasing its ability to optimize the entire approach. The developer even used "vibe coding", using natural language requests like "Make UI much better than this reference website" instead of detailed specs, which resulted in 500+ lines of beautiful code in minutes.

ReVitalize boasts a complete Next.js 14 project structure, API routes for scraping and transformation, React components, and AI integrations with OpenAI and Google Gemini. The project leverages "steering documents" and a `spec.yaml` file to maintain consistent AI outputs and a clear architecture. The result is a platform with instant website transformation, side-by-side comparison, chat refinement, component extraction, accessibility auditing, and export to ZIP/GitHub. For developers looking to streamline their workflow and unlock the potential of AI-assisted development, ReVitalize serves as a compelling example of what's possible with tools like Kiro.
