About This Guide

Most AI tutorials stop at a simple chatbot. Real-world applications are messier. They require state management, undo/redo functionality, rate limiting, and graceful degradation when APIs fail.

This ebook condenses 2 years of production experience building AI tools at DIAITI. We strip away the hype and focus on the engineering patterns that actually work in production environments.

Includes: Full source code for a demo SaaS application built with Next.js 14, Tailwind, and OpenAI API.
