Building With AI — and Fixing What It Breaks

AI changed how software gets built and what it costs to build. It also created a new kind of problem: a prototype from Lovable, Bolt, v0 or Replit that looks finished, demos beautifully, and then comes apart the moment real users, real data, or a real payment flow touch it. These guides cover both halves. What AI coding tools are genuinely good at, where the wall usually shows up, and what it takes to turn a generated prototype into software you can run a business on — auth, data models, permissions, error handling, deploys, the unglamorous parts that decide whether it survives. If you built something yourself and got stuck, start here. Knowing which part is salvageable is usually worth more than starting over.
