When you ask an AI in the browser to "make me a web page", it hands you a big block of code, and then you have to copy it, create a file, paste it in, open the browser... one wrong step and you're stuck.

Claude Code is different. It runs in the terminal on your computer. You say "make me a web page" and it creates the file itself, writes the code into it itself, runs and tests it itself, then tells you "open index.html in your browser to see it".
