I’m a programming enthusiast, and I’ve built plenty of websites, most of them using WordPress.
I wasn’t fully satisfied with some WordPress themes, so I used Codex to modify them. I not only tweaked lots of styles but also added plenty of new features, and the code works perfectly after the changes.
Codex is an incredibly powerful AI coding tool. When it updated to GPT-5.3-Codex, it wasn’t very good—actually worse than version 5.2—but once it hit 5.4, it became incredibly useful.
I also used it to upgrade an old website written in PHP5, making the code much more secure and powerful.
Basically, whatever idea I have, I just tell Codex, and it writes the functionality really well. All I need to do is adjust some CSS styling.
I’ve heard Claude Code is another extremely powerful AI coding tool—even better than ChatGPT Codex—but I haven’t tried it yet. I’ll give it a shot when I get the chance.
