I use Codex regularly for building frontend pages and creating content for marketing. It’s been a helpful tool for both, saving me time and making it easier to turn ideas into finished work.

I've had a very good experience with OpenAI Codex. I use Claude Code as well, and I've been happy with both. Codex is an AI coding assistant I'd recommend to other developers, and it gets full marks from me.
