We live in an era of human-machine collaboration. Artificial intelligence tools are increasingly becoming an extension of your tastes, habits, and even your DNA. Yesterday I read some articles comparing Codex and Claude Code; people praised Claude's emotional resonance. However, my friends and I felt that Codex was more intuitive in actual use. Today, I switched from the Perplexity browser, which I'd used for five months, to Claude in Chrome, and my work efficiency has significantly improved. Ultimately, there is no "best AI," only the AI best suited to you.
