Meanwhile, I just setup codex for the first time (to try Astra) and it offered to load my Claude and Cursor conversations and claims to even do it in a way where it says in sync if you use both. The only reason to use Claude Code is the 20x usage of the 200$ plan is ridiculous value if you have the need for that volume.
“Offered to load conversations”. Let me translate that. “Can we please upload your data to our servers showing how you work with other AI agents?”
The 20x plan offers the same amount of monthly usage per dollar as the $100 plan. It offers 2x monthly usage of the $100 plan. It's incredibly deceptively named, the "20x" is only about the 5-hour window.
