What to know first
Look first at Claude Pro if you mainly write code, need long context, or want to save with annual billing. Look first at Plus if you want Codex models such as GPT-6.1 Terra and Sol in the same subscription, or rely on ChatGPT's Excel, Word, and PowerPoint integrations. Both let you pay as you go after hitting a limit instead of upgrading right away. On the App Store, most regions price the two closely, but the gap is large in places such as the Philippines and Brazil, so check AISub's price pages before subscribing.
