Do I need Claude Code CLI installed to run this?

I'm a bit confused about what subscription/service I need to run this. Do I need Code Code CLI installed? Do I need a Claude subscription? I have a Google AI Pro subscription through Google One. Can I use that? I also have a ChatGPT Plus subscription and a Perplexity subscription. Which would be best? I am not sure about API-type access as that's a separate paying model/service usually.
