3 questions:

It is unclear to me what the AI part is doing. The video explains how you use templates, and how a variable is pasted in the body of a page, but how is GPT-4 involved into this?

When the price of GPT-4o changes again, will you also increase the credit limit? Or only decrease when GPT-5 would be more expensive.

Does your platform also send the emails, or do I need to export them to send them with a different application?
