Have you ever purchased paid plans of AI tools?

There are many AI companies that offer tools for free. However, it is said that those free AI tools are not that accurate. This might be true to some extent. Paid AI tools seem to perform much better as compared to free tools. They offer comprehensive answers and flexible solutions to problems faced by users. So, have you ever purchased a paid plan? I certainly do plan to purchase paid version in case if I ever need to do so.
