There are better options out there
This is one of many Chat GPT like aggregators. I have bought lifetime access through a lifetime aggregator. Activation instructions were lacking somewhat, but in the end, I managed to activate the purchase. That said, the description of what was included did not match what I got in the end and included some misleading information. It took a couple of weeks and intervention from the aggregator to get that stringent out (well, almost, as it still does not exactly match the description). The way it was resolved was for the vendor to change the terms of the lifetime offer to match the aggregator description. This was a change for everyone, I assume, but there was no communication about it at all. The vendor was not responsive to help tickets opened on their website or to e-mail communication. The models provided are extremely limited and mostly limited to the very cheap models. Some of the pre-built chat models that I should have access to are not working as well.
The interface is intuitive and well-built. That said, when I dove deeper, it seems that there are many other companies (or are they the same?) that provide the same interface, so I'm not sure what is really going on.
As the models provided are limited, other services provide better value for money (esp. considering how cheap it would be to run those models on a pay-as-you-go basis). Together with the lack of any meaningful communication or support, I cannot recommend this service. As I have a lifetime subscription, I will use it when it makes sense, as it is now "free" (or sunk-cost).
