Searchie Wisdom AI - is it poor value?

WisdomAI is great addition for Searchie but I need to question it's value. If I understand correctly, the plan advertised at the moment for Seachie Wisdom AI allows for 100 questions to be asked by my customers ($49 per month) If I have one customer, they can ask one hundred questions in a one month period. But if I promote this service to 50 customers, they'll get to ask JUST TWO questions each...in a one month period, before that limit is reached. So am I reading this right, or is it 100 messages allowed for EACH customer that I am serving using Searchie? Otherwise it looks like each message/question to WisdomAI costs $0.50 which seems poor value, especially when I know I can hop onto open AI's ChatGPT 3 for as many times as I like....for free. It's not the same service, but it's a stark contrast nonetheless. Imagine being charged by Google $0.50 each time you do a search. I realise ChatGPT 4 is being used for this service, which OpenAI charges $20 a month for one customer, so the costs of this newer technology are still high. But still, unless I've read the value of what I am receiving for the price wrong for Wisdom AI, I can't recommend this to my customers, since the 100 message limit could be reached in just minutes. Another concern is that on the Searchie Wisdom AI site (https://wisdomai.com/) it mentions "Additional message fees may apply" but this isn't transparent - there's simply no information on this. What are the additional fees?
