Modern search engines like Google use AI, and they have been using AI long before LLMs like ChatGPT were widely available.
Mori is a walking encyclopedia+ she can be used for automating tasks. But her knowledge is all truths and facts; she isn't trained to analyze/find patterns, and she cannot hallucinate and give you wrong answers.
She is not artificially mimicking human intelligence, but you can use her like you would an LLM, Siri or a robot and achieve better results.
So the "more than AI" part is correct. It's like AI without the A

Mori is like a living AI, you got questions she got answers plus shes adorable.
