Maybe 1.5 stars. I was bombarded with ads for Liner as a research assistant. It is supposed to provide accurate and real references along with useful answers. Answers I got were simply wrong, mixing up simple geography and thereby give nonsense answers. Follow-up clarifications didn't get good results either. Another con was Liner's inability to understand the difference between "history" and "histories," resulting in totally incorrect answers. Follow-ups brought no corrections in Liner's answers. A few references were mildly of interest, but they were formatted in a way that made it slow and hard to access them.
