The difference is easy, a ChatBot take informacion from a knowledge base scrapped from several previos inputs. Because of this much information isn't in this base and in this case a ChatBot beginn to invent the answers using everything in its base. More if it is made by big companies which use it mainly as tool to obtain user datas and reliability only in second place. AI can be usefull in profesional use in research science, medicine, physic, etc. with specializied LLM, but as general chat for a normal user its a scam. It's a wrong approach to AI in the general use, the Google AI proved it.

I use an AI as main search (Andisearch) because it is made as search assistant, not as ChatBot. In its base is only enough information to "understand" your question and search the concept in reliable sources in real time from the web. Because of this it's accuracy is way better than those from every ChatBot from Google, M$ or others. It don't invent nothing, if it don't know the answer, offers a normal web search, apart it's one of the most private search, anonymous, no logs, no tracking, no cookies, random proxie and Videos in the search result sandboxed. Not very known, despite it was the first one using AI, long before the others, from a small startup with 2 Devs, I use it since almost 2 years. Until now I found nothing better or more usefull for the daily use with AI https://andisearch.com/ PP
