Question about the internet and place of study

I finished seminary and, as part of my efforts to build a Torah home, I studied in the tax consulting track. There are 4 exams that must be passed in order to become a tax consultant. Unfortunately, I did not pass 2 of them. At the moment I am not working so that I can complete the exams. The truth is that it is very hard to study now when there is no framework, such as tests, etc.
 I wanted to ask the rabbi: I am determined to finish these exams. At home we have software called Chat GPT, and I use it only for questions related to my professional studies. I heard from a friend that she relates to it only as a robot and, Heaven forbid, not as a human being, since it is software that helps me so much in my studies, explains and clarifies the material for me. One of the family members bought a paid subscription so that the chat would answer as accurately as possible. (Parenthetically, the family members do not see any problem with this at all, and neither do I, because it is really opened through the Netfree filter.) I want, with G‑d’s help, to pass the exam successfully and to understand what I am reading in the books. I am not looking for a “heter” (permit); I want to hear whether this is considered legitimate hishtadlut (effort) for earning a livelihood. I will explain to the rabbi: it clarifies the material for me so clearly and gives me answers that I have no one else to get from. Friends who did not pass the exams do not inform me of this, so there is no way to study with them, and the teachers do not have all the free time in the world.
 I want to know what the Torah’s view is on this matter; I truly want to do what HaKadosh Baruch Hu wants from me...
 So I hope I have made myself clear enough.
 Thank you very much, and I would really be happy to hear words of encouragement and support if the rabbi says that this is not appropriate!!
 Another question: is it appropriate to study in the National Library? It bothers me that there are many secular people there, but in the end I come there to learn, so it doesn’t really occupy my mind, but I wanted to know what the Torah’s view is on this issue — is it a kosher place?

Shalom u’vracha,

Answer from the rabbinic halachic board:

In general, artificial intelligence is not a good thing, but there is no prohibition when it is used only for work purposes.
