Artificial Intelligence (AI) has been one of the most transformative and emerging technologies. It is the effort of human understanding in training a robot-like machine to act like humans. Artificial intelligence aims to improve learning, thinking, and perception. Libraries are the core of academic activity; they attract teachers, students, and the community. The essential source of distributing knowledge and information to society deserves an upgrade. This review study will discuss the changes and upgrades an academic library need. In remote learning, digital libraries are precious. They are now one of the most important sources of information for learners in this education sector. With AI's aid, this transformation is achievable for the libraries. AI has many use cases in libraries, including reference systems, automation, book reading chatbots, robots, etc. We'll mainly cover how these methods are implemented in libraries using AI topics such as natural language processing, and pattern recognition. A Survey analysis id done for more descriptive analysis of AI in libraries. The Implementation of AI has specific benefits and drawbacks mentioned in this paper. It may appear like AI is distancing librarians from their patrons, but utilized to help librarians and improve library administration systems.
