The medium of Artificial Intelligence has transformed the game of content marketing and has further gone on to open up avenues to unprecedented personalization. This research assesses how AI-based personalization impacts consumer engagement as well as brand loyalty through the creation of emotionally relevant and contextually appropriate experiences. This study has heavily relied on primary data collection based on a structured questionnaire from 60 respondents stationed in the Coimbatore district along with a thorough review of secondary literature. Descriptive statistics, Friedman rank analysis, and ANOVA were used for the statistical analysis which proved that AI personalization strongly enhanced consumer perception, trust, and satisfaction. For example, the relevance, emotional appeal, and accuracy of the content developed by AI are well positively correlated with user engagement; however, privacy concern is still the highest barrier to trusting AI. It has also been established that AI-based personalization is an emerging set of strategies for brand loyalty in such a complex digital world. However, the paper underlines the fact that the contents generated through AI are ethical, transparent, and authentic for necessary safeguards concerning consumer trust. Future research on longitudinal impacts, cross-cultural variations, and ethical dimensions of AI in marketing is necessary to understand its transformative capacity in a full-fledged sense. It will be able to bring marketers and brands closer to acquiring better insights regarding how to efficiently use AI towards sustainable growth based on closer relationships with consumers.
