Transforming Personal Finance Coaching through Artificial Intelligence

Abstract

Artificial intelligence (AI) has bloomed in recent years and is gradually becoming an irreplaceable asset in finance,
among other sectors. Personal finance is a subset of finance, which too is being revolutionized due to changing times
and technological advancements, much like AI. Security and proper financial guidance have never been more
important with such significant change. In this study, we use FinBERT, a modern large language model specialized
in the financial domain, for our AI-powered personal finance coach. However, FinBERT, although a cut above the
rest, still has room for growth, so we aim to improve its flaws and enhance its efficiency. We established that
FinBERT succeeded in detecting sentiments in explicit sentiments, but was not usually successful in doing so
correctly for implicit sentiments. FinBERT, despite its limitations, has a high accuracy and is the best model to use
in our study. This model can also be utilised to provide accurate results regarding the overall trend (positive or
negative) of the global stock market. Our results demonstrate that integrating AI in personal finances is feasible and
can successfully aid individuals in making decisions regarding their finances.
