VoucherGPT: A Novel Approach for Personal Email Voucher Management Using Large Language Models

Promotional emails often contain valuable deals and discounts that are left unutilized due to the volume of such emails a user receives. This paper introduces VoucherGPT, an AI-powered solution built on top of the GPT-3.5 model, to navigate this challenge. VoucherGPT automatically identifies, classifies, and summarizes promotional content in emails, enabling users to easily access and utilize the value contained in their inboxes. We engineered specific prompts to instruct the model for optimal extraction and summary. We design an end-to-end system that is embedded directly in the user’s email inbox as an add-on, and we are developing a browser extension for real-time notifications during online shopping. VoucherGPT was evaluated using both objective and subjective metrics. Human-In-The-Loop (HILT) evaluation showed high satisfaction with the quality of summarization, and the system achieved high precision and recall in identifying specific parts of the promotional emails.
