Presentation Assistance System- PresentMate

Abstract

Presentations play a critical role in academic and professional communication; however, presenters often face challenges such as forgetting key points and responding to spontaneous audience questions. Existing tools primarily focus on content creation and lack real-time intelligent assistance during presentation delivery. This paper introduces PresentMate, a real-time AI-powered presentation assistant designed to enhance presentation effectiveness and user confidence. The system extracts content from presentation files, generates summaries, key points, and anticipated questions, and provides real-time assistance through overlays and integrated interfaces. It also incorporates speech recognition to capture audience questions and generate context-aware answer hints. The system is built using a modular architecture consisting of a FastAPI backend, Next.js frontend, Chrome extension, Electron desktop application, and PowerPoint Add-in. Experimental analysis demonstrates improved response time, enhanced presentation flow, and increased user confidence. The proposed system provides a scalable and practical solution for intelligent presentation assistance.
