Automated Presentation Synthesis Using Gen AI

This paper presents Automated Presentation Synthesis Using Gen AI, a web-based system that automatically generates structured PowerPoint presentations from three simple inputs: a topic, a target audience, and a tone. Built using React, TypeScript, Vite, and Tailwind CSS on the frontend, the system uses PptxGenJS to produce downloadable .pptx files entirely in the browser without involving any server in the export step. The backend is written in Motoko and deployed as a canister on the Internet Computer Protocol (ICP), a decentralised blockchain-based computing platform by DFINITY Foundation, which means there is no traditional cloud server in the stack. TanStack Query handles data fetching and caching between the frontend and the canister. JWT-based authentication secures all routes, with role-based access control separating regular users from admins. We tested the system across ten topic and audience combinations and confirmed that the preview and the downloaded .pptx file are identical in every case. Generation took between 1.2 and 2 seconds on average, and the export was nearly instant since it runs locally. The system shows that an AI-assisted productivity tool can be built and deployed entirely on decentralised infrastructure without sacrificing usability or performance.
