SlideSpeak
SlideSpeak is an AI-powered presentation tool that lets users chat with PowerPoint files, summarize slides, and generate new presentations from documents or prompts. It helps extract insights, create slides quickly, and turn content into clear, structured presentations with minimal effort.
