How Open‑Source AI Tools Can Auto‑Generate PPTs, Mobile Apps, and Web Apps

Presentation AI: Auto‑Generate PPTs

Presentation AI is an open‑source tool that creates attractive PowerPoint slides from a single sentence. Users input a topic (e.g., "Chinese university student practice report PPT"), select language and slide count, and the AI produces a complete outline, content, and design. It offers nine theme templates, AI‑generated or royalty‑free images, real‑time preview, editing, and one‑click export. The project is built with Next.js and React and is completely free.
