What is it?

PPTist is a browser-based slide editor that replicates most commonly used Microsoft PowerPoint features. It covers text, images, shapes, lines, charts, tables, video, audio and LaTeX formulas, with editing features such as undo/redo, alignment, grouping, element and slide animations, and a presenter view with annotation tools.

The project can import and export PPTX, JSON and its own pptist format, and export slides to images or PDF. It also supports template-based AI PPT generation and ships a data schema that lets AI produce slide page data directly. PPTX fidelity is stated as roughly 85%+ on import and 95%+ on export, and complex animations, special charts and advanced styles may differ from the original.

Built with Vue 3 and TypeScript, it does not depend on a UI component library, which makes styling and feature extension easier for web developers. It requires Node.js 20 or later to run locally.
