LangChain 发布开源设计代理 Content Studio，可在 Slack 中生成品牌一致的视频、图形和演示文稿，其输出基于 HTML、数据规格和动画时间轴而非扁平图片，支持低成本局部修改。
Open-sourced Humanize PPT, an HTML PPT skill designed for presentations. It reorganizes outlines using AST (Audience, State, Transfer) logic, combined with downstream rendering skills to produce PPTs truly usable for presentations, addressing issues like uneven information distribution and content emptiness.
The author tested 7 open-source PPT Skill projects and points out that the core reason for ugly AI-generated PPTs is the lack of proper aesthetic constraint systems. These projects improve the design quality of AI-generated PPTs by compiling aesthetic rules, and the author introduces each project's features and suitable scenarios.
