 #### Q. 关于 AI PPT
 
-A. 我不想蹭AI的热度，但无奈太多人将AI看得太重了，于是我做了这个DEMO（它真的没那么复杂），目前此功能仅作参考，内部实现了最基础的AIPPT生成逻辑，即：模板定制 + AI生成数据与模板结合 + 配图替换。为控制成本暂时只能做到这里，但为了达到生产环节的效果，你还需要做更多，例如更多的模板、更细致的AI工作流程。
+A. 首先需要说明，AIPPT不是PPTist的重点，现在或以后都不是，它只是PPTist众多功能中非常小的一部分而已，并且是比较简单一部分，你可以理解为这只是一个跟风的小功能点，我不想蹭AI的热度，但无奈太多人将AI看得太重要太复杂了，于是我做了这个DEMO（它真的没那么复杂），目前此功能仅作参考，内部实现了最基础的AIPPT生成逻辑，即：模板定制 + AI生成数据与模板结合 + 配图替换。为控制成本暂时只能做到这里，但为了达到生产环节的效果，你还需要做更多，例如更多的模板、更细致的AI工作流程。
 
 注：配图替换仅提供方法，不提供实际演示功能，你需要自己提供图片源接入（如AI文生图、图库搜索匹配等方法）
