从有没有什么办法能让AI读本站文章继续讨论：
最近在看一些帖子也有类似需求，方便跟AI 讨论，就顺手让Claude 撸了一个。用的是Discourse 自带的功能：
有没有什么办法能让AI读本站文章
开发调优
Discourse 的话，可以通过替换链接拿到markdown 格式的内容，直接复制给AI 会更好 比如这个帖子的链接是：https://linux.do/t/topic/1984943，把t/topic/替换成raw/ ：https://linux.do/raw/1984943 需要分页加：?page=1
脚本会在主贴和最后的回复出新增一个
按钮，点击导出成markdown 格式的文件。
性能开销应该比较小，不会对网站造成什么负担[1]，当然你也可以用的时候再收到打开脚本。
