当你看到一个不错的bilibili视频，想把内容用文字的方式提取出来，提取之后，再用AI自动帮你总结，应该如何做？
今天我们就介绍下如何用工具来完成这个需求，全部都是免费的。
是这样，这两天看到一个访谈类节目，关于2023年大模型总结和未来方向的视频。这个视频接近2个小时，我又不想去听，想看文字版本的，文本版本也可以保留下来。那么怎么搞？
简单来说需要两个步骤，一是把bilibili的这个视频下载下来，获取把音频提取出来。二是把视频或音频的内容转文字提取出来，最后用AI工具总结。
我们先说第一步。
1、下载bilibili视频
这里介绍一个开源的工具：downkyi
git地址：https://github.com/leiurayer/downkyi
这个工具可以帮你下载bilibili视频，支持批量下载，支持音视频提取、去水印等功能。
作者提供了安装包，直接下载就能使用，非常方便。
解压后的页面是这样的，你直接把需要下载的视频的地址黏贴进去就行
我把需要下载的视频地址帖进去，然后效果如下，接着你需要先点击解析视频，然后再点下载视频即可
等待它下载完成，就可以了，就是这么方便。
下载完成后，你可以去工具箱里，去掉视频水印，也可以把音视频分离出来。
2、audio/video to text
把视频或音频的内容转文字提取出来
第一步我们成功的把bilibili视频和音频下载下来了，那第二步我们看看如何转成文字。
这里介绍一个好用的工具，阿里的通义听悟
我们在首页直接上传音频或视频就可以了
等待解析完成，我们就可以进去看到文字版了，你可以把内容导出到本地。
通义听悟比较不错的点：
（1）除了把原文输出出来，它还帮你把发言总结和要点回顾也同时整理出来了，省去了再去找其他AI工具帮你总结的步骤
（2）提供了摘取、标记的功能，你可以在原文的基础上，自己进行一些人工的编辑和整理。
（3）提供了翻译的功能，你可以直接对内容进行翻译，不需要再单独用翻译软件多操作一步了。
以上就是用downkyi和通义听悟这两个工具，帮你下载bilibili视频并提取文字内容和总结的方法，希望可以帮助到有需要的朋友。

Keep up the amazing work!
