How do I add embedded YouTube videos to previously posted content automatically?

I have a site with over 1000 articles, and I would like to know if there's a plugin that can search the title (or the tags) of the article on YT and add a video from YT to the article.

There must be a plugin that can do it.

Thank you!

A WordPress plugin like Video Embed & Thumbnail Generator could automate embedding YouTube videos based on titles or tags.

I appreciate it, I will look into it.
