YouTube Video Embed with Interactive Transcript Plugin

I was looking for a Plugin/Widget or anything useful for YouTube video embed with interactive transcript in my WordPress website. Here some example:

Is there anything out there will be useful for me? If nothing available.
How can i manage to do that? Custom Plugin will be needed?

Note: YouTube videos will be posted as a Post, so this have to be dynamic.
