Hello! I'm relatively new to this sub but wow I wish I'd joined years ago it's been incredibly helpful.
YouTube videos have always been a favorite way for me to learn Japanese — I'm a big beleiver in comprehensible input as a major pillor in my Japanese learning approach. A few months ago I got annoyed with existing tools for extracting vocabulary from YouTube videos. There are a number of different services that do this — and they are all great!
But for me, I wanted something that was simple, and more focused on extracting Japanese from videos so I could study vocabularly separately. Most of the tools are general purpose and I didn't like their accuracy with Japanese. Otherwise, they were focused on reading Japanese plus English as you watched. I wanted to separate the watching from the studying.
Anyways, it's totally free to use! I hope you find it useful: https://app.seikai.tv
