SliceTube alternatives

I love the product, and for students like us who don't speak English as their first language, this is gold. It's really frustrating to go on YouTube, copy the link to the video, paste it in a wordbook, and use it, even though it's a problem-solving product. We can not do this every time for every video. There should be the ability to search YouTube videos directly through Wordbook. It will save a lot of time and provide a really good experience for me as a user.
