Hi, oefu.
I’ve just found an extension that works on both Iqiyi and WeTV. It’s called “GlotDojo”. Look it up on the Chrome Web Store.
Pros:
-You can press Alt+C to copy the current subtitle. If you’re using a Mac and an iPhone/iPad, this means you can copy to Pleco to quickly look up words.
Cons:
-No export to Anki with screenshots and audio. This alone makes me keep using LLN.
