Show HN: App to facilitate language learning on Youtube

Hi HN, I think many are aware how useful Youtube is for language learning. This app that I'm building helps you get the most out of it.

In its simplest form, it's simply a mobile UI for Youtube that lets you copy text from the transcript (Youtube's app doesn't let you do that).

More advanced features are a built-in dictionary and translator, web search for names, slang etc. and a flashcard system that creates exercises from your saved words.

It's using AI in different places, but I'm making sure that it's always grounded with a lot of real world data, to avoid hallucinations. I think it works pretty well.

It's currently available in Test Flight (iOS) and in the Google Play Store, if you register as a tester. There's also a Chrome extension that's already live. Let me know what you think!
