Show HN: Language Learning on YouTube with AI Exercises

Hi HN,

I made this Chrome extension for language leaning on Youtube. It shows a transcript container when you’re watching a video, and you can select text and get a translation. You can then save the results as a flashcard. When you open study mode, you get language learning exercises generated by ChatGPT.

It’s not fully fleshed out yet, but the basics are there. I really like the idea of learning languages using content that’s relevant to you, as opposed to the standard text book contents.

That being said, the extension is not for complete beginners. I think you should at least know the basics of the language that you’re learning, to really benefit from it.

Releasing bug fixes unfortunately isn’t straightforward, because each release has to go through Google’s review process again, which seems to take a couple of days each time. So here are some caveats:

- Only works with videos that have CC/subtitles available

- If the transcript container doesn’t show up, try reloading the page. Theater mode will make the container move down, so I recommend the normal, non-widescreen view

- In the extension popup, you have to scroll down to see the “Study Cards” button, as it gets moved down by the previews of the cards

- Videos that have embedding disabled don’t show up in study mode

- As usual, responses from ChatGPT can be wrong

Happy to hear what you think and how it works for your language pair!
