I'm working on https://openlang.ai (please try it on desktop, there are some bugs on mobile)

It's a web app to learn languages using podcasts, Youtube and chatgtp. I have been using these language learning techniques myself and I know they work better than duolingo or similar apps. I'm biased of course, but that's the reason I'm building this in the first place, I don't think there's any other app as effective out there.

It's not done yet, but it's usable on desktop. Any type of feedback is appreciated.
