Here to answer some of these questions: We offer a huge part of our corpus for free, and we offer a super cheap Premium offer in order to still make some money. We use linguists, teachers, and native speakers to curate our courses, but we're a small team of three people who just started this a few months ago, not all of our content is yet verified and corrected. We're working together with 2 institutions for endangered languages, offer them a "cms"-like interface to host their own courses alongside our existing courses. Yes, there are bugs. Yes, placements aren't great. But we're working on it! Goal is: Combinations. Make it possible to learn French from Arabic. Make it possible to learn Igbo from German. And so on. There's no fraud involved (how even do you imagine anything fraudulent here, it's a language learning app with a massive free tier), we're just trying to make it accessible.

Thanks for all the feedback, this filled up our backlog for surely a few weeks.
