It converts to lätt svenska (simplified Swedish), which is usually intended for beginners / students and I believe is the point here. The translated text is missing a lot of details, though, yes.
If you're in the US, I recommend bokon.se for ebooks -- they're one of very few sites that accepts American credit cards. Otherwise, you're kind of stuck with libraries (if you have one nearby with a good foreign language section) or packing your suitcase. I'd also recommend Historiepodden on Spotify and Sommarprat on sverigesradio.se -- don't really watch TV myself but others here have mentioned svtplay.se if you're into that.
