I Like the cleanliness of your website. Especially when compared to the bloated sources.
But I’ve got to admit, that I fail to understand the purpose of your website aswell. I’ve clicked through some examples and compared it to the source material. So far, the only thing that was scrapped on your site have been the notes or helpful texts.
Maybe you could create an about page or show the user what content was scrapped (doesn’t have to be a wordcount. Can be something like: 5min readtime vs 1min readtime)
Show the user, why they should use your site instead of the original.
