I second Wallabag — IMO "slick" is a nice-to-have, not a must-have when weighing software choices against each other.
At least Wallabag has a long and robust track record of not selling users out to bullshit tech corpos. That counts for more in my book than shiny surfaces.
Ah yes, the anglocentrism of software development. I gave up on Google translate years ago because it clearly only catered to English speakers. The other way around was such ham fisted mistranslations with English syntax, it was basically useless.
