In a similar vein, I made https://www.wikdict.com/reader/sv-en/ , which adds translation pop-ups to each word in the input text. The cool thing compared to manually looking up words is that it will translate idioms/phrases (if they are in the dictionary) and split compound words (if they are not in the dictionary) into their translatable parts.

I also have some code to add the translations as pop-up footnotes to epub files (I like to use that on my e-reader). That is not mature enough yet for public usage, but if anyone wants to help testing it, I can run some e-books through it. Just let me know!
