Program for automatic comparison of texts in two languages?

Question

English learning tools

A few months ago, there was an article on Habré written by a guy who solved such a problem: two texts are given - for example, in Russian and English. His program shows them in parallel - in two columns, you highlight a phrase in one text - it is automatically highlighted in another. You scroll one text - another is scrolled in parallel.
I've been looking for this article for an hour and a half, and just by browsing the feed, and by keywords - I can't find this article! Although I remember exactly what it was.
Worst of all, I can't even think of keywords to search for her. Most of the words that are definitely there - like "English" - come up with so many results that it makes the search useless.
I would be grateful for your tips! (I want to find this article)
