checked out the tool and think it's a cool idea! one piece of feedback though - I actually feel like the inverse product would be more helpful for me. What I mean is replacing ~95% of english text with words (Chinese in my case) that I can understand, and leaving the remaining ~5% (words I definitely don't know) in English.

At least for me, there's large value in consuming bigger volumes of Chinese to get me used to pattern-matching on the characters, as opposed to only reading a smaller amount of harder characters that I'm less likely to actually encounter
