“U-Review does like around 25,000 comments a week. And uh we get 10% of them actually get some feedback. And only 4% of the PRs actually get some negative feedback. Uh we also saw that um the overall addressal rate was uh around 67%”

uReview routes each change to generators by risk and complexity, then rates, filters and deduplicates comments before posting. Uber tracks whether developers act on each comment (the “addressal rate”) and reports costs down 60% against a naive setup. Quoted from YouTube’s auto-generated captions.
