Proof of Usefulness Score
Category Standard

Sogou is a major, established technology entity in China, renowned for its dominant Input Method and search engine. While the project demonstrates massive real-world utility and reach (hundreds of millions of users), the submission itself is of low quality, lacking specific metrics and citing 'everyone' as the audience. As a subsidiary of Tencent (acquired in 2021), it fits the 'Much Larger Scale' calibration category. The score reflects its undeniable historical and functional success, dampened by a lack of fresh market timing (legacy status) and a poor submission effort.
