Proof of Usefulness Score
Category Standard

Sololearn is a highly established, market-leading mobile coding education platform with verifiable Series B funding and tens of millions of users. While the project itself has immense real-world utility and traction (far exceeding the calibration baseline), the submission quality was exceptionally poor (lazy, vague claims like 'everyone' and 'most people'), which necessitated significant penalties to the Quality Factors. The score reflects the high value of the entity, tempered by the lack of effort in the specific funding/evaluation request.
