Proof of Usefulness Score
Unicorn Utility

The project is Grammarly, a verified industry leader in AI writing assistance with a valuation exceeding $13B and over 30 million daily active users. While the submission data itself was low-effort (e.g., vague traction claims like 'most people', hallucinated 'fashion' tag, and confuse revenue with market cap), the actual entity is a 'Decacorn' with immense real-world utility and reach. The evaluation prioritizes the verifiable reality of the product over the poor quality of the submission form, though the 'Response Quality' score is heavily penalized.
