The project 'Grai' (grai.io) is a legitimate Y Combinator (S22) backed data observability tool, but this specific submission contains critical errors, hallucinations, and false claims. The 'Business Type' is incorrectly listed as 'AI-powered property valuation' (confusing it with a different 'GRAI' real estate tool), and the traction claims ('most people have used my product') are demonstrably false. While the underlying technology has merit, the submission quality is effectively spam.
