Proof of Usefulness Score
You're In Business

The project presents a valid but generic concept (spaced repetition vocabulary builder) that suffers from a highly inconsistent submission and a lack of verifiable traction. The claim that 'most people have used my product' is demonstrably false and severely damages the credibility of the submission. Furthermore, the business type is listed as 'Spelling check platform' while the description describes a memorization tool, indicating a lack of clarity or a pivot. Outside of a 2022 startup listing, there is no significant digital footprint, traffic, or user base found.
