Proof of Usefulness Score
Gaining Momentum

Keymate.AI is a well-established ChatGPT plugin with significant verifiable traction (250k+ users, ~5k paying subscribers), generating an estimated $2.5M in lifetime revenue. While the project demonstrates high real-world utility by adding long-term memory and search to LLMs, the submission itself contained hyperbolic claims ('most people have used my product') and confusing financial terminology. Furthermore, the reliance on OpenAI's ecosystem presents a substantial market timing risk as native features (SearchGPT) encroach on its core value proposition. The score reflects a solid, revenue-generating business with valid platform risk.
