Show HN: AI Math Kit – Open Problems. Explore Honestly

AI Math Kit is a browser extension popup that presents 217 open math problems (number theory, calculus, and cross-field mysteries such as the Riemann Hypothesis and P vs NP) alongside 242 plain-language guides to AI and formalized-math breakthroughs, plus prompt templates and an honesty pledge for exploring with AI. It offers Chinese, English, and Japanese interfaces, caches payment status locally, and unlocks full problem explanations, breakthrough details, and prompts via an optional Pro in-app purchase (ExtPay). The developer states the content is introductory paraphrase and does not claim AI has proven any conjecture.
