Keep My Secret is an interactive platform designed to simulate AI prompt security challenges. It introduces users to adversarial prompt engineering through a gamified environment where participants take on one of two roles: the “Keeper,” who embeds secrets into system prompts, and the “Seeker,” who attempts to extract them using jailbreak techniques.
The platform aims to provide a controlled setting for practicing prompt-injection attacks and defensive strategies, making it relevant for developers, security researchers, and AI practitioners interested in improving model resilience. By combining learning with interactive competition, Keep My Secret allows users to explore vulnerabilities in large language models, test attack vectors, and understand secure prompt design principles. This hands-on approach can support skill development in AI security without risk to production systems.
