About Threat Model Companion

Threat Model Companion is a custom GPT designed to assist users in identifying and mitigating security threats. It is built on OpenAI's ChatGPT platform, which provides a conversational interface for discussing threat modeling concepts, analyzing potential vulnerabilities, and exploring mitigation strategies. The tool appears to be tailored for security professionals, developers, or anyone involved in system design who needs guidance on security risk assessment. As a GPT, it operates within the ChatGPT ecosystem, meaning it can process text-based inputs and generate text-based responses, leveraging the underlying AI model's knowledge. The tool is listed as open source and free, though specific usage limits or access requirements should be verified on the ChatGPT platform.
