Diffyn's answer
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

SecureToolsHub was built out of frustration with existing tools that require file uploads, account creation or paid subscriptions for basic security analysis. The goal was to create a suite of professional-grade security tools that anyone can use instantly, for free, with complete privacy.
