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.
Keze.io's answer:
I was not trying to look amateur requesting credentials over email. This is also a security nightmare. I was not happy with the tools available. So, I built Keze.
