What's the story behind your product?

Simple Allergy Alert's answer

I have a severe nut allergy myself. After a life threatening anaphylactic reaction while travelling, I got tired of printing allergy cards every time I visited a new country. I built Simple Allergy Alert so I could generate a card on the spot, in the local language, with an emergency card ready in case something went wrong. I use it myself on every trip.

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.
