What's the story behind your product?

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.

DesiCalc.in's answer:

Tax and registration costs in India are confusing and the online tools are gated, ad-stuffed, or push paid services. DesiCalc was built to offer accurate, verified, instant calculators that are completely free and private — nothing leaves the visitor's device.
