What's the story behind your product?

Built out of frustration with existing UK property calculators that were either outdated, full of ads, or designed to funnel you into a mortgage application. PropertyCalc was created to be the simple, reliable tool that should already exist.

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.
