What's the story behind your product?

REQVERA's answer

REQVERA was built around a recurring problem in complex bids: producing a strong response is not the same as proving that the final package is complete, supported and ready to submit. REQVERA was created to add that missing final-control layer between finished writing and submission.

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.
