Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

UseSam.com's answer

UseSam was created after seeing how many businesses lose revenue simply because they can’t answer the phone consistently. Missed calls often mean missed jobs, missed bookings, and missed trust. The idea was to build an AI that behaves like a great front-of-house team member – polite, reliable, and always available – without the cost or complexity of a traditional call centre.

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.
