Built by Paul Mihalick, solo founder of Yellow Moon Software and organizer of FL Today Trippers, a 6,300-member Meetup group in Central Florida. ClueRally was born from years of running large group events and needing a platform that just worked, for everyone, instantly.
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.
