Maestro LivebookPRO's answer
Born from the frustration of paper binders and unsynced tablets during live shows — the goal was a single tool where the whole group's screens follow the same page automatically, with no manual coordination needed
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.
