waaat.ch's answer
Got tired of spending 40 minutes browsing through Netflix/Prime/HBO/whatever every time I wanted to watch something, or searching for recommendations on Reddit that matched a specific vibe. Asking ChatGPT also became boring fast since I'd have to constantly switch tabs to go watch trailers or get more details.
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.
