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.
Brightcast.news's answer:
Brightcast was born from a simple frustration: traditional news makes us anxious, yet staying informed matters. The founder, based in Switzerland, wanted a news experience that was honest about the world's problems but equally focused on solutions. The result is an AI-powered platform that proves good news isn't naive — it's necessary.
