MyIPNow.net's answer
MyIPNow started as a personal side project to create a cleaner, faster alternative to the cluttered IP-lookup sites that dominate search results. The goal was simple: deliver precise information instantly while maintaining user privacy. Over time, it evolved into a full suite of free internet diagnostic tools, built with consistency and transparency in mind, from IP lookups to WHOIS queries and speed testing, all without compromising design or performance.
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.
