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.
SpyFast's answer:
Hello everyone 👋
I built this tool because reading and summarizing all the reviews from Google Maps takes forever, and it's nearly impossible to truly grasp the overall perception of a business manually. So, I created SpyFast to make understanding your customer reviews much easier and faster. This is my first launch, so every single word of feedback is incredibly helpful for me. I truly appreciate any insights you can offer and would love to hear what you think!
