Test Surely's answer

Surely was born out of real frustration. A QA engineer, overwhelmed by juggling too many testing tools, lost productivity, missed bugs, and rising subscription costs, decided something had to change. After a critical bug slipped through during a late-night testing session, I created Surely to simplify QA work, organizing tabs, streamlining workflows, and using AI to help document issues, without expensive subscriptions. Surely exists to give testers back their time, focus, and sanity.

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.
