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.
SiteQuest's answer:
The idea came from a simple frustration: constantly leaving work to open a browser.
Whether writing code, designing interfaces, or researching information, every Alt+Tab interrupted concentration and slowed momentum.
SiteQuest was created to remove that friction by bringing the web directly into the workspace. Rather than replacing existing browsers, it complements them, providing instant access to websites and AI with a single hotkey while keeping users focused on their work.
