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.
Devrian.in's answer:
DEVRlAN started as an independent developer project focused on making common technical tasks faster and simpler. The goal is to bring useful browser-native utilities into one focused workspace, while keeping privacy and local processing at the center of the experience. It is being developed based on practical developer needs and feedback.
Devrian.in's answer:
DEVRlAN is currently an independent developer project and does not have publicly disclosed major customers. The product is available for developers and technical users to use directly.
