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.
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.
