We like to compare ourselves to IKEA: Well-designed products that fit the needs of many and can be sold at a low price, because you do the assembling yourself. Which, in turn, leads to a better experience for you and your customers. We offer the features most people need, and we deliberately do not offer specialized features that few people need in order to reduce complexity and cost.
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.
