As answered by people managing PATTERNISSE and Diffyn.
PATTERNISSE's answer
PATTERNISSE puts many jobs in one place. Drop in a pattern and it tags itself, stores it in a neat online shelf, and shows it on a dress or wall right away. You can send big files with one link, see which designs a client opens, and add a pay-now button without leaving the page.

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
PATTERNISSE's answer
Our founders were pattern designers fed up with messy folders, printed look-books, and late payments. They built a small fix for themselves, friends wanted in, and PATTERNISSE grew from there.
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.
PATTERNISSE's answer
One of the five biggest wallpaper brands in Europe, multiple large U.S./Portuguese textile mill, and hundreds of indie pattern studios rely on PATTERNISSE every day (names under NDA).
