SimpliCEFR was born out of personal frustration. While reading English books to improve my reading skill, I constantly hit a wall with complex vocabulary that disrupted my flow and made me lose context. I realized the problem wasn't how I was reading, but what I was reading. To fix this, I built a platform that simplifies books and documents to match any proficiency level, ensuring language barriers never get in the way of learning.
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.
