Smart English Prep's answer

Smart English Prep was created to solve a common problem: IELTS learners often face slow feedback, expensive tutoring, or scattered study resources that make consistent progress difficult. The product was built to bring writing, speaking, reading, and listening prep into one focused workflow, backed by feedback that blends AI speed with human expert judgment.

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.
