I built Writing9 to help people improve their IELTS Writing skills.
IELTS = International English Language Testing System.
Back when I was learning English, I struggled with writing and wished there was a tool that could give real feedback – so I made one.
Writing9 checks essays, points out mistakes, and gives an estimated IELTS band score. It’s like having a personal tutor, but way faster and more affordable. Thousands of people use it every day…
