We built the tool we needed

I built Paper Grinder at 16 because I was stuck repeating the same mistakes. Spending hours on past papers, marking myself, but never truly understanding what went wrong. The feedback loop was broken.

Now it helps thousands of students avoid mine. This isn't just an AI tool — it's the feedback system I wish I had when I was grinding past papers.
