Ren is an AI-powered marking and feedback platform for schools and junior colleges. Teachers mark faster with full rubric transparency; students receive personalised, comment-level feedback on every assignment — not at the end of term, but within days of submission. Every mark is tagged by topic, question type, and thinking level, building a longitudinal record of how each student learns and where they persistently struggle — across both STEM and Humanities subjects. This powers three levels of insight: targeted intervention data for teachers, personalised revision pathways for students, and programme-wide performance analytics for administrators — across subjects, cohorts, and years.
