We built Markus to change that — cutting marking time while delivering instant high quality feedback on handwritten work. What began as a sector wide fix now supports thousands across the UK. Teachers spend hours marking with slow feedback. We built Markus to deliver instant, quality feedback on handwritten work, saving time and improving learning.
