The solution they’ve come up with is a platform that provides targeted, adaptive practice exercises built around engaging content that yields actionable data for educators to monitor a student’s progress. It might seem that this puts them in competition with the AI-based correction app Unicorn Grammarly, but this would be missing the point. The idea is to provide an interactive learning and teaching resource, not simply correct mistakes once made.

It’s won the platform impressive funding in recent years, boosted no doubt by surging VC interest in the edtech sector that’s seen investment in it rise to over $16B globally. With half of US school districts already using the platform, NoRedInk looks set to establish a leading position going forwards.
