The openingWhy this idea is overlooked
Most AI education tools are digital-native and ignore the reality that huge amounts of math work are still done by hand on paper. A platform that reads and validates handwritten mathematical reasoning with over 90 percent accuracy addresses that overlooked segment, monetized through low per-page and per-copy micro-transactions plus subscriptions. It is overlooked because handwriting recognition of math reasoning is technically hard, and that difficulty is exactly what makes a working product defensible.
