The problem, as people describe it

A tradesperson turned tutor highlights that apprenticeship training systems have not evolved with technology, leaving gaps that frustrate learners and instructors. He built AI‑driven tools to provide personalized study modes, project tracking, and sovereign AI for trade education, but currently relies on tutoring to survive while scaling the solution. The opportunity is to create a dedicated AI platform that serves trade apprentices and educators seeking effective, independent learning tools.
