Ekalavya is a terminal-and-web coding tutor. It authors lessons, diagrams, and interactive visuals into a canvas you keep; it walks you along a forest of mastery — learning groves on a winding path rather than a flat wall of nodes; and after every session it shows you, honestly, whether you are actually getting better.
Its one non-negotiable: it measures your unaided accuracy and keeps it separate from AI-assisted work. Paste a full answer and the round is lost — the streak breaks, merit drops. Type it yourself and you reclaim it. The point is not to look productive; it is to become capable.
