About CodeTrain
CodeTrain is a Socratic AI coding tutor that teaches developers on their own codebase by breaking tasks into small steps, asking questions, reviewing each line, and running tests. Every step must pass before advancing, providing proof of learning rather than completion percentages. It runs in the browser with no installation, or as a free open-source agent that keeps code on your machine. The core tutor is free and open source, while a managed tutor is available from $24/mo.
