CodeTrain

Socratic AI coding tutor that never writes your code

CodeTrain is a Socratic AI coding tutor that teaches developers on their own codebase. It breaks a real task into small steps on the learner's repository, asks questions, reviews each line the learner writes, and runs tests; lessons do not advance until steps pass. Works via a website with browser lessons, a local CLI, and a free open-source skill for coding agents. Free tier offers 10 lessons/month from public repos; Pro and Team plans add repo mode, team dashboards, and bring-your-own-key.
