CodeTrain

CodeTrain とは？

A hands-on AI coding trainer that teaches developers on their own codebase, one small step at a time. AI writes the code. CodeTrain makes sure your engineers still understand it, and proves it. The AI plans the lesson, runs your code, and grades every step, but you type every line yourself. Free in-browser tier; Pro adds repo mode with patch-back; Team adds a ramp dashboard + onboarding.
