About CodeTrain

CodeTrain is a Socratic AI coding tutor: it asks questions, reviews what you write, and runs your tests, but never writes the code for you. Free to start. Two steps, about a minute, and the first one is going to catch you. The tutor's replies are pre-recorded, so it knows the handful of ways this lesson usually goes wrong. The real one reads whatever you actually wrote, and it is free for ten lessons a month.
