CodeTrain teaches developers on their own codebase, one tiny step at a time. The AI plans, runs, and grades; you type every line. Free in-browser tier.
Ethan Ludwig
CodeTrain is a hands-on AI trainer for developers. Instead of writing code for you, it turns any question, repo context, or onboarding task into a short lesson on your own codebase: two to six small steps, each one typed by you in an editor with an instant run/test loop. The tutor grades every step, asks Socratic questions when you miss, and shrinks the step when you're stuck. Pro adds repo mode with a single reviewable patch-back of the code you wrote; Team adds ramp dashboards and onboarding journeys. Free tier runs in the browser, ten sessions a month, no card.
