CodeTrain

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.

CodeTrain is a Socratic AI coding tutor that helps developers learn programming through their own codebase. It breaks real tasks into small steps and guides users with questions and feedback. The program requires each step to pass a test before moving on, providing a hands-on learning experience. Users paste the URL of a public repository, and CodeTrain creates lessons based on the code present in it. The tutor prompts users to write code for each step, reviews their work, and runs tests in real-time. The tutor provides hints or shrinks steps if users are stuck, allowing for a gradual learning process. CodeTrain is designed for developers and engineering teams looking to enhance their coding skills and onboarding process. It is particularly beneficial for those who want to learn through real codebases rather than generic tutorials, ensuring a deeper understanding of their specific code practices.
