CodeTrain / Compare / A roundup of Socratic AI coding tutors
Which Socratic AI coding tutor is for you?
We make CodeTrain, so you might expect this page to end with "use CodeTrain". It mostly will not. A tutor that teaches with questions instead of answers is a good idea whoever builds it, and more than one team has built one, each for a different learner. Here are the real options, what each does, and who it suits. If the one for you is not ours, use that one.
| tutor | who it is for | how it teaches | how you get it |
|---|---|---|---|
| Code.org AI Tutor | Students in grades 6-12 on Code.org courses | Socratic questioning built into the course rather than answers | Inside select Code.org courses, in English |
| Khanmigo | Learners working on math, science and coding | Guides you to find the answer yourself | Monthly or annual payment, account holder 18 or older, in the United States |
| ChatGPT study mode | People who want concepts explained and checked in a chat | Guides with questions, explains step by step, checks your understanding | Across ChatGPT plans on web, iOS and Android |
| CodeTeach | JavaScript debuggers who want to commit to a hypothesis | Asks for a written hypothesis before every hint | Open source, runs locally, with or without an Anthropic API key |
| KodeKloud AI Tutor | People learning Kubernetes, Docker, Linux, Terraform, Python, AWS, Azure and Git | Real-time help inside its labs and lessons | Free for all users |
| CodeTrain | Developers who want to learn on their own repository by typing every line | Breaks a task into small steps that run and must pass | Free plan with ten lessons a month, no card, in beta |
Pick Code.org's AI Tutor when the learner is in grades 6-12 and already on Code.org, or when a teacher is choosing a course. It is built into select courses and designed around Socratic questioning, so the questioning is part of the course rather than an add-on. It is in English, which is worth knowing before you plan a lesson around it.
Pick Khanmigo when the learner is studying math, science or coding and wants a guide that leads them to the answer themselves. It comes from Khan Academy, a nonprofit. Note the terms before you sign up: the learner plan needs a monthly or annual payment, and the account holder must be 18 or older and live in the United States.
Pick ChatGPT study mode when you want the concepts explained step by step and your understanding checked, in a conversation. It guides you with questions instead of giving the answer right away, and it is available across ChatGPT plans on web, iOS and Android. If you are on your phone, pick this one and come back to the rest later.
Pick CodeTeach when you are debugging JavaScript and want to be forced to think before you get a hint. It requires a written hypothesis, "I think the bug is because ___", before every hint, and that discipline pays off. It is open source under MIT, runs locally, and works with or without an Anthropic API key.
Pick KodeKloud's AI Tutor when you are working through its labs and lessons on Kubernetes, Docker, Linux, Terraform, Python, AWS, Azure or Git and want help right where the exercise is. It gives real-time help inside those labs and lessons, and it is free for all users.
Pick CodeTrain when the lesson is from your own repository or any public one. It breaks a task into small steps, you type every line; each step runs and must pass before the next opens. The tutor never writes your code, and a code-level guard removes a pasteable solution before it reaches you. It records the steps you completed unaided; a team lead sees that on the team dashboard. The free plan is ten lessons a month, no card. We are in beta.
How to choose
Start with where the learning happens. If it is a Code.org course, use the tutor built into it. If it is school subjects, Khanmigo covers math, science and coding. If it is a conversation you want, on your phone or laptop, study mode is there. If it is Kubernetes or its neighbours, KodeKloud's tutor is inside the labs and free. If it is your own repository, and the point is that you write the code, that is CodeTrain. The honest shortcut: pick the tutor that lives where you already practice, because the one you open is the one you keep using.

How CodeTrain teaches this
No videos and no multiple-choice quiz at the end. Each lesson is a handful of small steps in a real editor. You type the code yourself, it runs, and the tutor reviews what you actually wrote. It will not hand you the answer, and the step doesn't advance until your code passes. What you get at the end is a record of which steps you wrote unaided, not a completion percentage.
These curated courses are the starting point, not the product
Everything in this catalog is a curated course we wrote by hand. They exist so there is something to start on. What CodeTrain actually does is build a lesson on demand: name any topic you want to understand and it writes one for you on the spot, or paste any public repository and it teaches you that codebase from the code that is really in it. You are not limited to the list below, and most people stop using it within a session or two.
