The AI tutor that refuses to write your code
1 follower
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.

Hey PH, founder here.
I built CodeTrain after noticing what a year of AI autocomplete does to a team: everyone ships faster but explains less. Assistants optimize for producing code. CodeTrain optimizes for producing engineers who understand it, so it does the one thing no other AI tool will: it refuses to type your code. It plans a lesson from your own codebase in 2-6 tiny steps using repo mode, you write each one in an editor with instant run/test feedback, and it grades every step. Stuck? The step gets smaller. The answer never comes for free.
What to try in your first two minutes: sign in (free, no card), ask it to teach you something you've been faking your way around, and even try to make it write the code for you. Losing that argument is the product working.
Free tier: in-browser trainer, 10 sessions/month. Pro ($24/mo): repo mode on your real projects, one integrated patch-back of the code YOU wrote, BYOK if you'd rather run lessons on your own key. Team ($32/seat): ramp dashboards and onboarding journeys generated from your repo.
PH-only: code PRODUCTHUNT at checkout for 20% off three months.
I'll be here all day. Hard questions about pricing, privacy, or whether AI tutoring is snake oil are welcome; I'd rather answer those than collect confetti.
