Show HN: CodeTrain – an AI tutor that refuses to write code for you
a day ago
- CodeTrain teaches developers on their own codebase by having them type every line, ensuring understanding without autocomplete.
- It uses a Socratic tutor that never gives answers, but asks, nudges, reviews code, and runs tests to build real comprehension.
- Code stays local on the machine; only small prompt snippets are sent to the model (or nothing with a custom API key).
- Team onboarding is streamlined: new hires ramp in weeks with interactive lessons, and a dashboard tracks progress and understanding.
- The tool includes spaced repetition to resurface weak areas, and supports cross-device sync and privacy controls for teams.
