rustcoach - Learn Rust with an AI coach that won't write it for you

RustCoach teaches Rust by making you write it. An AI coach (built on Claude) writes each lesson for you, remembers what you got wrong, and re-tests it before moving on. Every lesson ends with a real assignment: your code compiles and runs against cargo tests and clippy in a sandbox, then gets reviewed like a pull request. Stuck? You get hints and a line-by-line trace, never the answer. 16 chapters, spaced review cards. Free to start, $49 once, no subscription.
