Lathe – Hands-On LLM Learning Tool

An AI-powered tutorial generator that creates structured, source-backed coding lessons for any technical topic, forcing learners to code by hand instead of copy-pasting. Targets developers who want to actually learn new domains rather than skip past them with AI.

Developer education is under real pressure right now: GitHub Copilot and ChatGPT have made it trivially easy to ship code without understanding it, and there's a growing backlash from engineers who recognize they're accumulating gaps. The closest substitute is Codecademy or a course platform like Egghead, but neither generates lessons on-demand for arbitrary topics with source citations, so there's no direct incumbent. The $2k–10k/mo band is realistic if it finds a niche of self-directed developers willing to pay $15–30/month, but that ceiling is low and will require unusually strong retention to avoid churn — people who actually want to learn slowly are a smaller segment than they sound. The biggest risk is that the core constraint (forced hand-typing, no copy-paste) feels like friction rather than pedagogy to most users, and they abandon it within a week.
