Show HN: Lathe – Use LLMs to learn a new domain, not skip past it

Lathe is an LLM-powered tool that generates hands-on, source-backed tutorials for technical topics. It combines a Go CLI with LLM agent skills (Claude Code, Cursor, Codex) to create interactive learning experiences, encouraging users to type code manually and engage with exercises, side-notes, and citations. The tool aims to fill gaps where human-written tutorials are unavailable, such as niche domains like building a 3D slicer in Erlang.
