Spellchecker, normalizer, and LLM context generator for Luxembourgish, built from the official orthography rules. 600+ common words, 80+ misspelling catches, FNEL scouting vocabulary, and a CLI that works as both letz and lëtz. An experiment in giving AI the linguistic context that official tools don't provide.
