Nheengatu is a CLI tool that uses LLMs to translate and simplify EPUB books to specific CEFR language levels, featuring a smart two-pass pipeline for lower proficiency levels to improve vocabulary coverage and prevent language leakage. It's interesting because it combines EPUB processing, intelligent text chunking, and adaptive LLM prompting to solve a specific problem in language learning and accessibility.

Target audience: language learners, educators, accessibility advocates
