  ## Why LangKit? 🚀
  
  While general ML observability platforms and NLP libraries exist, LangKit provides a pre-built, opinionated set of LLM-specific metrics and profiles for continuous monitoring of performance, safety, and cost. It's designed to integrate seamlessly with your LLM applications, offering out-of-the-box insights into text quality, relevance, security, and privacy.
