langextract — LLM-Powered Structured Information Extraction

Extract structured data from unstructured text with character-level provenance. Every extracted entity traces back to exact character offsets in the source document.

When to use this skill

  • Extracting entities, relationships, or facts from unstructured text
  • Processing clinical notes, legal documents, research papers, or reports
  • Building NLP pipelines that need citation-level traceability (not just extracted values)
  • Long-document extraction (chunking + parallel workers + multi-pass for recall)
  • Replacing fragile regex/rule-based extraction with LLM-driven schema enforcement
  • Generating interactive HTML visualizations of annotated text
