Llettuce: The AI Tool Mapping Messy Medical Records to Standard Code

Llettuce uses AI to automate mapping informal medical terms to OMOP standard concepts. Its architecture combines a local LLM, vector-based semantic search, and database queries. Users can interact via GUI or API, uploading terms or files, while results are displayed clearly. Llettuce ensures accurate, GDPR-compliant healthcare data conversion without requiring cloud services.
