## Summary

Lighthouse is a new digital assistant that lets users explore the Civil Rights period of the United States using multimodal data from South Carolina. The authors present it as the first system of its kind.

The assistant uses a neuro‑symbolic design that blends a large language model with rule‑based symbolic solving, aiming to reduce potential harm while maintaining coverage. Evaluation involved both factual objective questions and subjective ones, with a dataset of subjective question‑answer pairs built by aggregating answers from independent experts.

Lighthouse can access over 18k primary sources from a variety of collections and is designed to be easily extended. The work highlights how AI can support historical research while prioritizing trustworthiness and safety.
