The ChatBot Assistant supports archaeologists and heritage professionals during fieldwork by enabling voice‑based data entry, real‑time validation, and rapid access to excavation or archival information, even in low‑connectivity environments. It is designed to streamline the “validate‑as‑you‑collect” workflow by reducing manual entry errors, speeding up observations, and allowing practitioners to interact with structured data while keeping their hands free for excavation tasks. Its offline-first design ensures that field documentation never stops, with all data synchronizing automatically once connectivity becomes available.
