Pre-built agents produce complete work products such as risk registers, compliance gap reports, and validated invoice batches instead of a raw chat log.
Reads uploaded documents plus live website URLs, and connects to Google Drive, SharePoint, and SQL databases with auto-sync to keep content current.
