What CastorDoc is
CastorDoc is a cloud data catalog for discovery, governance and self-service analytics, with pricing available on request and a 14-day trial. It gathers metadata from a company’s data stack to map infrastructure and supports natural-language search for data assets. Automated discovery and AI documentation help maintain definitions, ownership and lineage. Column-level lineage connects sources to business-intelligence tools, while pipeline, report and impact lineage are also listed. CastorDoc AI can write SQL, debug code and document models using metadata such as definitions, prior queries and lineage. Administrators enable these features because they are disabled by default; the maker says customer data is not used and metadata is sent as context to the OpenAI API. Governance includes PII/PHI tagging, role- and attribute-based controls and approval workflows. Access is through web, API and Chrome extension, with connectors for major warehouses, BI and collaboration tools.
