CastorDoc
CastorDoc is a cloud data catalog for data discovery, governance, and self-service analytics.
What CastorDoc is
CastorDoc is a cloud data catalog for data discovery, governance, and self-service analytics. It gathers metadata from a company’s data stack and maps the data infrastructure, while natural-language search helps users find assets. Automated discovery and AI documentation maintain definitions, ownership, and lineage. Column-level lineage connects sources to BI tools and shows downstream effects of changes; pipeline and report lineage are also provided. CastorDoc AI can write SQL, debug code, and document models using business definitions, previous queries, and lineage as context. Administrators activate these features because they are disabled by default, and the maker says customer data is not used by the AI. Generated SQL should be reviewed. Governance tools include automated PII/PHI detection and tagging, role- and attribute-based access controls, and auditable approval workflows supporting requirements such as GDPR, HIPAA, and CCPA. The product is available through the web, API, and Chrome extension, with connectors for major warehouses, databases, BI tools, and identity services. Pricing is available on request, with a 14-day trial.
