In their own words
DataDocs
DataDocs is a cloud database documentation tool that uses AI to generate documentation and keep it aligned with schema changes. It currently supports PostgreSQL and MySQL; SQL Server and Snowflake are listed as coming soon. One-click generation creates documentation, while search covers the documentation and data catalog. DataDocs scans for schema changes and reflects them in the documentation. If an asset’s documentation is wrong, users can regenerate it and provide feedback; manual editing is listed as planned. The service requests read-only metadata access and says it does not access or store the database’s actual data. Its web application and extraction service run in separate VPCs, with credentials stored in a restricted vault. DataDocs is aimed at small businesses, freelancers, and agencies, and is positioned as documentation software rather than data governance. The Free plan is free for one source, 25 assets, and weekly refresh. Growth costs $25 a month; Premium costs $100 a month.
