Common questions about ai data model diagram generator
Conceptual shows entities and relationships only, logical adds attributes and keys without vendor types, physical pins exact column types and constraints for a target database. Ask for the level you need, or generate conceptual first and ask the AI to "take this to physical for Postgres".
Paste DDL, a dbt schema.yml, or even a bullet list from a design doc — the AI reconstructs the model from whatever structure exists and you edit from there instead of starting at a blank canvas.
Mostly in schema reviews and onboarding: export a PNG into the design doc, or embed a live view in Notion or a README so the model in the doc is the model on the canvas, not a screenshot from three quarters ago.
Yes — say "model this as data vault" (hubs, links, satellites) or "as a star schema" and the AI applies that pattern. There are dedicated generators for both if you want to start there.
