Sketch an entity relationship diagram from a list of entities

Before a database schema is code, it is an argument about what relates to what. Name the entities and the AI draws the ER diagram, each entity with its relationships and cardinality, ready for the team to argue over on the board.

The prompt: Entity relationship diagram for a multi-tenant whiteboard: organization, member, user, board, board grant, share link, comment thread, comment. Show the relationships with their cardinality.

A real result: a multi-tenant whiteboard's entities, with the cardinality of each relationship on its line.

How the ER diagram generator works

  1. 1Open the AI prompt, list the entities and ask for the relationships with their cardinality.
  2. 2The AI draws an entity per box and labels each relationship; Kaavit lays them out and routes the lines.
  3. 3Move entities to group them, rename them, or add one by hand and connect it.
  4. 4Pin a comment to an entity to discuss a field or a constraint.

Questions

Does it generate SQL or migrations?

No. It is a database diagram for thinking and agreeing; your schema stays in your code.

Can it show fields and types?

Ask for them and the AI writes them into each entity's box as text. Kaavit has no dedicated table shape.
