How it works

Make a ERD in three steps.

  1. 1

    Describe what you need

    Type a sentence or paste rough notes. No blank canvas and no manual layout.

  2. 2

    Toft drafts the artifact

    Toft picks the structure, writes the copy, and lays out the finished piece.

  3. 3

    Edit, then export

    Refine any part by prompting or editing directly, then export to share or hand off.

FAQ

Questions about ERD Maker

What is an ERD?

An entity relationship diagram shows database tables, fields, keys, and relationships. Toft generates one as editable diagram structure from schema notes.

How do I make an ERD with AI?

List the entities and important relationships. Toft turns them into tables, primary keys, foreign keys, and relationship lines you can refine.

Can I paste an existing schema?

Yes. Paste SQL-like notes, table names, or product requirements and ask Toft to infer the ERD.

Does the ERD stay editable?

Yes. The ERD is rendered from Schematex DSL, so changing a table or relationship updates the diagram.

Make your own ERD.
