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 — just say what the erd is for.

  2. 2

    Toft drafts the erd

    Toft picks the structure, writes the copy, and lays out a finished editable erd diagram in seconds.

  3. 3

    Edit, then export

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

Why Toft

A finished piece, not a starting point.

Finished, not a blank canvas

You get a real, laid-out editable erd diagram — not a template to fill in or a canvas to arrange yourself.

Editable to the frame

Change the text, structure, colors, and layout by prompting or editing directly. Nothing is locked.

A real artifact, not a screenshot

Toft generates genuine, structured work you can refine and export — not a flat image of one.

One idea, many formats

Turn the same content into a deck, one-pager, infographic, or diagram whenever you need it.

FAQ

ERD Maker questions

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.

Describe what you need. Toft returns the finished, editable editable erd diagram.
