How it works

Tell us about your entities, tables, or data model. Include relationships (one-to-many, many-to-many) if you know them.

MyMap's AI generates an ER diagram with entity boxes, attributes, primary keys, and relationship lines.

Add columns, change relationships, or ask AI to extend the schema. Export as PNG or PDF for docs or wikis.

الأسئلة الشائعة

Is the ER diagram maker free?

Yes — you can create ER diagrams for free without signing up. Free accounts get a generous number of AI messages per month.

Does it support many-to-many and one-to-one?

Yes. Describe your cardinality (one-to-many, many-to-many, one-to-one) and the AI will render the appropriate relationship notation in the diagram.
