Generate Object Diagram

A Snapshot of Objects in Action

An object diagram is a snapshot of instances a set of objects and their links at one moment in time. Where a class diagram describes types, an object diagram shows concrete examples.

Use it to illustrate a specific state of your system: the objects currently in memory, their attribute values, and how they reference each other.

What You Can Model

Runtime Snapshots

Illustrate the objects alive at a specific moment, with their current values.

Design Examples

Show concrete instances that make a class design easy to understand.

Debugging Aids

Visualize an object graph when reasoning about memory and references.

Link Semantics

Make instance-level associations explicit for teams and reviewers.

How It Works

  1. Describe the objects name them and their attribute values in plain English.
  2. ArchGPT builds the snapshot our AI creates the instances and their links.
  3. Get your diagram an object diagram renders in seconds.
  4. Export or edit download it, or adjust values in the Draw.io editor.

Try a prompt: "An instance customer1:Customer with name "Alice". It has an open order order1:Order with total 120. The order references one payment pay1:Payment with status "paid"."
