Create Sankey diagrams in ChatGPT
Last updated November 11, 2026
With the SankeyArt app in ChatGPT, you turn an income statement, cash flow statement or budget into a Sankey diagram right in the chat. This article shows how to add the app, draw your first diagram, save it and change it. For an overview, see SankeyArt in ChatGPT.
Add SankeyArt to ChatGPT#
SankeyArt works on every ChatGPT plan, Free included.
- Open SankeyArt in ChatGPT's plugin directory, or search for SankeyArt in the plugin directory.
- Install SankeyArt.
You can now draw diagrams. You don't need a SankeyArt account for that.
On a ChatGPT Business, Enterprise or Edu workspace, your admin decides which plugins you can install. If you can't install SankeyArt, ask them to enable it for the workspace.
Draw your first diagram#
- Start a new chat and type @SankeyArt.
- Ask for a diagram. Attach a file, such as a PDF of an income statement, or type the figures. For example: "Draw a Sankey diagram of Demo Corp's income statement in $M: revenue 1,000, cost of revenue 600, operating expenses 250, income tax 30, net income 120."
- ChatGPT shows the diagram in the chat. Select Edit in SankeyArt to open it in the SankeyArt editor.
SankeyArt draws only the figures you or your files give ChatGPT. It sees the names and amounts in the diagram, not the rest of your conversation or your files.
Open the diagram in the editor#
In the editor you can fine-tune the diagram and export it. When you open the link, you sign in to SankeyArt or create an account first.
- With a SankeyArt subscription, the diagram goes into your account.
- Without a subscription, you can change the diagram in the editor, but your edits aren't saved. Exports carry a small "created with SankeyArt.com" watermark.
The link keeps working for a year after it was last used.
Save diagrams to your SankeyArt account#
With a SankeyArt subscription, ChatGPT can save your diagrams in your account, open them and change them.
- Ask ChatGPT: "Save that diagram in my SankeyArt account."
- The first time, ChatGPT asks you to sign in to SankeyArt. Sign in and allow access.
From then on, ChatGPT saves each new diagram in your account by itself, without the watermark. If your plan has no free diagram slot left, ChatGPT can't save the diagram, but the editor link still opens it.
Billing admins have no access to diagrams, so ChatGPT can't save or open diagrams for them. See Roles and permissions.
Change a diagram#
Ask for the change in the same chat, for example: "Rename Operating expenses to OpEx and make the cost items orange."
- Saved diagram: ChatGPT changes the diagram in your account. Changes you made in the editor stay.
- Not saved: ChatGPT draws the diagram again, with a new editor link.
To work on a diagram you saved earlier, ask for it by name, for example: "Open my Demo Corp cash flow diagram." ChatGPT lists your diagrams and those your team shares with you. It can change only the ones you may edit. Some settings can only be changed in the editor; ChatGPT then gives you the editor link.
Disconnect SankeyArt#
To stop ChatGPT from using your SankeyArt account, open SankeyArt in ChatGPT's settings and disconnect your account. To remove SankeyArt completely, uninstall it there.
Your saved diagrams stay in your SankeyArt account.
