What to ask ChatGPT

Write as you would to a colleague. A few prompts to start with:

  • Turn this income statement into a Sankey diagram.
  • 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.
  • Rename Operating expenses to OpEx and make the cost items orange.
  • Draw a Sankey diagram of my monthly budget in €: salary 4,000 and side job 500; rent 1,400, groceries 600, transport 250, leisure 400, and I save the rest.
  • Save that diagram in my SankeyArt account.

Draw for free, save your edits with a subscription

Free, without an account

Draw as many diagrams as you like with ChatGPT, then refine them in the SankeyArt editor, faster and more precisely than by prompting.

Your edits aren't saved, and exports carry a small "created with SankeyArt.com" watermark.

With a SankeyArt subscription

Your edits are saved to the SankeyArt cloud, and ChatGPT can open your saved diagrams and update them.

No watermark on exports, and more export options.

When ChatGPT first needs your account, it asks you to sign in to SankeyArt. See plans
