Ask your AI assistant for a Rubus chart.
Claude, ChatGPT and Copilot can make Rubus charts for you, with the same engine and rules as the add-in.
Ask the AI in PowerPoint or Excel for a chart and you usually get a plain native Office chart; ask a chatbot and you get a rough picture drawn in the chat. Connected to Rubus, the same assistant hands you a clean, labelled Rubus chart instead.
Connect Rubus to the assistant
Add this address in Claude, ChatGPT, Copilot Studio, VS Code or Cursor, then ask for a chart in plain words. The chart comes back in the chat, with a link to download it as SVG or PNG and a block to paste into the Rubus pane.

How to add it, assistant by assistant
Charts drawn through this address are kept for 30 days behind a random link, so the downloads keep working. Charts you make in the add-in stay in your file.
Or have it write a block
An assistant that writes into your sheet, such as Claude in Excel or Copilot, can leave a small rubus: block in the cells, or in a text box on a slide. Click into it and press Draw in the Rubus pane.
