Chat with your data and get charts and diagrams in seconds
Describe the chart you want in plain language and receive a rendered visual, using a chat-style prompt instead of a chart configuration panel.
Go beyond charts to structured diagrams, so process flows and relationships can also be produced from a written description.
No installation or local setup is required — open the site, type your request and work from the generated output.
Produce an initial version of a visual quickly, which you can then refine or restyle rather than building from a blank canvas.
