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.

Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.
