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.
