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.

Capture your ideas, then swipe to see which ones really matter
Capture thoughts instantly with a simple interface so nothing is lost; ideas drop straight into your evaluation flow.
Evaluate ideas like a dating app — swipe right to upvote, left to discard — for repeated, mood-independent judgment.
Organize ideas in lists, apply filters and track status, then mark winners as 'to implement' when it's time to decide.
Come back regularly, add new thoughts and let ideas grow and develop over time rather than stall after capture.
