Turn any code snippet into an interactive flowchart you can actually read
Paste a snippet in Python, JavaScript, TypeScript, Java, C, C++, Go, Rust, and others to get an interactive diagram of its logic.
Generate flowcharts, sequence diagrams, class diagrams, and user-journey views depending on what you need to explain.
A written explanation accompanies each diagram so you can verify the AI's reading of the logic against your own.
Download results as PNG, SVG, or PDF, or share a link to the diagram with teammates and reviewers.

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.
