Storage as software: programmable, decentralized data infrastructure
Define privacy, encryption, replication and reliability rules per dataset so storage behavior follows your specification instead of a provider's defaults.
Spread data across several cloud providers or self-hosted nodes from one control surface, reducing single-vendor dependency.
Tailor encryption and access strategies to each application's data sensitivity, keeping sensitive workloads isolated without separate tooling.
Regulatory requirements are modeled as first-class storage settings, helping teams document and enforce data-handling policy.

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.
