Napkin

Napkin AI turns typed or pasted text into editable visuals — diagrams, charts, icons, and infographics — and into full presentation decks, with no prompting or design skill required. Two products share one text-to-visual engine: Napkin Visuals (standalone diagrams and graphics) and Napkin Slides (beta AI presentation agent). Napkin also ships a developer API (currently a developer preview) for generating visuals programmatically: submit text, poll the asynchronous request, and download the results as SVG, PNG, or PPT. The API authenticates with account bearer tokens or an OAuth 2.0 authorization-code flow. Napkin is an AI company backed by CRV.

Napkin publishes 1 API on the APIs.io network: Visuals API. Tagged areas include Company, Ai, Visualization, Diagrams, and Infographics.

Napkin’s developer surface includes documentation, API reference, getting-started guide, changelog, support, engineering blog, pricing, and 22 more developer resources.
