Overview

About Szum

Szum is a chart design system with a compact grammar, chart-aware validation and curated themes. Charts can be produced through AI agents, a web editor, an API and SDK, or a Figma plugin, with PNG and SVG export and interactive embeds.

What it does

Szum renders charts from a simple JSON spec, validates them and applies consistent publication-quality styling across channels, including AI-generated charts.

Where it fits

Sits between data and publishing, replacing ad-hoc chart styling in apps, documents and design files.

Who it suits

Developers, designers, analysts and content teams producing charts for products and publications.
