Text to Diagram Generator
Convert simple text syntax and markdown outlines into clean vector flowcharts, sequence diagrams, and architecture maps. Free instant SVG & PNG downloads.
A -> B (arrow), [Box], (Round), {Process}, |Database|, A -> B : label (labelled arrow)
One node to two: write A -> B then A -> C on the next line — both branch out side by side under A. See the "Decision" preset for a working example.

Why Text-Based Diagramming Accelerates Software Engineering
Managing visual architecture diagrams as plain text allows engineering teams to version-control system blueprints directly alongside source code in Git repositories.
⚡ Zero Drag-and-Drop Hassle
Describe nodes and directional arrows in straightforward text syntax without fiddling with manual canvas alignment or broken connectors.
📦 Markdown & Git Compatible
Text diagram files diff cleanly in GitHub pull requests, making software architecture documentation easily maintainable by engineering teams.
📐 Crisp High-Resolution Vectors
Export crisp SVG diagrams that scale flawlessly into technical documentation sites, Notion pages, and investor pitch decks.
