Build with AI

You describe it. Mermaid builds it.

Describe what you want, upload what you already have, or prompt right inside the canvas. Mermaid AI handles the structure so you stay in flow.

Pattern Background

Edit diagrams with a prompt

Adjust layout, labels, and style in plain language — like chatting with a design assistant.

Change the look in seconds

Swap colors, themes, and layouts with a prompt or a click.

Collaborate visually

Work together in the Visual Editor or your favorite plugins, live or async.

Build diagrams faster

Turn plain text into polished diagrams in seconds, not hours.

Skip the syntax, stay precise

AI writes clean syntax for you, so you never have to memorize it.

Keep your data yours

AI prompts from our paid users aren't used for training, so diagrams stay encrypted and private.

From text to diagrams, in seconds

Mermaid AI handles the complexity so you can focus on the outcome, not the output.

Mermaid’s AI-powered diagrams, in action

“Mermaid turns 30–60 minutes of diagramming into 5 — often the difference between doing it or skipping. And the built-in AI made the process even faster.”

“Mermaid and AI makes documenting multi-agent systems and data pipelines fast, clear, and reliable alongside code.”

“Mermaid pairs naturally with AI — Markdown-native diagrams that stay versionable, shareable, and easy to refine.”

“Mermaid has become an indispensable tool for our architecture discussions as it allows us to represent complex workflows”

“The real game-changer is using AI to analyze our software and generate Mermaid syntax so we can visualize complex logic instantly.”
