Stop Wrestling with Drag-and-Drop Diagram Tools

You’ve been there. Spend 45 minutes dragging boxes and arrows in Lucidchart, then someone asks for a change and you’re back to square one. The diagram lives on someone’s desktop as a .png that’s already outdated.

There’s a better way. Mermaid.js lets you write diagrams as plain text — version-controlled, AI-generatable, and rendered automatically in GitHub, Notion, and dozens of other tools. With 74,000+ GitHub stars and 8 million users, it’s become the standard for diagrams-as-code.

This course teaches you Mermaid from zero — then shows you how to use AI to generate diagrams in seconds instead of minutes.

By the end of this course, you’ll be able to:

  • Write flowcharts, sequence diagrams, class diagrams, ER diagrams, state diagrams, and Gantt charts in Mermaid syntax
  • Use ChatGPT, Claude, or Gemini to generate diagrams from natural language descriptions
  • Render diagrams in GitHub, Notion, Obsidian, VS Code, and the Mermaid Live Editor
  • Apply best practices for readability, accessibility, and version control
  • Document an entire project with multiple interconnected diagram types

What You'll Learn

  • Explain how Mermaid.js converts plain text into professional diagrams
  • Create flowcharts, sequence diagrams, and class diagrams using Mermaid syntax
  • Build entity-relationship, state, and Gantt diagrams for real projects
  • Use ChatGPT, Claude, and Gemini to generate and refine Mermaid diagrams from natural language
  • Apply diagram best practices for readability, accessibility, and version control
  • Design a complete project documentation set using multiple diagram types

After This Course, You Can

→ Create professional flowcharts, sequence diagrams, and ER diagrams from plain text in minutes instead of hours
→ Generate diagrams instantly from natural language descriptions using ChatGPT, Claude, or Gemini
→ Embed version-controlled diagrams in GitHub, Notion, Obsidian, and Confluence for always-current documentation
→ Document complex systems and architectures with multiple interconnected diagram types in a single project
→ Add diagramming-as-code proficiency to your technical resume, valued by engineering teams and documentation roles

What You'll Build

Complete Project Documentation Set
A full documentation package for a real or sample project — including flowcharts, sequence diagrams, ER diagrams, and architecture diagrams — all written in Mermaid and rendered in GitHub or Notion.
AI Diagram Generation Workflow
A documented workflow comparing AI-generated Mermaid diagrams from natural language prompts across ChatGPT, Claude, and Gemini — with prompt templates, output quality analysis, and best practices.
Mermaid Diagrams with AI Certificate
A verifiable credential proving you can create professional diagrams as code, use AI for diagram generation, and document systems with multiple interconnected diagram types.

Frequently Asked Questions

Do I need any coding experience?

No. Mermaid uses simple, readable text syntax — not a programming language. If you can write a bulleted list, you can write a Mermaid diagram.

Which AI tools work with Mermaid?

ChatGPT, Claude, and Gemini can all generate Mermaid code. Claude renders diagrams inline via Artifacts. This course covers all three.

Where can I use Mermaid diagrams?

GitHub, GitLab, Notion, Obsidian, VS Code, Confluence, Jira, and many more. Mermaid renders natively in most developer tools.

Is this course really free?

Lessons 1 and 2 are free. The rest of the course and the certificate come with Pro.
