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 The diagram lives on someone’s desktop as a .png that’s already outdated.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.

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?
Yes — all 8 lessons, quizzes, and the certificate are completely free.
