Fast to make. Easy to trust. Everywhere you already work.
Shape an idea in seconds
Type it, say it, or upload a doc. Mermaid goes from input to diagram before you've finished the thought.
Get the right diagram, not just a diagram
Flowchart, timeline, requirement diagram, sequence — Mermaid AI suggests the shape that fits what you're actually building.
Keep your data yours
Secure access controls, trusted encryption, SOC 2 compliance, and SSO that fits your existing setup.
Diagram where you work
Render in your IDE, embed in docs and wikis, or generate straight from Claude, VS Code, and Cursor through our MCP server.
Edit together, in real time
Co-edit live, share with one link (no login required), and turn a conversation into a decision.
Stay in your flow
Prompt right inside the code panel or canvas and watch the diagram change around you. No context-switching, no syntax hunting — just describe it and keep going.
What do you need to figure out?
Or start with a diagram type:
Create with AI
Describe it, upload a doc, or paste a transcript — and get a diagram you can shape from the first draft. Mermaid AI holds context across the whole conversation, so your diagram grows as your thinking does.
Build with code
Write in Mermaid syntax and watch the diagram lay itself out. Click any node to jump to its code, or click the code to find its shape on the canvas — you always know where your changes live.
Edit and collaborate, your way
Prompt inside the editor. Adjust with a click. Snap layouts with node alignment, reattach edges without rewriting a line, and share a live link when you're ready.
Stay in the tools you love
Use Mermaid inside GitHub Copilot, Confluence, and more — or connect our MCP server to generate, validate, and render diagrams straight from Claude, VS Code, and Cursor. No manual syntax needed.
Integrate with VS Code
Turn infrastructure and systems into diagrams right from your codebase.
Present without leaving your work
Create, share, and walk people through your diagrams — no export, no second tool.

“Making multiple flowcharts look good felt tedious. Mermaid flipped that – now I focus on my notes, and Mermaid takes care of the diagramming.”
“Mermaid solved a major portability problem for us, making charts behave like code. The real game-changer is using AI to analyze our software so we can visualize complex logic instantly.”
“From load balancers to Kubernetes, Mermaid helps me document architecture with my team: Markdown-native, version-controlled, and easy to share.”
“Mermaid is my mind tool — I map client’s systems 5-10 times faster, catch misreads quickly, and iterate in real time.”
“Mermaid transformed three things: clarity, collaboration, and speed. Onboarding becomes simpler and what used to take 30+ minutes in GUI tools takes under five.”
“Mermaid is the bridge between thinking and communication: I structure logic in text with AI, then turn it into clear visual maps, operating models, and strategy flows.”
