Product Overview
What is Mermaid?
Mermaid (mermaid.ai) is a diagramming and visual collaboration platform that evolved from the widely adopted open-source Mermaid.js project, which has accumulated over 86,700 GitHub stars. It lets users generate diagrams by describing them in natural language or Mermaid's Markdown-style syntax, with an AI layer that handles layout automatically — no drag-and-drop required. The platform supports a broad range of diagram types including flowcharts, sequence diagrams, ER diagrams, Gantt charts, C4 architecture diagrams, and more. Trusted by over 3 million users and 200,000 companies, it integrates natively with VS Code, GitHub Copilot, Confluence, JetBrains, and Microsoft Office tools, fitting directly into existing developer and business workflows.
Key Features
Text-to-Diagram Generation
Describe any system or process in plain language or Mermaid syntax and the platform renders a structured, formatted diagram instantly — no manual layout work needed.
Wide Diagram Type Support
Covers flowcharts, sequence diagrams, ER diagrams, Gantt charts, C4 architecture diagrams, state diagrams, user journey maps, and more, all from the same workspace.
Multi-Mode Editing
Users can write in code, refine with AI prompts, or click to edit visually — all three modes stay in sync so the diagram always reflects the latest logic.
Deep Tool Integrations
Native plugins for VS Code, GitHub Copilot Chat, Confluence, JetBrains, and Microsoft Office let teams diagram without switching between applications.
Real-Time Collaboration
Co-edit diagrams live, leave comments, and share with external stakeholders — with access controls, custom encryption, SOC2 compliance, and SSO for enterprise teams.
Git-Native Version Control
Because diagrams are text-based, they slot naturally into Git workflows — commit, diff, and roll back diagrams just like source code.
Use Cases
- Software Architecture Documentation : Developers and system architects can map services, dependencies, and infrastructure (AWS, Azure, GCP) quickly, then embed diagrams directly in READMEs or code reviews.
- Database Schema Design : Data engineers and analysts can model ER diagrams before writing SQL, making table relationships and constraints visible to the whole team early in the process.
- Project & Process Planning : Project managers and business analysts can build Gantt charts, timelines, and workflow diagrams to track progress and surface bottlenecks without specialized design tools.
- Technical Documentation : Technical writers and DevOps engineers can create and maintain living documentation — sequence diagrams, CI/CD pipelines, and system flows — that stays up to date alongside the codebase.
- Stakeholder Communication : Consultants, founders, and strategists can turn abstract ideas into clear visual narratives for presentations and proposals, directly from their existing workspace.
