Mermaid
Mermaid is an AI-powered diagramming tool for creating flowcharts, sequence diagrams, ER diagrams, and other visuals from text, code, or a visual editor. It is designed for individuals and teams that want diagrams they can edit, share, and keep in sync with their working documents.
What Mermaid is
Mermaid is an AI-powered diagramming tool that turns text, code, or prompts into editable diagrams. The site positions it as a way to go from notes to a living diagram quickly, with options to start in AI, use Mermaid syntax, or refine visuals with a drag-and-drop editor.
It supports common diagram types such as flowcharts, sequence diagrams, ER diagrams, timelines, mind maps, org charts, state diagrams, class diagrams, Gantt charts, Git graphs, and architecture-style diagrams. The product is aimed at people and teams that need to create, edit, share, and maintain diagrams where they already work, including code, docs, and collaboration tools.
Core capabilities
Build with code
Write diagrams in Mermaid syntax and let the layout render automatically, with support for editing in text-first workflows and version control in Git.
Visual editing with live sync
Adjust nodes, labels, edges, shapes, and colors by clicking or dragging, while the underlying code updates automatically.
Plugins and editor integrations
Embed Mermaid in tools such as GitHub Copilot and Confluence, and use VS Code support to work directly from a codebase.
Team collaboration and sharing
Collaborate on a shared canvas, share feedback live or asynchronously, and keep diagrams updated across a team.
Present from the workspace
Create, share, and present diagrams from the same workspace without switching to a separate presentation tool.
Where Mermaid fits
Software and system design
Map product logic, systems, dependencies, and implementation steps as you build, using either text or code as the starting point.
Developer documentation
Document processes, data models, and code relationships in a form that can live alongside repos, READMEs, and technical documentation.
Team communication
Turn rough notes into diagrams for presentations, planning sessions, and stakeholder updates without moving to a separate design tool.
Cross-team review
Collaborate on diagrams in a shared workspace when feedback needs to happen live or across time zones.
Education and training
Create diagrams for teaching concepts such as workflows, sequences, and structures in a format that can be edited and reused.
