Mermaid Chart
Mermaid Chart turns plain-text Mermaid syntax into diagrams and refreshes the visual when the text changes. Mermaid AI can also create diagrams from natural-language prompts or uploaded PDF, Word and plain-text files. Supported types include flowcharts, sequence diagrams, Gantt charts, ER diagrams, timelines, mind maps, org charts, state and class diagrams, pie charts and quadrant charts. Teams can co-edit in real time, comment and share live links. Official plugins and add-ons connect it with development environments, AI assistants, documentation tools and office products, including VS Code, JetBrains IDEs, Cursor, Windsurf, Claude Code, ChatGPT, Confluence, Jira, Google Docs, Word and PowerPoint. Mermaid AI exports PNG and SVG files. Mermaid MCP can validate and render diagrams without authentication; authenticated users can use it to manage diagrams and projects. Basic costs nothing and includes three diagrams and 15 AI credits. Plus costs $12 a month billed annually; Premium costs $24 a month billed annually. Trial and paid-tier content is not used to train Mermaid AI models; Basic-tier content may be used to improve services.
