In their own words
Mermaid
Mermaid is an open-source JavaScript tool that turns Markdown-inspired text definitions into diagrams and visualizations. Its diagram types include flowcharts, sequence and class diagrams, state diagrams, Gantt charts, timelines, mindmaps, Git graphs, use case diagrams, and event modeling diagrams. Users can also describe an idea, upload a document, or paste a transcript to generate a diagram, then refine it in a context-aware conversation. The platform supports real-time co-editing, click-based adjustments, and shareable live links that recipients can open without logging in. Mermaid can be used in its Live Editor, installed as an npm dependency, loaded from a CDN, or deployed through its API. Listed integrations span IDEs, office tools, and community projects. It imports.mmd files and exports PNG, SVG, and Markdown; version history is available. The free Basic tier allows up to six diagrams, a size limit of 60, 15 AI credits, and one team and project creation. Plus costs $10 a month billed annually; Premium costs $20 a month billed annually.
SmartDraw
SmartDraw is a diagramming tool for creating scaled floor plans and professional diagrams, from building layouts and evacuation plans to flowcharts, organizational charts, network diagrams, UML diagrams, and mind maps. SmartDraw AI can turn natural-language prompts into editable diagrams and floor plans. Templates and automatic layout adjustment help shape diagrams as users add, move, or delete elements. Teams can edit together, comment, and review version history. The service supports Linux, macOS, Windows, and the web, though its desktop launcher opens the web app and requires an internet connection. Files can be imported from formats including PDF, Visio, Lucidchart, and common image files, then exported as JPEG, PNG, SVG, PDF, or Visio. SmartDraw lists integrations with Microsoft 365, Google Workspace, Jira, Confluence, Azure, AWS, GitHub, ChatGPT, and Claude. The paid product has a free trial but no free plan; Team requires at least three users. SmartDraw was founded in 1994 and is headquartered in The Woodlands, Texas.
