What is Mermaid?

Mermaid is a collaborative AI diagramming platform that helps individuals and organizations visualize technical systems, business processes, project plans, and complex information. Built by the creators of Mermaid.js, the software combines natural language diagram generation, code-based visualization, and interactive graphical editing within a unified workspace. Its AI assistant converts text prompts, uploaded documents, meeting transcripts, screenshots, and code snippets into structured diagrams that users can continue refining. Supported visualization types include flowcharts, sequence diagrams, entity relationship diagrams, Gantt charts, timelines, mind maps, organizational charts, state diagrams, class diagrams, and user journey maps. The platform's Mermaid syntax editor enables users to define diagrams as text while viewing the corresponding visual representation in real time. A synchronized editing interface connects diagram elements with their underlying code, allowing users to select visual components and navigate directly to the relevant syntax. Its drag-and-drop editor supports direct manipulation of nodes, connectors, layouts, and other diagram elements without requiring programming knowledge. AI-assisted editing allows users to describe changes conversationally, maintain context across interactions, and update existing diagrams through natural language instructions. Collaboration capabilities include real-time co-editing, team workspaces, shared links, diagram presentations, and tools for maintaining visual documentation across departments. Mermaid integrates with Visual Studio Code, JetBrains IDEs, GitHub Copilot, Confluence, Jira, Google Docs, and compatible AI assistants through a Model Context Protocol server that supports diagram generation, validation, and rendering.

What is Devici?

Devici helps security and engineering teams build threat models that are consistent, reviewable, and easy to maintain as systems evolve. It focuses on capturing the architecture first, using a visual canvas where teams lay out processes, data stores, external entities, and trust boundaries. As components are described and attributes are applied, Devici identifies relevant threats and suggested mitigations from its built-in library, reducing the manual effort normally required to reason through diagrams or ad-hoc checklists. The tool is designed so that AppSec specialists, developers, and security champions can work together without specialized training. Real-time editing, in-model comments, and version history support collaborative reviews and allow teams to trace how decisions and risks change over time. Reusable templates and patterns make it simple to model common services or shared architecture pieces, helping larger organizations avoid duplicated work across teams. Devici also supports pushing mitigation tasks into existing development workflows through optional integrations, ensuring threat modeling outputs don’t remain isolated from day-to-day engineering. Its structure helps organizations move away from one-off diagrams and inconsistent documentation toward a predictable, repeatable approach that fits into modern development practices. Overall, Devici offers a practical way to raise the quality and clarity of threat modeling efforts without requiring complex onboarding or heavyweight tooling.
