## Description

Turn AI answers into diagrams on Mac. Connect ChatGPT/Codex or Gemini by MCP in a few clicks, use Qwen Code too, and preview Mermaid, Graphviz, PlantUML, or SVG locally.

Ask an AI to explain a workflow, system, database, project, or idea as a diagram. SourceCanvas gives that answer a real home on your Mac: a native window where you can see it, check it, edit it, and export it.

Your AI diagram companion on Mac
• Work with Codex, ChatGPT, Gemini CLI, Qwen Code, Claude Desktop, Cursor, Visual Studio Code, and other local MCP hosts
• Configure ChatGPT/Codex, Claude Desktop, Cursor, Visual Studio Code, Gemini CLI, and Qwen Code from SourceCanvas; use Copy MCP Connection Settings for other compatible hosts
• Let the AI validate and render SVG, Mermaid, Graphviz DOT, or PlantUML through seven MCP tools, Resources, and Prompts
• Keep one native AI Preview window updated while a task moves from planning to implementation, tests, and delivery

Diagrams for everyday needs
• Flowcharts for processes, decisions, instructions, and customer journeys
• Sequence diagrams for conversations, APIs, and service interactions
• Architecture, component, class, state, UML, and ER diagrams for systems and databases
• Gantt charts, timelines, Kanban boards, and mind maps for projects, lessons, research, and personal planning
• Pie, XY, Sankey, quadrant, requirement, Git, packet, and other supported Mermaid diagrams

Review and export without fuss
• Open .svg, .mmd, .mermaid, .dot, .gv, .puml, .plantuml, .iuml, and .pu files, including matching Markdown code blocks
• Use Automatic detection, syntax highlighting, find and replace, line/column diagnostics, zoom, pan, Fit Screen, and readable backgrounds
• Save the editable source or export SVG, vector PDF, and PNG 1x/2x/3x for reports, slides, documentation, classes, and sharing

Local by design
• Core SVG, Mermaid, Graphviz, and PlantUML rendering runs on the device; no account or remote rendering service is required
• External SVG resources are blocked by default and use secure remote access only when you explicitly allow the document's named hosts
• PlantUML uses a single-file offline model: include/import directives and URL or file images are blocked, while safe inline features remain available
• SourceCanvas does not upload documents, record AI conversations, enable automatic tool approval, or include advertising analytics

AI-assisted workflows are controlled by you. During long coding tasks, a connected Agent can reuse one preview ID to show current architecture or progress. Updates are initiated by the connected AI Host; SourceCanvas does not monitor chats, code, logs, or tasks on its own.

The MCP Agent is available on macOS. iPhone, iPad, and Apple Vision Pro provide the same local document preview and export tools without exposing Agent Service.
