SparkChart for PlantUML and Mermaid rendering in the browser. Create, visualize, and edit diagrams with AI assistance. SparkChart: The Ultimate Text-to-Diagram Workspace SparkChart is a lightweight, high-performance extension for developers, architects, and technical writers who want to build professional diagrams without the friction of drag-and-drop tools. By treating "Diagrams as Code," SparkChart allows you to render complex visualizations instantly using industry-standard syntax. ## Dual-Engine Support PlantUML: Create robust, UML-compliant sequence diagrams with a dedicated live editor and real-time preview. Mermaid.js: Full support for all Mermaid charts, including Flowcharts, Gantt charts, Entity Relationship Diagrams (ERD), Mind Maps, and User Journeys. ## Key Features Live Rendering: Watch your diagrams update in real-time as you type your code. Professional Templates: Kickstart your project with built-in snippets for common architectural patterns. High-Quality Export: Save your work as SVG or PNG files for seamless integration into GitHub, Jira, Notion, or your internal documentation. Privacy-First: Your diagram code stays in your browser. No external accounts or cloud storage required. ## Future-Ready with Local AI SparkChart is built for the next generation of web browsing. We have integrated a powerful AI assistant designed to generate diagrams from natural language prompts and automatically refactor your chart logic. Note: These AI features are currently deactivated. They will be automatically enabled as soon as Google Chrome rolls out official support for Gemini Nano (Built-in AI) on your device. This ensures the AI runs entirely locally on your machine, keeping your data 100% private. Stop drawing. Start coding. Ignite your documentation with SparkChart.
