Introducing OpenCharts: The AI-Native Flowchart Platform
OpenCharts is a free, AI-native web platform that turns PDFs, PowerPoints, images, and text prompts into editable flowcharts, whiteboards, notes, and presentations in seconds. Built by Open Charts Inc, it ships real-time multiplayer collaboration, 120+ templates, AI export to PNG/SVG/PDF/PPTX, and a public MCP server you can connect to Warp, Claude, Cursor, or VS Code.
What is OpenCharts?
OpenCharts is an AI-powered platform for creating flowcharts, whiteboards, and rich notes. Upload a PDF, PowerPoint, or image and Theo extracts the processes and builds an editable flowchart in seconds. Or simply describe what you need in plain language, and Theo generates it instantly.
Why we built it
Traditional diagramming tools require you to manually drag shapes and draw connections. That's tedious when you already have the process documented in a PDF or in your head. OpenCharts flips the workflow: start with your content, let AI handle the layout, then refine and collaborate in real time.
