See It In Action
A beautiful canvas for your ideas
Experience a modern, intuitive interface designed for speed and creativity.
How It Works
From idea to diagram in seconds
OpenCharts combines the power of AI with an intuitive canvas to help you create professional diagrams faster than ever before.
Describe what you need
Type what you want in natural language—a flowchart, whiteboard layout, meeting notes, or a presentation. Upload a PDF and let AI extract it, or answer guided questions to skip the blank canvas.
AI builds it for you
Watch as AI creates nodes, connections, and layouts automatically. Switch between flowchart, whiteboard, and notes modes on the same canvas—or let AI pick the best format.
Customize, present, and share
Fine-tune with drag-and-drop editing, hit present for a cinematic node-by-node walkthrough, invite your team for real-time collaboration, or export as PNG, SVG, PDF, Mermaid, or JSON.
