Most AI diagram tools give you a static image you have to rebuild by hand. flow-chart.io generates a live scene graph — every node, connector, and label stays fully editable after generation.
Supported diagram types: C4 model (all 4 levels), BPMN, cloud architecture (AWS/GCP/Azure), ERD, sequence, org charts, DevOps pipelines, swimlane, flowcharts, Mermaid import/export.
Key capabilities: - Plain-English prompts → editable diagrams in seconds - Click any node or connector to rename, recolor, or delete - MCP endpoint for AI agent pipelines (Claude, Cursor, etc.) - Export to PNG, SVG, PDF, PPTX, Mermaid, or JSON - Shareable links and team collaboration on Pro/Team plans
Pricing: - Free: 8 AI credits/month, no credit card required - Pro ($19/month): 200 AI credits, unlimited saves, watermark-free exports, shareable links - Team ($49/month): 350 credits + seats, team workspace
Built for software architects, business analysts, and DevOps engineers who need review-ready diagrams — not a blank canvas.
