PowerPoint to flowchart with AI
OpenCharts converts PowerPoint slides containing diagrams into editable flowcharts in seconds. Drop a PPTX file, and Theo extracts each diagram's structure — nodes, connections, decision branches — into a real React Flow canvas you can refine, theme, and re-export. Ideal for cleaning up legacy decks, modernizing process maps, and adding multiplayer collaboration to slide-based diagrams.
How it works
- 1
Upload your PPTX
Click ‘AI Extract’ in the editor and drop your PowerPoint file. Files up to 10 MB are supported.
- 2
Pick the slide(s)
When the PPTX has many slides, Theo lets you pick which diagram(s) to extract. Single-slide extraction is the most accurate.
- 3
Theo rebuilds the structure
Theo identifies SmartArt, drawn shapes, connectors, and labels, and rebuilds the diagram as native flowchart nodes and edges with auto-layout.
- 4
Refine and re-export
Edit, theme, and collaborate in real time. Export back to PPTX (fully editable), PDF, PNG, SVG, DOCX, XLSX, or JSON.
What you get
- Supports SmartArt, drawn flowcharts, and freeform connector shapes inside PPTX
- Preserves text labels, branch conditions, and node grouping where possible
- Theme-aware re-export: pick a brand theme and Theo applies it to the rebuilt diagram
- Real-time multiplayer collaboration on the rebuilt flowchart
- Free on every plan
Frequently asked questions
Will the layout from my PowerPoint be preserved?
Theo focuses on the structural relationships rather than pixel-perfect positions. After extraction, you can apply auto-layout (top-to-bottom, left-to-right, radial) to get a polished result. The rebuilt diagram is editable, so any layout adjustment you want is one drag away.
Can I re-export to PowerPoint?
Yes. Every flowchart can be exported to fully editable PPTX, plus PDF, PNG, SVG, DOCX, XLSX, and JSON.
What about SmartArt?
SmartArt diagrams are extracted as structured node-edge graphs. The rebuilt OpenCharts version uses native nodes and edges so the result is editable with all OpenCharts tools (themes, collaboration, comments).
Are slide animations preserved?
No. The extraction targets the static structure of the diagram, not slide-show animations. If you need animated reveals on the rebuilt diagram, use the OpenCharts AI Presentations builder.
Is this free?
Yes. Extraction is included on every plan including the free tier. Paid tiers raise AI credit limits.
