What types of flow diagrams can I create?

Process flows, data flows, workflow diagrams, decision trees, system interaction flows, user flows, and any diagram that shows sequential or branching flow. Describe your diagram type and content — the AI adapts the structure, symbols, and layout to match. For specialized diagrams (BPMN, ER, sequence), use the dedicated tools at flowova.ai/tools.

How is a flow diagram different from a flowchart?

The terms are often used interchangeably. Technically, "flowchart" usually implies standard symbols (rectangles, diamonds, ovals) for process documentation, while "flow diagram" is broader — it can include data flow diagrams, system flow diagrams, and any visual showing flow of information, materials, or processes. Flowova handles both with appropriate symbols and notation.

Can I create flow diagrams for system architecture?

Yes. Describe system interactions: "User request hits Load Balancer → routes to API Server → queries Database. API Server also calls Cache for frequent lookups. If cache miss, falls through to Database." The AI creates a flow diagram showing system components and their interactions. For formal sequence diagrams, use the dedicated Sequence Diagram Maker.

How many nodes can a flow diagram handle?

The AI works best with 5-30 nodes for clear, readable diagrams. Diagrams up to 50 nodes are supported but may need manual layout adjustment. For very complex systems (50+ nodes), break into sub-diagrams — one overview diagram linking to detailed sub-flows. This is standard practice for maintaining diagram readability.

Can I use professional themes for presentations?

40+ themes available — light themes for documents, dark themes for tech presentations, colorful themes for creative contexts. One-click theme switching instantly changes the entire diagram's look. Export as SVG for infinite-resolution scaling in presentations or PNG for standard use.

What export options are available?

Free: PNG and Mermaid code. Pro: adds SVG, JPEG, WebP, and watermark-free exports. Mermaid export embeds directly in Notion, GitHub, Confluence, and other documentation tools. SVG export produces infinitely scalable vector graphics for print and web. All exports maintain the theme and styling you applied.

What is the Flow Diagram Maker?

A flow diagram is a visual representation of a sequence of steps, showing how something moves through a system - whether it is data, materials, decisions, or tasks. The term 'flow diagram' is broader than 'flowchart' and encompasses process flows, data flows, workflow flows, and system flows. Flowova's Flow Diagram Maker uses AI to generate these diagrams from plain-language descriptions. Describe what flows through your system and the AI creates a professional diagram with standard symbols, clear connections, and logical layout.

Flow Diagram Maker Features

Any Type of Flow

Data flows, process flows, decision flows, information flows, material flows - the AI adapts to whatever type of flow you describe. One tool for all flow diagram needs.

Standard Symbols

The AI uses standard flow diagram symbols: ovals for start/end, rectangles for processes, diamonds for decisions. Your diagram follows recognized conventions.

Logical Layout

Generated diagrams flow logically from top to bottom or left to right, with consistent spacing and clean connection routing. No manual alignment needed.

Multi-Branch Support

Describe complex flows with multiple decision points, parallel paths, loops, and exception handling. The AI handles all of it.

Full Editing Control

After generation, move nodes, edit labels, add or remove connections, and change the layout. Every diagram element is editable.

Export to Multiple Formats

Download as PNG for presentations, SVG for high-quality print, or Mermaid code for embedding in Notion, GitHub, Confluence, and other documentation tools.
