From two sentences to a 12-node flowchart

The kind of input most people actually type.

Input

Generated flowchart filling in the skeleton with labeled process steps and decision branches

What the AI produces

The AI inferred that "any approver rejects" means each step has its own reject branch, not just one global one. Multi-threshold routing like this would take 5+ minutes to draw manually in draw.io.

What does Flowova's flowchart maker actually do?

Describe a process — even loosely — and you get back a flowchart with proper start/end ovals, decision diamonds, and labeled edges, laid out automatically. From there it is a real editor: 40+ themes, drag nodes around, talk to the AI Chat Agent to refine ("merge steps 2 and 3"), and export. PNG export is free; SVG, JPEG, WebP, and Mermaid export are part of the Pro upgrade. There is no shape palette to learn — the assumption is you know what your process looks like; the tool handles drawing it.

Create a Flowchart with AI in Seconds

1

Describe Your Process

Type the flowchart you want. Any level of detail works — "approval flow for expense reports" gets a starter; "manager reviews under $500, director reviews $500-$5000, CFO reviews above" gets a fully branched chart with three decision diamonds.

  • Plain English (or any of 11 supported output languages)
  • From single decisions to multi-branch processes
  • Same entry point for paste, file, URL, or image
2

AI Generates Your Flowchart

The AI selects appropriate shapes (rectangles for steps, diamonds for decisions, parallelograms for I/O, ovals for start/end), assigns swim-lanes if you mention roles, and lays out the diagram with proper spacing.

  • Start/end ovals, decision diamonds, labeled edges
  • Auto-layout via Dagre, not random placement
  • AI Chat Agent (Pro) refines without re-prompting
3

Edit and Export Free

Edit any node inline, drag to reposition, recolor with one of 40+ themes, or use the AI Chat Agent to make changes conversationally ("merge the two review steps into one parallel review").

  • 40+ themes for slide, doc, brand, or audit context
  • PNG export is free; SVG and Mermaid are Pro
  • Public read-only share links for stakeholder review

Flowchart Maker Features

Column of five input source icons (text, file, URL, image, AI chat) merging into one flow rectangle

Five Input Surfaces

Paste text, drop a file, paste a URL, upload an image, or talk to AI Chat Agent — same starting point regardless of source.

Dagre Auto-Layout

Nodes positioned by Dagre, not randomly placed. Decision diamonds align vertically, parallel branches render side-by-side, no overlapping edges.

40+ Themed Palettes

Vibrant for slide decks, Forest/Ocean for ops docs, Graphite for technical specs, Midnight for code, Wine for branded content — switch in one click.

Three arrow styles stacked vertically: smooth, straight, and bezier

Three Edge Styles

Smoothstep (default), straight (for technical diagrams), or simplebezier (for organic flows). Toggle per diagram, applied globally.

Fan of five file format tags: PNG, SVG, WebP, JPEG, MMD

Multi-Format Export

PNG free for sharing and slides. SVG, WebP, JPEG, and Mermaid (Pro) for vector-quality docs, blog images, and round-trip with code-as-diagrams workflows.

Single pen-drawn chain-link icon with a view-only sticky-note label beside it

Public Read-Only Links

Generate a shareable URL — recipients see the diagram in the browser without an account. Revoke anytime from settings.

When to use the flowchart maker

Use this tool for

  • The diagram you want is 'just a flowchart' — boxes, diamonds, arrows — and the audience doesn't care which formal notation.
  • Business processes, approval routing, and decision logic where the steps and branches are the whole point.
  • First-draft diagrams that you'll iterate on with a teammate or stakeholder before publishing.
  • Documentation flowcharts for SOPs, training material, and customer-facing how-to guides.

Use a different tool for

  • Database schemas — ER Diagram Generator handles cardinality and foreign keys correctly.
  • Cross-team workflows where roles and handoffs are the focus — Swimlane Diagram Maker draws lanes natively.
  • Diagrams that need a huge stencil library or unusual custom shapes — draw.io's free shape catalog is unmatched for that.
  • Real-time collaborative editing with multiple cursors on one canvas — Lucidchart and Miro are built for that workflow.
