The AI diagram generator — approval workflows, swimlane diagrams, org charts, project timelines, customer journey maps, process flows, BPMN-inspired layouts, and 14 more diagram types. Fully editable, not locked images. flow-chart.io turns ideas, documents, and plain-language descriptions into polished, presentation-ready diagrams.

Paste a document, describe a workflow, or type a rough outline. flow-chart.io generates a polished diagram as a live scene graph — every node, connector, label, and lane is editable. Refine by chatting, track versions, or export to SVG, PNG, PDF, or Mermaid.

Your diagram is no longer a one-shot output.

Conversational refinement — chat with the diagram to add, remove, rename, regroup, or restyle elements without starting over.
Version history — browse earlier drafts and see what changed.
GitHub scanning — connect a repository and scan the codebase to ground your diagram in the system you actually run.

One prompt gets you started. A living, editable diagram gets you to the finish line.

Every kind of professional diagram.

flow-chart.io covers 17 diagram domains — business process, IT and systems architecture, cloud architecture, DevOps, security, data, AI/ML, network, org, finance, product, and more. Each domain includes a built-in knowledge panel, notation guidance, and notation checks.

From rough idea to shareable diagram in five steps.

Enhance — start with a sentence, document, conversation, or repo. flow-chart.io turns rough input into a stronger diagram brief.
Generate — get a polished diagram grounded in your selected domain and notation.
Refine — chat with the diagram to add, remove, rename, regroup, or restyle elements.
Review — browse versions and compare changes.
Share — export to SVG, PNG, PDF, Mermaid, or re-importable JSON.

AI that knows the standards, not just the shapes.

Templates and best-effort checks are informed by common notations and frameworks (BPMN-inspired process maps, C4, ArchiMate, UML-style diagrams, and more). After generation, an AI audit advisor can surface likely issues as actionable suggestions — for example, "this BPMN gateway has unlabeled exits" or "this C4 container diagram is missing a trust boundary." Pro and Team plans include the full audit suite.

Frequently asked questions

Is flow-chart.io free to use?: The free plan includes 4 AI credits a month (one flowchart) and 1 saved diagram. Downloads (SVG, PNG, PDF, PowerPoint) need Pro.
What makes flow-chart.io different from other AI diagram tools?: flow-chart.io generates an editable scene graph — every node, connector, lane, and label is a typed object you can move, restyle, and reconnect without starting over.
Does flow-chart.io support BPMN 2.0?: The business process domain can generate BPMN-inspired elements such as pools, lanes, tasks, gateways, and message flows.
Can I generate C4 model diagrams with AI?: Yes. The IT & systems architecture domain supports the C4 model across Context, Container, and Component levels. Each level generates appropriate abstractions: Person and System nodes at Context, Container nodes with technology labels at Container level, and Component nodes at the deeper level.
What export formats are supported?: All diagrams export to SVG (vector, scalable), PNG (2× and 4× pixel density), PDF (print-ready), JSON (canonical scene graph, re-importable), and Mermaid (.mmd format). Exports are derived directly from the scene graph — not screen captures.
Can I upload an existing diagram and make it editable?: The image-to-diagram feature accepts supported raster images and attempts to reconstruct them as editable scene objects. Results vary with image quality and complexity and require review.
What AI standards does flow-chart.io support?: The generator includes templates and best-effort checks informed by several common diagram notations and frameworks.
How does the standards audit work?: After generation, an AI audit advisor can flag likely issues against the relevant notations for its domain and surfaces them as actionable suggestions — for example, "this BPMN gateway has unlabeled exits" or "this C4 container diagram is missing a trust boundary." Checks are advisory. They are not a BPMN, C4, or ArchiMate certification. A qualified person should review the diagram. Pro and Team plans include the full audit suite.
