Describe it. Get an editable diagram.

Workflows, swimlanes, org charts, and more — live scene graph, not a locked image. Standards checks are advisory.

Describe any process, workflow, or organizational structure. flow-chart.io generates a polished, domain-aware diagram as a live scene graph — every node, connector, label, and lane is editable. Refine by chatting, paste documents directly, or export to SVG, PNG, PDF, or Mermaid.

Describe it. Get an editable diagram.

Workflows, swimlanes, org charts, and more — live scene graph, not a locked image. Standards checks are advisory.

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, see what changed, and restore the version that tells the story best.
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 best-effort standards checks (advisory, not a certification).

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, compare changes, and restore the right draft.
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." Checks are advisory, not a certification. Pro and Team plans include the full audit suite.

Frequently asked questions

Is flow-chart.io free to use?: Yes. The free plan includes AI credits/month (~5 standard diagrams), up to 3 saved projects — no credit card required.
What makes flow-chart.io different from other AI diagram tools?: Most AI diagram tools generate a raster image you cannot edit. flow-chart.io generates a fully 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. Its automated checks are best-effort and do not certify BPMN compliance.
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. Generated output is not a certification and should be reviewed by a qualified person.
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, not a certification. Pro and Team plans include the full audit suite.
