Tools that work for your workflow.

Everything you need to sketch, structure, and share a diagram, built to be fast and trustworthy.

Text to Flowchart

Flowchart Maker

Sketch flowcharts and diagrams with connectable shapes, then export as a PNG or PDF you can drop straight into a doc.

Private by design

For every tool but two, there’s no server in the loop — diagrams are built and exported on your own device using your browser’s built-in engine, never uploaded or seen by us. The two exceptions are Text to Flowchart and Flowchart Scanner, which send your text or image to Claude (Anthropic) so it can interpret it.

// runs entirely in your browser
async function exportDiagram(canvas: Canvas) {
  const result = await renderLocally(canvas);

  // nothing is ever sent to a server
  return result;
}

Frequently asked questions

Do you store or upload my diagrams?
For every tool except Text to Flowchart and Flowchart Scanner: no. Everything is built and rendered locally in your browser using JavaScript, and nothing is sent to a server. Those two are the exceptions — they send your text or image to Claude (Anthropic) so it can interpret it into a diagram.
Is FlowchartLab really free?
Yes. Every tool is free to use, with no sign-up, watermark, or diagram-count limit.
How does Text to Flowchart work?
You describe a process in plain language, and it's sent to Claude (Anthropic) to identify the steps and decisions and turn them into a flowchart, which then opens in the normal editor for you to adjust, restyle, or export.
How does Flowchart Scanner work?
You upload a photo or screenshot of an existing flowchart — hand-drawn, whiteboard, or from another tool — and it's sent to Claude (Anthropic) to read every shape, label, and connection and rebuild the same diagram, which then opens in the normal editor for you to adjust, restyle, or export.
Can I export my flowchart?
Yes. Every diagram can be exported as a high-resolution PNG or a PDF, ready to drop straight into a document or presentation.
