About the tool
What is FlowchartLab?
FlowchartLab is a free online flowchart maker. You can build a flowchart, org chart, decision tree, mind map or process diagram in your browser, with no account to create and no software to install. Exports have no watermark.
Start from a blank canvas or pick one of the ready-made templates, then change the text, colours, fonts and shapes. Or describe a process in plain language and the Text to Flowchart tool drafts the diagram for you to edit. When you are done, export a PNG for slides and documents or a PDF for printing, on a square, widescreen or vertical canvas.
Everything you draw stays in your browser. The only tool that sends anything away is Text to Flowchart, which passes your description to an AI model (Claude by Anthropic) so it can work out the steps.

Open the editorPrivate by design
For every tool but one, 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 one exception is Text to Flowchart, which sends your text 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;
}Questions
Frequently asked questions
- Do you store or upload my diagrams?
- For every tool except Text to Flowchart: no. Everything is built and rendered locally in your browser using JavaScript, and nothing is sent to a server. Text to Flowchart is the exception — it sends your description to Claude (Anthropic) so it can interpret it into a diagram.
- How do I make a flowchart online?
- Open the Flowchart Maker, pick a template or start with a blank canvas, click shapes to type your steps, connect them with arrows, and export a PNG or PDF. You can also describe the process in plain language and let the Text to Flowchart tool draft it for you.
- Do I need to download or install anything?
- No. FlowchartLab runs in your web browser, with no software to install and no account to create.
- What kinds of diagrams can I make?
- Flowcharts, org charts, decision trees, mind maps, process flow diagrams, swimlane diagrams, fishbone diagrams, timelines and Gantt charts. There are free templates for each, and you can start from any of them.
- Is FlowchartLab free?
- Yes. Every tool, every template, unlimited flowcharts and exports, no watermark, no account, no subscription.
- 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.
- 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.
