Frequently asked questions

Is FreeDiagram really free?

Yes — completely free, unlimited, with no signup, no credit card, and no watermark. The site is funded by ads, so it stays free for everyone.

Do I need an account?

No login, no sign-up. Just open the page, describe your diagram, and generate it. Nothing you type is saved.

What can I make?

25+ kinds of diagram, and we pick the right one for you: flowcharts, mind maps, charts, timelines, org charts, family trees, ER diagrams, and many more.

Do I need design skills?

Not at all. If you can describe it in a sentence, you can make it — there's nothing to drag, draw, or line up by hand.

Can I download or edit it?

Yes — download a sharp SVG or a high-resolution PNG, or copy the diagram source to fine-tune it and draw again.

Is my data stored?

No. Your prompt and the diagram are not saved on our servers — each request stands alone, and closing the tab leaves nothing behind.
