Questions
Free use, editing, formats, and layouts.
Is the AI diagram generator free?
Yes. You can generate diagrams here without an account, with any layout. A free account adds 10 diagrams every month, editing, and a workspace to keep them in.
Do I need to sign up?
No. Describe your diagram and generate it. Sign up only when you want to edit or keep it: choose Edit and restyle, and the diagrams you made here move into your new account.
Can I edit the diagram after it is generated?
Yes, with a free account. Change the text, numbers, and icons, switch layouts and styles, and adjust colors and fonts without generating again.
Which file formats do I get?
SVG, which stays sharp at any size and edits cleanly in design tools, and PNG for apps that do not take SVG.
Which kinds of diagrams can it make?
Flowcharts, architecture diagrams, timelines, roadmaps, org charts, mind maps, funnels, matrices, comparisons, charts, and more: 412 layouts across 27 categories.
How does Auto choose a layout?
It reads your content and picks the layout that fits it best, then fills it with your text. When you know what you want, choose the layout yourself.
Why does the text always fit?
Every layout measures your text and sizes itself around it, so labels never overflow, overlap, or get cut off.
Can I use the diagrams commercially?
Yes, on Pro, Power, and Max. Diagrams made without an account or on Free are for non-commercial use.
