Frequently asked questions
Is this mind map maker really free?
Yes. There is no sign-up, no watermark on the screen and no limit on how many maps you make. Exported images carry a small "Made with DioxAI" credit line.
Is my data private?
Your text stays in your own browser the entire time. Maps are saved only in your browser's local storage, and nothing is ever sent to or stored on a server.
Can I use AI to create a map?
This tool does not call an AI itself. Use the Copy AI prompt button, paste the prompt into any AI chat like ChatGPT, Claude or Gemini, then paste the outline it returns back into the box. Your map builds instantly.
Which file formats can I export?
PNG and SVG for images, plus Markdown and JSON if you want to reuse the outline elsewhere. You can also copy the map straight to your clipboard or upload a TXT, Markdown or JSON file to start from.
Does it work on my phone?
Yes, fully. Pinch to zoom, drag with one finger to move around, and tap any bubble to edit it directly on your screen.
Are my saved maps only on this device?
Yes. The My Maps list uses this browser's local storage, so your maps will not appear on another phone or computer. Use Copy Share Link or Download JSON if you want to move a map somewhere else.
