Questions
How do I make a mind map from a PDF?
Upload the PDF above and press Make a mind map. The AI reads the file and builds a tree: the main idea at the root, the big topics as branches, and key details under each topic.
How big is the map?
Up to 16 ideas per map, so it stays readable on one screen. For a long book, upload one chapter at a time and make a map for each.
Can I move around the map?
Yes. Drag to pan, zoom in and out, and fold a branch to hide its details while you look at the rest.
Can I export the mind map?
Yes. Download it as Markdown, or as OPML, which many mind map and outline apps can open.
Does it work on a scanned PDF?
Yes, for a small number of pages. The AI reads the page images. A long text PDF is read up to a page limit, and the result says when it stops.
Is it free?
Yes, no account and no card, with a small daily limit on free runs. Sign up free to keep the map with flashcards and a quiz from the same PDF.
