PDF to Mind Map

It takes a document and returns its content as a mind map — one centre with branches radiating out, so a long read becomes something you can take in at a glance. Where tools differ is what the branches are built from: most rebuild the contents page, which is a layout decision rather than a reading of the document.

Yes — one document costs nothing. Where the paid plans come in is volume and consistency: a folder at a time, the same depth and naming across a whole reading list, and the run kept so later documents match.

Yes, and length is the case it is meant for — a short document rarely needs a map. What changes with a long one is not whether it can be read, but how much has to be left out, because a map of everything is just the document again in a worse shape.

Not at the moment. It works from the text in the file, so a scanned page that is really a photograph, or a picture whose meaning is in the picture, sits outside what it reads. If your document is text-based but has diagrams in it, the text gets mapped and the diagrams do not.

Most tools convert the same way for everyone, and charge for the fiftieth document what they charged for the first. Here what you settled on — how deep, what gets left out, how branches are named — is kept and reused, so working down a reading list costs less as you go rather than the same each time.
