Here's the thing. Information is just one part of knowledge. There is also the judgement to place that information into a framework, there are patterns to recognize, there are dots to connect. So, as you read through a source document in Pandexio, you snip out a bit of knowledge, a unit of learning, you give it a good, clear statement, add some tags and a note, and then you have, what we call a HYPERSNIP.
The document is still important, but now mostly as the context for your knowledge, the source. Once you pull that bit of knowledge out, let's focus on all of your bits of knowledge, rather than having to walk back into every document. That is the basis of Pandexio: pull the knowledge out, but keep the context.
