Think different
Why would I use it? Everything is fine I already work with

Treegonizer products are centered around Notes and Docs you create which are represented by a tree (Treeview).

The Notes and Docs functions are extended with other functions (depending on the product you choose) with integration to Office files, Multimedia, Contacts, Email, Web browser  and Calendar.

All data created or imported is stored into a superfast single file which you can share secure with others.

All objects and data can be grouped, related, tagged and hyperlinked to each other.

Where OneNote and EverNote work with loosly coupled integration to office suites (like Outlook combined with Microsoft Office) is everything tight integrated into a single user interface in DocOne and FileOne. No need to mess around with multiple windows and programs. And where OneNote and EverNote become slow when used with huge amounts of Notes and complex structuring, are DocOne and FileOne extremely fast.
