Notes are stored in books which can be nested to organize ideas hierarchically, and there is no limit to the number of books or how deeply they are nested. Rich-text formatting and multimedia such as images and video are all supported.


Emails and calendar events can be anotated with notes. These notes appear both in the Email and Calendar applications with the message or even they were added to as well as in the Notes application. Notes are linked to the message they are associated with, making it quick and easy to go from notes to the relevant message with a single click and then back again.

Search and Tagging

Never lose a note again. Notes can be found using the full-text search, making it easy to find them even across multiple notebooks. Notes may also be tagged and filtered using Kolab's unified tagging system which allows the same tags to be used on emails, events, tasks, etc.


Notebooks can be shared between users with fine-grained access controls. This allows people to work together, with some able to modify or delete notes while others may only view them..


Kolab lets people take their notes with them. In addition to access via the Kolab Web Application or native desktop apps, notes can be synced with mobile applications for use on the go.
