8 Best Free and Open Source Linux Personal Information Managers

A personal information manager (often known as a PIM tool) is a type of collaborative software that can help you manage your life by offering personal organizing functionality. This type of software enables you to more efficiently manage and plan your business and personal life by keeping track of contact information, appointments, tasks, diaries, to-do lists, and birthdays.

Some PIM tools offer additional functionality including project management features, email, and RSS feeds, offering a more integrated solution to your needs and requirements.

A good PIM is a valuable aid in planning. Computers are ideal for manipulating information as they allow modifications to be made without erasing or rewriting. As plans are subject to frequent modification, planning software can be very desirable. PIMs allow users to centrally collate different types of data, and to have access to that data much more easily than traditional methods.

Linux has a large number of PIM tools available, some of which offer innovative ways to consolidate information both for private and business use.

To provide an insight into the quality of software that is available, we have compiled a list of 8 of our favorite PIM tools. Hopefully, there will be something of interest for anyone who wants to manage and track their personal information, and to help add some structure to their daily life.

I’m surprised that you mention TreeLine but fail to mention Cherrytree by Giuseppe Penone, which is by far a better product than TreeLine.

While TreeLine is OK, I think you should try Cherrytree by by Giuseppe Penone. It does far more than TreeLine, and does it better. I use Cherrytree for all my writing needs – not just notes.
