Jarnal – An Open-Source Digital Note-Taker and PDF Annotator

Jarnal is a Java-based digital note-taking and sketching app you can use to create journals, presentations, and annotations on documents including PDF using a stylus, mouse, or keyboard.

It is reminiscent of Microsoft Windows’ Journal, Mimeo whiteboarding, and Palm note-taking applications

Features in Jarnal

  • Freeware: Notelab is free for everyone to download and use
  • Open Source: Contribute to the source code. See the Release Notes

Jarnal is not perfect and there are some missing features like support for other graphical export formats besides JPEG and PDF, resizing images using the text function, adding information like authorship and bookmarks to the undo stack. The beauty of open-source software is that where there’s a will, there’s a way. Expect to see improvements to the app soon.

Installing Jarnal is easy. As long as you have Java running on your computer, you can download and unzip jarnal-install.zip package and make jarnal.sh executable and run it.

$ wget http://www.dklevine.com/general/software/tc1000/jarnal-install.zip
$ unzip jarnal-install.zip
$ cd jarnal-install
$ jarnal.sh

On Debian and Ubuntu, you can download the .deb package and install it.

According to the developers,

There is also a commercial knockoff of Jarnal called PDF Annotator – for $50 you can enjoy a subset of the capabilities that Jarnal provides for free.
