Jreepad is an excellent free "personal database" program - it's a great way to organise all your personal notes, thoughts, tasks, recipes, memories...

Jreepad is originally based on Treepad Lite, an excellent free program which is only available for Windows and Linux. Jreepad has gradually grown to provide more functionality than Treepad Lite, but its files are still compatible with the original Windows software.

Please note that Jreepad is not directly affiliated with Treepad - it's an independent project.
