A personal information manager (PIM) is something to help you keep track of a lot of important stuff. It can be software on your computer, or a website you use. It can help you remember important events, such as birthdays or anniversaries. It can store contact information such as phone numbers and email addresses. It can keep track of appointments or tasks you need to do, and even remind you when they're coming up. You can also save notes and ideas in a PIM. With all this help, you can stay organized and be sure you don't forget important things!
