Diigo

Diigo is like a special marker or highlighter that you can use online. You can use it to mark important information and save it for later. Just like when you use a marker on paper to remember an important part of a book or text, Diigo lets you do it on websites and web pages.

Diigo also lets you add notes to your highlights, so you can remember why you marked something as important. And if you want to share your notes and highlights with someone else, you can do that too.

Overall, Diigo helps you keep track of important information you find online and share it with others.
