Helps you keep track of your quotes and stuff
CiteMe is similar to bookmark but with selected texts! With customizable shortcuts, you can store any quote you'd like and access them conveniently just by pressing the extension's browser icon or going to the options page. You can also do a live search of your quote.
Note: It requests permission to access your data and browsing activity to access the URL and selected quotes of your pages to save!
