While Google Drive lets you store your documents, Evernote Webexcels at keeping everything organized. Create Notebooks based on subject or task, and then fill them up with Notes. Your Notes can be anything, including written missives, images, PDFs, and webpages.
Best of all, Evernote gives you numerous ways to put Notes into the tool. An Evernote plug-in lets you add links directly from your browser, and a custom email address allows you to forward messages to Evernote from whichever device or email client you’re using. It’s free for the basic service, and $5 a month for Premium.
