Evernote announced some significant changes to their subscription plans including the free service that they had offered for years. Last night I received a reminder email from Evernote prodding me to buy up to one of their premium plans. I deleted the email because I switched away from Evernote and started using Google Keep for all of my bookmarking and note-taking needs.
Google Keep can be used on any device on which I sign into my Google Account. As you can see in the video embedded below, you can add labels to your Google Keep notes. Those labels can also be applied to bookmarks. All Google Keep notes and bookmarks can be shared with others.
Microsoft's OneNote is another alternative to Evernote that you might consider. It works on Windows, iOS, Mac, and Android devices. I don't use it simply because I have been a Google Apps user for so long. Jeff Bradbury offers a bunch of resources that can help you learn how to use OneNote. Microsoft has published an official tutorial on how to move your information from Evernote to OneNote.
To clarify, Evernote's free plan still exists but you're now limited to using it on just two devices. For folks who use multiple computers, tablets, and phones throughout the course of a normal school week, Evernote's free plan will be inadequate.
