A big thanks to Randy Lindquist, Tech Director at MAISD, for this tip!

Cobocards, short for Collaborative Cards, is a free online tool that allows users to create virtual flash cards for whatever they need. After creating an account you can print them and study offline, edit them again and again, compare with older versions, check the status of your knowledge, upload pictures and graphs, share your flashcards with friends, set a deadline for exams – everything you can do with traditional flash cards – and more.

Create Flashcards
Create your own flashcards with two clicks. You can use different styles (bold, italic, red/green colour, underline). Add pictures to your cards easily.

Study Flashcards
You can study your cards alone or online with your friends. Just use Skype or the integrated chat functionality and see how easy it is.

Print Flashcards
Print individual flashcards or all of them in two steps and learn them offline wherever you are.

Work with a Team
You can comment on each flashcard, track the status of your knowledge, track changes, study online with friends and send messages to them.

Publish Flashcards
You can publish your flashcards. Everyone who receives the link to your cards can import them to their account.

Check out the Cobocards site for a virtual tour and find answers to FAQs on the Cobocards wiki. Developers have plans to introduce a professional version with more functionality for a small fee but say the basic version will always be free.
