You must purchase basic in order to get any of the other modules (like Studio for digitizing) for permanent use. Embird offers a free trial for all of the modules they offer so you can play with it. However, I don't think you can save anything you do in the trial (I did not try when I did the trial).

I did the free trial Embird and couldn't figure out what to do in it until I purchased the Basic and Studio, & then a set of lessons and last evening I did my first design!!! I am sooooo tickled, once it is explainrd (to me) I do well. The lessons I am doing so good are on Stitches in Motion & you only buy what you need, you do not have to buy all lessons. She does her lessons as if you know nothing! And I know nothing!!! Hahaha! Hugs, Judy
