Honestly the worst, slowest, hardest to use platform I have ever used
It was very slow, the box that comes up when you hover over notecards didn't go away, you had to wait for about 2 seconds after pretty much every action you took.
How I Use It
We used it to write a research paper on Ancient Egyptian Technology. It was extremely slow, confusing, irritating, and just generally bad for even a class of 20 7th graders.
