that's exactly what it is!
My grandma thought it would be a good investment for me in school, and to finish my books. I really did not want one because I know it can't fix grammar. Right now I actually have to say the words for the punctuation. But I've been using it for a few hours now, an I'm actually starting to get used to saying the words instead of typing them. I'm starting to find it easier for me to figure out where comma goes when I stop talking rather then when I'm typing.
I still have some bugs to fix out with it. Because it needs to calibrate my voice and speech for little bit before it's completely accurate. But so far so good. One really good thing about it, is it corrects mistakes made previously, later on. For example he couldn't understand the word Matty. Until I deleted the word it had instead and inserted Matty. Now on every time I say Matty, it comes up as Matty. Pretty cool right?
