I was impressed with the demo video. I was impressed with the live demo on the app's homepage. I subscribed. But it is so slow and the actual app was clunky and refused to enter much of the dictated text that I gave it (even though it seemed to be recognizing what I said): the words appeared on the screen, then they disappeared. I had both the speed problem and the recognition problem on both of the latest versions of Firefox and Safari, even though my connection is ~ 620 Mbps up and down. I canceled my subscription within about 10 minutes. Oh, I should also add the following feedback: * The homepage promises that your subscription will include support, but even when you're subscribed, the support button is greyed out. * There is no way to manually enter or edit the titles of your documents. I'm disappointed, because I was very excited about this.
