If you are like me you can't control when a great idea pops into your head. For me, it normally occurs when I am not sitting at my desk pen in hand. Jott is a voice recognition software that helps solve this problem. Just sign up for an account at www.jott.com, save the phone number you are assigned on your cell phones speed dial, and when an idea or thought arises that you are not in a position to write down, just call Jott and leave the message. Within 5 minutes it will be transcribed into text and sent to your e-mail inbox. Oh year, it's FREE too.
I Jott myself multiple times a day, with ideas, reminders, and you can even Jott others who have an account.
