Jott.com - Mobile Note Taking and Hands-Free Messaging:
Jott allows you to call a phone number, and leave a voice mail message that is then transcribed into an email and sent to you or to others. Great for to-do lists and such, especially for stuff I want to remember later, but don't have time to write down at the moment. The messages come as text with a link to voice message. I'm impressed with how well it transcribes your voice message into text. With a little creative filtering in my email I can organize reminders for home and for work. Also you can easily import your address book into Jott and use the service to send messages to others just by calling a number, saying the recipients name, and then recording the message. Jott transcribes the message and sends it as an email or a text message.
