Yakkle is Instant Collaboration.
You may have used an instant messaging tool like AIM or Yahoo Chat or Google Talk and know that you can send text messages to your family, friends, co-workers and associates. Yakkle does instant messaging too, but it also allows you to use your PC to transmit your voice to your friends and to share your desktop with them all from within a single application. It’s kind of a triple-play. Now you can connect with anyone on the internet, send them a “hi”, speak with them using superb sound quality and show them anything you have on your PC, like photos or documents. You can even let them control your mouse and keyboard from their computer.
You need a PC running Windows XP or Windows Vista and a high speed network connection. To use the voice options, you should also have a USB Headset or a PC microphone and set of speakers.
