The Gbuddy is a chatbot that brings Google products to your IM. The chatbot runs on GoogleTalk, Windows Live Messenger and AOL Instant Messenger (AIM). It's possible to search for Youtube movies, maps, images or plan a trip with local public transportation (US).
A chat bot is a humanlike conversational character.
Its conversational skills and other humanlike behaviour is simulated through artificial intelligence.
It often acts as a virtual assistant and it can have its own visualisation through an avatar
or it is faceless. We expect that through the years every conversational chat bot will grow into a real virtual human.
