He and his team of computer engineers at Expect Labs, a San Francisco start-up, have spent the past two years building an "anticipatory computing engine" - a platform for applications that predicts what people want or need before they explicitly ask or search for it.
Its first app for the iPad is MindMeld, a group voice and video-calling app that analyses what's being talked about in real-time and "predicts" the type of information participants may want or need, pushing it to their tablets within seconds.
For example, let's say, several co-workers are planning to meet up for bar snacks after work.
Depending on what types of food, drinks and possible meeting places are mentioned, MindMeld "listens" in the background and pulls up pertinent restaurant suggestions, reviews, maps, images and phone numbers using data from across the web and social networks.
The app is also designed to counter forgetfulness by delivering background information about the people on the call or those being discussed.
The core technology allows users to "just glance down and jog your memory so you don't look stupid in the conversation," said Mr Tuttle, co-founder and chief executive of Expect Labs.
It "annotates and bookmarks the most important parts of a conversation," he added.
The entrepreneur holds a PhD from MIT's Artificial Intelligence Lab, and in 2004 helped create Truveo, a video search engine which he later sold to AOL.
Mr Tuttle said the new app was due for release in October and would initially only feature voice calls. He intends to add video before the end of the year.
"Ten years from now, this is going to be standard on every phone call," Mr Tuttle told the BBC.
That could be interesting running when your having a beer session with your mates.
On a serious note though....Big Brother or what. This will bring a whole new way of spying on people.
Life is like a penny, you can spend it on what you like, but you can ONLY spend it once.
