Last week, "Evi," a voice-powered artificial intelligence system that's awfully similar to Apple's Siri feature on the iPhone 4S, was released into the App Store (link). The app functions similar to Siri in the way that information is inputted and displayed to the user. The app is powered by Nuance speech technologies, just like Siri as well.
Some of Evi's features are listed below:
- Voice or text input - Chat to Evi in plain English and she will understand
- Local information for UK and USA - Shopping, news, dining and more. Evi knows where you are and gives answers based on your location
- One tap words - Allowing you to build your question super-fast
- Built in browser - No need to swap to a different browser, view web links within Evi's app
- A learning and adapting intelligence - Rate Evi’s answers to help her learn more about the world
- More than a search engine - Evi takes the searching out of search, able to review and compare nearly a billion facts from her database to give you exactly what you need
Evi, however, is not integrated into stock iOS apps like Siri is.
The app is available for $0.99 and works on any iPhone, iPod touch, or iPad compatible with iOS 4.0 or better.
