We have seen Siri clones in the Android Market trying to pass themselves off as the real thing, and some Siri alternatives making their way to the Windows Phone Marketplace. Evi, on the other hand, might actually be the first true Siri competitor/alternative for Android and non-iPhone 4S iOS users.
Available on the App Store for 99 cents and free to Android users on the Android Market, Evi is the work of True Knowledge and its “core semantic search technology” better known as The True Knowledge Answer Engine. The 99-cent price tag on iOS is apparently to cover the cost of using Nuance voice recognition (the same voice recognition tech as Siri), which is not used in the Android version.
The app’s iTunes page explained Evi is capable of returning local data for the United Kingdom (along with the United States), which has been a complaint from U.K. Siri users since the iPhone 4S launch. According to TechCrunch, the app uses “an ontology of tens of thousands of classes into which” every possible user command can be recognized. True Knowledge said the app contains “almost a billion ‘facts’ (machine understandable bits of knowledge)” with the ability to infer trillions if necessary. It also reportedly uses all the expected sources, such as local results from Yelp, third-party websites, traditional web searches, and APIs.
While as of yet Evi is incapable of integrating with Calendar and Reminders like Siri, TechCrunch pointed out it sometimes provides more accurate and useful results for certain types of questions. Siri requests to search the web for an answer when users ask certain questions, such as “How do I make apple pie?” Evi, however, would provide a list of recipes with relevant links to that specific question. TechCrunch highlighted another example where Evi excels:

Ask “Who was President when Queen Elizabeth II was born”. Siri is unable to provide an answer and suggests performing a web search. Evi determines who Queen Elizabeth II is, when she was born, the dates when she will have been a teenager and then compares this against which US presidents were in office over that time, delivering the results of both serving US presidents during those years. Not bad huh.
