When Siri arrived on the iPhone 4S I thought to myself, who else could do this? It would need to be a search engine with natural language processing, but also behave in the manner of artificial intelligence and respond to voice recognition. One company that sprung to mind was True Knowledge. I pinged them. Are you working on a Siri type application, I asked? Interesting question, was their response. And then they went quiet.

Now they can reveal what they’ve been building. Evi is a new iPhone (iTunes link) and Android app in Beta (link) which might just give Apple’s Siri a run for her money.
