Evi is now True Knowledge are the creators of Evi, the digital personal assistant currently available for both iOS and Android.

Evi is the successor to the True Knowledge Answer Engine and utilises natural conversational input to allow a user to ask for information or perform tasks by speaking in a totally natural manner without pre-programmed voice commands.

Evi utilises a variety of information sources including her own database of nearly a billion facts as well as numerous external resources.

True Knowledge’s technology is non statistical, meaning that it knows when it cannot understand the user’s question or provide an answer. This it allows it to complement existing search technologies producing its direct answers when it can and other results such as standard internet search results when it cannot.
