Active since March 30, 2012, when the Siri craze just began, PAT became one of the largest Siri servers on the internet. Available for free, anyone with an iOS device was able to connect and have instant access to a personal assistant. We knew, at some time, people would upgrade their phones to devices that natively support Siri making PAT obsolete. The time is now. More people own devices that have Siri built in than devices that do not. We will miss PAT and hope you will too.
