## Summary

Nizzy measured 12 weeks of Instinct text messages, logging 185 messages from himself and 375 messages plus 88 tapbacks from the assistant. He says the assistant corrected a wrong insurance question within a minute and enrolled him in a dental plan 22 minutes after his first text. He describes it as an assistant that asks for approval before submitting or paying anything and sends sensitive details through secure links instead of chat.
