# Outsolvi end to end: tracking, follow-up and AI with Nate Summers

> Forty-five minutes on the whole system, for teams deciding whether Outsolvi replaces more than one tool. We start where a send begins and follow it the whole way: the plugin inside Outlook or Gmail, confidence scoring separating people from scanners and Apple pre-fetch, hot-lead detection surfacing who to call, sequences that stop dead on a reply, reply sentiment, the shared team view, and how engagement reaches your CRM. Best booked when you already have a stack and want to know what it collapses into. Bring the tools you currently pay for and we will be straight about which ones we replace and which ones we do not.
