AI QA Analyst, Custom Alert Notifications, Node Search, and everything else from this month.
We're thrilled to share some exciting new features and updates on the platform. Here’s what’s new:
AI QA automatically reviews your calls and provides crucial feedback 24/7.
With AI QA, you can:
→ Surfaces patterns in your calls: Find and fix systematic issues without getting stuck on one-off bad calls.
→ Track Resolution rates across every call: Transfer rate, disconnect reasons, repeat contact patterns — by agent, call type, time period.
→ Catch what humans can't: Hallucination rate, sentiment shifts, tool accuracy — measured automatically across every call.
First 100 minutes of analysis is free.
With Alerting you can set triggers that alert you the moment something goes wrong with your agents.
Alerting lets you:
→ Know when an agent burns $100 in minutes, success rate hits 0%, sentiment drops 20% and more.
→ Delivered via email or integrate into your existing tools via webhook
→ Smart thresholds so you only get alerted when it actually matters
It only takes 2 minutes to set up your first alert.
