Key Metrics

  • Net Sentiment Score (NSS)
    The average sentiment across a conversation or set of conversations.
  • Sentiment Shift Score (SSS)
    Measures how sentiment changes throughout the chat (e.g., going from frustrated → reassured).
  • Lowest Sentiment Point
    Highlights the most negative user message with its sentiment score and detected emotion.
  • Actionable Recommendations
    AI-powered suggestions for next steps to resolve issues and improve customer experience.
