The Fastrill difference

Intent over
keywords.

Every other tool matches words. Fastrill understands meaning — and responds like your best sales rep would.

  • 🧠
    Real-time intent detection
    Messages are analysed semantically, not by trigger words. Multi-intent messages get multi-part answers.
  • 😊
    Sentiment awareness
    Frustrated customers get empathetic replies. Excited customers get enthusiastic ones. Context always matches.
  • ⚡
    Sub-second response
    Replies go out in under 2 seconds. No customer left waiting, no lead going cold.
