The chat pillar covers web widget and SMS. It answers from your own documents rather than a generic model prior, qualifies the enquiry against the same rules the voice agent uses, books where booking is possible, and escalates with the full transcript attached.
Price research, document requests, order and appointment status, and anything the visitor would rather not say out loud. Chat also wins on cost per conversation by a wide margin, which makes it the right first build for businesses whose enquiries are mostly informational rather than urgent.
Most businesses run a web widget and ignore SMS, but SMS is where confirmations, reschedules, and no-show recovery actually happen. The same agent and the same knowledge base serve both channels, so adding SMS after the widget is configuration rather than a second build.
