| Dimension | Voice AI | Video AI |

| Interface | Phone / audio only | Visual presenter + screen |

Why video wins for product demos
Three structural reasons:
- Demos are visual by definition. Buyers need to see UI, workflows, features.
- Voice can describe; video shows. "Look at this dashboard" is what converts, not an audio description.
- Attention holds longer with video. Visual + voice engagement > audio-only.
Naoma, Supersonik, Karumi all chose video-first for this reason. Try Naoma.
When voice AI still wins
Three legitimate use cases:
- Pre-demo phone qualification - 10-minute discovery calls where visual isn't needed.
- Inbound phone triage - AI answers, qualifies, routes. 11x Julian fits here.
- Post-demo follow-up - voice-only check-ins for existing customers.
SalesCloser ships phone + video + demo combined ($499-$2,999/mo) - good for teams wanting all three in one vendor.
