One Dash Zero routes voice calls, web chat, SMS, and WhatsApp through a single AI agent trained on your business knowledge, hours, and booking rules. Every interaction—regardless of channel—flows into a unified contact log that your team can reference when taking over a conversation. Rather than weeks of integration work, the onboarding is a five-minute web wizard with no developer involvement required. Calendar sync is optional OAuth; everything else runs out of the box. The voice layer runs on ElevenLabs infrastructure, and the pricing model is a flat monthly subscription with usage allowances, so you're not constantly negotiating per-seat or per-minute costs as your volume shifts. The tool is built for small and mid-sized businesses where channel fragmentation is a real problem but a 50-person implementation team isn't realistic. A free trial is available if you want to test the experience before committing.
