The 8 channels are voice, SMS, WhatsApp, web chat, Gmail, Outlook, Slack, and Microsoft Teams. Agents run on three technologies. Conversational AI agents hold natural, multi-turn dialogue to qualify leads, answer questions, and collect details.

Setup starts from a ready-made template, or the AI Concierge builds the agent from a plain-language description. No developer is needed. The 2,700+ systems include CRM, scheduling, ERP, helpdesk, and ATS apps, with native Google Sheets and Slack connections, so agents read and write live data. Pricing is usage-based with no subscription and no per-seat fee. Pay as You Go is free to start with 5,000 credits on signup, credit packs from $10, credits that never expire, and up to 5 user seats.
