| Description | Sierra is a conversational AI platform that lets companies build and deploy autonomous AI agents for customer experience—handling support, driving revenue, and taking backend actions across chat, SMS, WhatsApp, email, voice, and ChatGPT. Aimed at mid-market and enterprise CX and operations teams, it stands out for its outcome-based pricing (you pay for resolved outcomes, not seats) and Ghostwriter, an agent-building agent that turns SOPs, transcripts, and plain-English goals into production-ready multilingual agents. | Waplify is a WhatsApp marketing, sales and support platform built on the official WhatsApp Business Cloud API. It works with an existing WhatsApp number and says it adds no markup on Meta's message rates. |
