This AI Sales Agent Sells for You 24/7 (Voice + Text + RAG)
If you want to learn how to build these, I have a new course coming in the NCA Group. This AI RAG sales agent handles calls, texts, and emails automatically—remembering every conversation across channels so prospects never repeat themselves. In this video I'll show you how to build a complete AI sales system that works across WhatsApp, SMS, Telegram, email, and voice. You'll see cross-platform session management, RAG database integration with Supabase, automated lead qualification, and intelligent call booking. I'll walk through the real engineering decisions behind each feature: why I use three separate agents, how session IDs transfer between channels, Airtable integration for CRM, and how the voice agent picks up mid-conversation. Plus automatic video transcription for your knowledge base and smart spam filtering. If you want to scale your sales process with AI that actually remembers context, this is how you build it.
