N8N N8N OpenAI OpenAI WhatsApp WhatsApp Pinecone Pinecone

Overview

A luxury real estate developer managing multiple resort communities across Central America needed 24/7 WhatsApp coverage for prospective buyers and residents. We built an AI concierge that understands property inventories, amenities, and policies, delivering instant answers in Spanish and English while capturing high-intent leads for the sales team.

What we implemented

  1. Vectorized knowledge base: Indexed property brochures, HOA FAQs, and policy documents into Pinecone with dense embeddings for retrieval-augmented generation.
  2. Conversation automation: Designed N8N workflows that ingest WhatsApp messages, orchestrate context retrieval, and persist chat transcripts.
  3. OpenAI agent orchestration: Crafted prompt templates and guardrails so the assistant can answer questions, hand off to humans, or schedule site visits.
  4. Lead routing pipelines: Synced qualified conversations into the CRM with tagging for community, budget range, and urgency.

Key Features

  • Multilingual responses: Automatic translation and localized tone for Spanish and English inquiries.
  • Interactive follow-ups: Workflow-driven prompts that gather desired move-in dates, financing needs, and preferred property types.
  • Continuous learning: Feedback loop that flags uncertain answers and queues documents for re-embedding.
  • Human handoff: Dynamic escalation to on-call agents with full chat context when prospects request tours or financing consultations.
