Cendra is an AI-powered guest communication platform for short-term rental operators. It connects to 45+ property management systems — including Guesty, Hostaway, Lodgify, Cloudbeds, OwnerRez, and Beds24 — and automates guest messaging across WhatsApp, email, and OTA platforms like Airbnb and Booking.com from a single unified inbox.

Cendra's AI agents handle guest inquiries, check-in instructions, upsells, and issue resolution autonomously, while giving property managers full visibility and control through a human-in-the-loop copilot interface.

## Who Uses Cendra

Cendra is built for short-term rental operators who manage properties on platforms like Airbnb, Booking.com, and Vrbo through a property management system. Whether you manage 5 properties or 500, Cendra automates the repetitive guest communication that consumes your team's time.

**Property managers** use Cendra to:

* Automate 80%+ of guest messages without sacrificing quality
* Respond to guests in seconds, 24/7, across WhatsApp, email, and booking platforms
* Sync all guest and reservation data from their PMS automatically
* Generate additional revenue through automated upsells
* Monitor AI performance and intervene when needed through the copilot

## How Cendra Works

Cendra connects to your existing property management system and communication channels, then deploys AI agents trained on your property data:

1. **Connect your PMS** — Cendra syncs properties, reservations, pricing, and guest details from your PMS in real time
2. **Connect your channels** — Link WhatsApp Business, Gmail, or Outlook to receive all guest messages in one inbox
3. **Train your AI** — Cendra builds a knowledge base from your property data. Add house rules, local tips, and custom procedures
4. **Test in Sandbox** — Send test messages to your AI agent before going live. Verify it handles common scenarios correctly
5. **Go live** — Deploy your AI agent to handle guest messages automatically, with full control over what gets automated vs. escalated
