Ersona compared with Duve
PMS-neutral AI for hospitality. Ersona adds AI-powered sales, service and operations across the systems your hotel already uses.
Duve
A guest experience platform — “Personalized hospitality, at scale” — combining a branded guest app, online check-in with ID capture, digital keys, upsells and a communication hub, with DuveAI layered on the inbox.
Short answer
Duve digitises the guest journey and adds AI to the inbox. Ersona is the AI that runs the conversation and the work behind it, across the systems you already have. Both are legitimate — the question is whether you are buying a guest-facing platform or an operator.
Real and direct on messaging: both answer guest messages with reservation context on WhatsApp, email and OTA threads, both offer a draft-then-approve step, both sell extras with an optional approval, both put a guest-facing app in front of the stay, and both connect to Cloudbeds, Guesty, Hostaway, MiniHotel and Optima.
Choose Duve when…
You want the whole guest-facing journey from one vendor
Online check-in with ID capture and registration-card write-back, mobile keys across roughly twenty lock vendors, a white-label guest app, room directory, digital menus and mobile ordering — all under one contract.
Check-in and keys are the project
If the business case is contactless arrival rather than conversation handling, that is Duve’s home ground and they have built more of it than we have.
You want published pricing and enterprise references
Public plans with stated minimums, a published rollout time, and named references including Accor/MGallery, Sofitel and Brown Hotels.
You prefer AI kept away from money
Duve states DuveAI has no access to nightly rate, total price or payment status, and escalates billing questions to staff. If that boundary matches your risk appetite, it is a genuine feature, not a gap.
Choose Ersona when…
You want sales, service and operations on one layer
The same agent answers the enquiry, sells the extra, opens the task and chases it. A four-hotel group in Tel Aviv, 187 rooms, runs reservations, guest service and staff task management on Ersona.
You want the AI to transact, with your rule in front of it
Ersona sells rather than escalating the sale, and approval is the control: per product and per property, a purchase can complete immediately or wait for your team.
You want the phone included
Voice is one of Ersona’s channels, alongside WhatsApp, Instagram, Messenger, Telegram, email and website chat — each able to carry its own rules, automation and escalation on the same hotel context.
You don’t want to rebuild the guest journey to get the AI
Ersona runs on the channels and inboxes you already have, including the Guesty and Hostaway inboxes and the OTA threads relayed into them.
Different philosophies
The products are built around different questions.
- Centre of gravity
- DuveThe guest-facing digital journey — app, check-in, key, directory — with AI added on the inbox.
- ErsonaThe decision and the work behind the conversation, on whatever channel it arrives on.
- Where the AI sits
- DuveInside an owned guest-experience stack, and strongest where that stack is deployed.
- ErsonaOn top of the PMS, channels and inboxes the hotel already runs.
- Money in the conversation
- DuveUpsells run through the guest app; the AI is deliberately kept away from rates and payment status.
- ErsonaThe AI sells — the hotel’s own products and its partners’ services — with approval, not exclusion, as the control.
What they have in common
- AI answers with reservation context on WhatsApp, email, app chat and OTA threads
- Optional human approval before the AI acts on something sensitive
- Escalation to staff with the full thread attached
- A guest-facing app where guests can see and buy what the hotel offers
- Task management for the team
- Connections to Cloudbeds, Guesty, Hostaway, MiniHotel and Optima
Worth being precise about
- Duve publishes a large integration list that includes every PMS Ersona connects to. Coverage is not the argument on this page — operating model is.
- Duve states that DuveAI has no access to rate or payment data and escalates billing questions to staff. That is a deliberate boundary, and some hotels want exactly that.
- Duve’s published channels are WhatsApp, SMS, email, in-app chat and OTA messaging. If phone calls are part of what you need handled, ask both vendors directly.
Where Ersona is different
- 01
Commerce the hotel composes
The GuestApp storefront is built by the hotel: its own services and partner services such as the spa, sequenced by stage of the stay and filtered by room type, each set to buy-now or approval-required.
- 02
Per-channel behaviour on shared context
Phone, WhatsApp, Instagram, Messenger, Telegram, email and web chat share what the hotel knows, and each can be given different rules, automation, escalation and handoff.
- 03
Execution across your systems, with approvals
Where the connection supports it and you’ve authorised it, Ersona carries the outcome into the systems that need it instead of leaving a note for someone to re-enter.
What you keep either way
Your PMS. Your booking engine. Your data.
Nothing is migrated to work with Ersona: your PMS stays the system of record, your booking engine stays yours, and every conversation shows whether Ersona or a person owns it.

“It is working excellent — above my expectation. The AI understands context and handles guest requests naturally.”
Which fits your hotel?
Two honest answers.
Duve is likely the better fit for
A property or group buying a guest-experience platform — check-in, ID, keys, guest app and upsells — with AI messaging included.
Ersona is likely the better fit for
A team that already likes its PMS and its channels, and wants the conversation, the sale and the operational work handled together, phone included.
