On this page
Hosts ask us one question more than any other: "Do I need a PMS, or just something that answers guests?" The honest answer is that these are different jobs, and many hosts buy the wrong one first. This page lays out the three categories, what each actually does, and a simple rule for choosing.
The three categories in one table
| PMS | AI co-host (PMS add-on) | AI front desk | |
|---|---|---|---|
| Main job | Operations: calendars, channel sync, pricing, cleaning, reports | Messaging help inside a PMS | Guest conversations, 24/7 |
| Needs a PMS? | It is the PMS | Yes | Usually no |
| Answers guests on its own? | Templates and scheduled messages only | Some draft, some send | Yeswith the host deciding what it may send |
| Who it suits | Hosts with calendar sync problems or many channels | Hosts already on a PMS who want fewer messages | Hosts whose main pain is the inbox |
| Typical 2026 price shape | $9 to $70 per listing, often with contracts | Included or $7 to $20 per listing on top | $12 to $30 per listing |
What a PMS is for
A property management system is the back office. It keeps one calendar for all your channels so you do not get a double booking, pushes prices to Airbnb and Booking.com, schedules cleaners, and produces reports. Hospitable, Hostaway, Guesty, Lodgify, Uplisting, Smoobu and Hostfully are the names you will meet.
A PMS also has an inbox and templates. "Welcome, here is the door code" at 3 PM on arrival day. "Checkout is at 11, please leave the keys on the table" the night before. These scheduled messages are useful, and for years they were what "automation" meant.
What a PMS does not do, by default, is read a guest's reply and answer it. When Mei writes "we land at 6 AM, can we drop bags?", the template has already fired and the question sits in the inbox until you wake up.
When you need a PMS: you list on three or more channels, you have had a double booking, you have staff who need a shared calendar, or you are above roughly 20 listings and the spreadsheet has broken. In Thailand, Agoda is a big channel and some PMS tools connect to it natively (Hospitable and Hostex do, as of October 2026).
When you do not: one or two listings on Airbnb only, with a cleaner you message on LINE. A PMS at this size is paying for plumbing you do not have.
What an AI co-host is
"AI co-host" is a marketing term more than a category. Most often it means an AI messaging feature inside a PMS, or a messaging-only product that plugs into one. Lodgify markets an "AI co-host". Hostaway has AI Replies, Hospitable has AI on its Mogul plan, Guesty has ReplyAI. HostBuddy AI and Besty AI are separate products that sit on top of these systems.
The useful question is not the name but two behaviours:
- Does it send, or only draft? Hospitable's autonomous replies are on its $99 Mogul plan only, with a second-model check. Hostaway's default is draft for approval with opt-in auto-reply per topic. Lodgify drafts only. HostBuddy sends from its Elite tier upward. As of October 2026; check each pricing page for the current figure.
- What does it answer from? Most read your listing and a knowledge base you fill in. Some can only see what is in the PMS.
When an AI co-host fits: you already pay for a PMS, you are happy with it, and you want the inbox quieter without changing anything else. The add-on is usually cheap, from about $7 per listing on top.
The trade-off: you now depend on two vendors for one conversation, and the AI can only be as good as the knowledge you keep in the PMS.
What an AI front desk is
An AI front desk connects to Airbnb, Booking.com and Vrbo directly and treats the guest conversation as the main product, not a feature. The full definition is at /resources/what-is-an-ai-front-desk-for-short-term-rentals. The short version: it answers routine questions on its own, drafts replies for the rest, and escalates anything unusual to the host.
When it fits: your biggest cost is time in the inbox, especially at night and in languages you do not speak. You have 1 to 50 listings and no particular wish to run a PMS. You want the host to stay in charge of policy.
What it does not give you: calendar sync, a booking engine, payments, locks. If you need those, you need a PMS too, or a bundle that includes them (Nowistay, for example, includes a channel manager, WhatsApp inbox and smart locks in one plan; Boom Host bundles messaging with cleaning and pricing).
A rule for choosing
Write down your three biggest time sinks for one week. Hosts tend to find one of these patterns.
Pattern A: the inbox. "Where is the key card", "early check-in?", "the wifi?", at midnight, in Chinese. Get an AI front desk first. Add a PMS later if channels multiply.
Pattern B: the calendar. Double bookings, prices out of sync, cleaners unsure which unit. Get a PMS first. Switch on its AI replies if it has them, or add a messaging tool later.
Pattern C: both, at 20+ listings. You will likely end up with a PMS for operations and either its built-in AI or a separate front desk for conversations. Compare the total per listing; add-ons stack up.
Costs as of October 2026, rough and per listing per month: a PMS runs from about $9 (Guesty Lite plus 1% of revenue) to $58 (Lodgify, one listing) to reported $80 to $175 total (Hostaway, 1 to 4 listings, with a contract). Messaging add-ons run $7 to $19. Standalone AI front desks run about $15 (Nowistay) to $29 (Tokay). Check each pricing page for the current figure.
Where Tokay sits
Tokay is in the AI front desk column. It connects to Airbnb, Booking.com and Vrbo in about ten minutes with nothing to install and no PMS required. Pam answers guests in more than ten languages; the other five agents cover pricing suggestions, expense slips, cleaning briefs, review replies and a morning summary, with the host approving the decisions. It does not include a channel manager, locks or payments, so if you are in Pattern B you will still want a PMS. One plan, $29 per listing per month, $24 billed yearly, lower from 10 listings. Prices at /#pricing.
Questions hosts ask
Can I run an AI front desk and a PMS at the same time? Yes, and many hosts at 10 or more listings do. The PMS handles calendars and pricing, the front desk handles conversations. Make sure only one of them sends guest messages so a guest does not receive two replies.
Is Airbnb's free AI reply enough instead of all this? For one Airbnb-only listing with simple questions, it may be. It answers from listing facts only and does not work on Booking.com or Vrbo. If you want replies in the guest's language from your own knowledge base, with escalation to you, you need more.
I am in Thailand and most of my bookings come from Agoda. Which category covers that? A PMS with native Agoda connectivity (Hospitable and Hostex as of October 2026) will sync that calendar. For messaging, check whether the AI tool reads Agoda conversations; Tokay answers Airbnb, Booking.com and Vrbo guests and does not connect to Agoda.
