Key takeaways
- The hotel operating system is the workplace, the shared core is the definition layer underneath it, and the PMS assistant is a worker inside the workplace.
- All three carry the status word Built; none is Live, and the shared core runs in a public demo environment on a fictional hotel.
- The hotel operating system holds 400+ database tables, 150+ built-in reports and 5 languages (June 2026).
- An AI assistant can find, hold and book a room on the demo property within limits the hotel sets.
- We have no trained model yet: what exists is the architecture, the decision infrastructure a model would run inside, and a benchmark to choose the model.
AI Otel PMS is the hotel operating system a hotel would run on: reservations, front desk, housekeeping, billing, reports and compliance in one place, built and ahead of launch. AI Otel Core is the shared core that defines each hotel action once for people, partners and AI assistants. The PMS assistant serves the hotel's own team.
A hotelier reads three product names on the same site in ten minutes and asks the fair question: are these three products, or one product described three ways? It is a fair question because the answer decides what you would actually buy, connect or ask for. After reading this page you will be able to sort the three names in one step, by asking who the user is. If you have met terms like the shared core or the decision record before, the AI Otel glossary covers them in more depth.
Why does AI Otel use three names for what sounds like one product?
Because the three do different jobs, and each one can be described honestly only with its own status word.
The hotel operating system is where the work happens. A reservation is taken, a room is assigned, a charge reaches the guest's bill, and the business day is closed. The shared core is where each of those actions is defined once, so a staff screen, a partner system and an AI assistant all call the same definition instead of rebuilding it. The PMS assistant is a worker inside the operating system: it answers questions about the hotel's own property and performs routine actions on that hotel's data.
The split has a practical benefit. A hotel can run the operating system without opening anything to partners, and a partner can connect to the core without ever seeing the front desk. Each name also carries a status word, and mixing the names would let a demo feature borrow the credibility of a built product. Keeping them apart keeps the claims checkable.
There is a one-question test that sorts them: who is the user? A receptionist uses the hotel operating system, a partner's software uses the shared core, and the hotel's own team asks the PMS assistant.
Key pointThe three names in three lines
AI Otel PMS: the system a hotel runs its day on. AI Otel Core: the shared core that defines each action once for people, partners and AI assistants. PMS assistant: the helper that answers the hotel team's questions and carries out routine actions.
What is AI Otel PMS, the hotel operating system?
It is the system a hotel would run its day on: reservations, front desk, housekeeping, billing, restaurant sales, reports and compliance in one place. It is built and working, ahead of launch.
The modules share one record. A charge posted at the restaurant appears on the guest's bill without a second entry, and housekeeping sees the room status the front desk changed. Reservations, groups and room assignment sit in one system, protected against selling the same room twice. Single hotels and groups run from one login, and travel agents and corporate clients book through their own portals.
Financial records are never deleted: corrections are voided and reversed, and the night audit closes the business day. That is what makes a report trustworthy a month later. Compliance is built into the core rather than bolted on: KBS guest identity notifications are prepared and sent from the check-in flow, KVKK consent, data export and retention periods sit in the data model, and e-Fatura and e-Arşiv are part of the same system, with e-invoices waiting for a person's review before sending. On regulation, confirm dates, penalties and your own case with an accountant or legal adviser.
Scale, stated plainly: 400+ database tables, 150+ built-in reports and 5 languages, Turkish, English, Arabic, Russian and German (June 2026). Status, stated plainly: built and working, ahead of launch. OtelCiro, the ecosystem's hotel growth and consultancy arm, works with paying hotel clients today; the operating system is software, and software and consultancy are different things.

What is AI Otel Core, the shared core?
It is the layer where every hotel action is defined once and served to three kinds of caller: the hotel team, partner systems, and the AI assistants people already use.
The problem it solves is drift. Without one definition, the same booking rule gets rebuilt in the front desk screen, in the hotel's own website and in every partner integration, and the three slowly disagree. With one definition, each caller gets its own door, and the rule behind every door is the same. A change to the rule reaches all three at once.
AI Otel Core builds every hotel action once. The hotel team, partners and the AI assistants people already use each get their own door. It is built and runs in a public demo environment on a fictional hotel; nothing in it is Live, and the demo property is not a customer. An AI assistant can find, hold and book a room on the demo property within limits the hotel sets. A hold is a temporary claim on a room: when it expires, the room returns to inventory.
Partners connect through a versioned, OAuth-secured booking API and receive signed booking events. A signed event is a message the receiver can check really came from us; versioned means old integrations keep working when the API changes. The core is not a screen a receptionist works in, and it is not a model. It is the definition layer the operating system, partners and assistants all read from. The mechanics are described in how hotel teams, partners and AI share one system.
What is the PMS assistant, and how does it differ from the shared core?
The PMS assistant works for the hotel's own team: it answers questions about that property in plain language and carries out routine actions, and a person confirms anything sensitive. The core defines actions; the assistant is one caller that uses those definitions on the staff's behalf.
It answers from the hotel's own data, so the answer to "how many rooms are still unsold on Friday" comes from that hotel's inventory, not from a general idea of what hotels are like. Every action it can take sits in one of three safety tiers: some run directly, some need one person's confirmation, and the most sensitive need two.
Two records keep the boundary visible, and they do different jobs. The decision record governs changes: small changes apply automatically and are logged, larger ones wait for a person, and every change can be undone, except a message already sent to a guest. The audit record governs history: past records can only be appended, changing or deleting them is closed in the database, and if someone still alters one, the chain shows it. The distinction is worth a page of its own: decision record and audit record.
The assistant is the seed of the Hotel Brain. The Hotel Brain is architected and entering training; today the assistant answers from each hotel's own data, and we have no trained model yet. What a team can ask, and what needs a person, is covered in the PMS assistant in detail.
Which one does what? The three names side by side
Read the second column first: the user tells you which name you need.
| Name | Who it serves | What it does | Status |
|---|---|---|---|
| AI Otel PMS, the hotel operating system | the hotel's staff | runs the day: reservations, front desk, housekeeping, billing, restaurant sales, reports, compliance | Built, ahead of launch |
| AI Otel Core, the shared core | hotel teams, partner systems, AI assistants | defines each action once and serves it through separate doors | Built, demo on a fictional hotel |
| PMS assistant | the hotel's own team | answers questions, carries out routine actions, a person confirms anything sensitive | Built |
If the user is a receptionist, a housekeeper or a night auditor, the name you need is the hotel operating system. If the user is a partner's software or an AI assistant, the name you need is the shared core. If the user is a manager asking a question in plain language, the name you need is the PMS assistant. Status words travel with the names, so copy them together: a name without its status word is a claim without a date on it.
Is any of this a trained AI model?
No. The operating system, the shared core and the PMS assistant are built software; the Hotel Brain and the Platform Brain are architected, the Industry Brain is on the roadmap, and we have no trained model yet.
The honest sentence, unchanged: "We have no trained model yet, and the product says so on screen. What exists is the architecture, the decision infrastructure a model would run inside, and a benchmark to choose the model." The benchmark is built and not yet run: 30 cases, 5 traps. Results will be published when measured, and no score exists today.
Status words in plain words: Built means working software ahead of launch, not in customers' hands. Live means operating today, and only OtelCiro is Live. Behind none of the three names is there a count of hotels, bookings or users, a connected agency or OTA, a certification or a testimonial. Hosting and AI processing in Türkiye are on the roadmap; until that work is done, we do not claim it.
Watch outFour phrases that are wrong about these products
"In production" should read "built, ahead of launch". "Used by hotels" should read "built and working, ahead of launch". "Trained on your hotel's data" should read "the assistant answers from your hotel's own data; no trained model yet". "Connected to the OTAs" should read "availability and rates flow to the major OTAs through our Channex integration, now in pre-production testing".
What to do next
Pick the door that matches who you are. If you run a hotel and want to see how the operating system would carry your day, talk to OtelCiro. If you are a partner, an institution or an investor and want the architecture explained, request a briefing at info@ai-otel.com or through the contact page.
The three names fit together in one order: the shared core defines the action, the hotel operating system is where a person performs it, and the PMS assistant is the helper that answers and acts inside it, with a person confirming anything sensitive.
Frequently asked questions
Is AI Otel PMS the same thing as OtelCiro?
No. OtelCiro is the ecosystem's hotel growth and consultancy arm and works with paying hotel clients today. The hotel operating system is AI Otel's built software, ahead of launch. The two are different kinds of thing, and the software should not be described as OtelCiro's product.
Can a partner connect without a hotel running the operating system?
Yes in design: partners and AI assistants connect to the shared core through a versioned, OAuth-secured booking API and receive signed booking events. Said plainly, the core is built and runs in a demo environment, and no partner is connected yet.
Does the PMS assistant need the Hotel Brain to work?
No. The assistant is built and answers from each hotel's own data today. The Hotel Brain is architected and entering training, and we have no trained model yet.
What does the word Built mean on an AI Otel product page?
Built means working software, ahead of launch, not in customers' hands. Live means operating today, and only OtelCiro is Live. Every product name should be read together with its status word.
Where can I see the shared core in action?
In a public demo environment on a fictional hotel, where an AI assistant can find, hold and book a room within limits the hotel sets. The demo host's availability changes, so we do not link it here; request a briefing instead.
