Digital & Platforms
Cerfi. The digital employee of your Maison.
Installed on your own site. He welcomes, answers, speaks, books and receives your documents — under your governance, in your brand.
Not a chatbot: a governed operational concierge, who knows when to step aside for a person.
Cerfi already works on cerfland.fr — this site’s conversation is him.
The face of Maison CerfLand.
Cerfi’s identity belongs to CerfLand and is not offered for selection. At your house, he wears the portrait your Maison settles on from the library, further down this page.
What Cerfi is
Four layers.
One order of precedence.
A generic chatbot improvises from what it knows of the world. Cerfi answers from what your Maison has approved, reads your systems at the moment of the question, and stops where a person must take over. Your sector’s industry expertise is maintained by CerfLand and connected Maison by Maison.
From the foundation to your Maison — choose a layer.
General intelligence
Understanding language, context and a visitor’s intent, across several languages.
- Who answers for it
- The language model Cerfi runs on — written neither by you nor by us.
- What it contains
- Understanding a sentence, its language and its intent, and holding a conversation. French and English are publicly available today; any other language opens establishment by establishment.
- An example
- A guest writes at 23:40, in English, two questions in one sentence: Cerfi understands there are two, and answers in the guest’s language.
- Where it stops
- It understands; it is not an authority. On its own it states no price, no availability and no rule of your Maison.
CerfLand industry expertise
Your trade’s vocabulary, how it actually works, your sector’s dated professional frame, and the situations that call for a qualified human. Sourced and versioned.
- Who answers for it
- CerfLand: each skill is sourced, dated and versioned. You do not edit it; your information prevails over it.
- What it contains
- Eleven industry skills, one per sector, at the same library version. Each holds four things: the vocabulary, the situations, the professional frame and the limits.
- An example
- It never merges France and Monaco: two distinct frames, kept apart.
- Where it stops
- An industry skill describes the trade. It never speaks for your Maison: your services, your prices, your availability and your rules always prevail.
Your Maison’s knowledge
Your services, your wording, your boundaries — what you approved, and nothing else.
- Who answers for it
- Your Maison — this knowledge is yours, and every approval is recorded with its author.
- What it contains
- Everything enters as a draft. Nothing is used before it is approved, and autonomous use is a second, separate decision. An approved version is never overwritten: it is replaced.
- An example
- “Is the spa open on Sunday?” — the answer comes from the hours you approved, not from a guess.
- Where it stops
- If it is not there, Cerfi says so — and offers to pass the question to a person. He does not invent.
Your connected systems
Your availability and your appointments, read from your connected calendar — the real state, at the moment of the conversation.
- Who answers for it
- You: they are your own tools, read live, at the moment of the conversation.
- What it contains
- Your Google Calendar, once connected · email confirmations, under your brand · secure document intake, where it is configured · your console, where everything he passes on arrives.
- An example
- “Do you have a slot on Thursday?” — he reads the calendar at the moment of the question, and an appointment is confirmed only once it is really written into it.
- Where it stops
- He reads only what is really connected, and takes no payment.
If the industry skill and your own information differ, your information and your systems always prevail.
Cerfi handles
- The welcome, on your site, in the visitor’s language.
- Answers, from your approved knowledge.
- Appointments, in your real calendar once it is connected.
- Secure document intake, where it is configured.
- Handing over to a person — announced, never in silence.
Always returns to a person
- ComplaintsAlways handed to a person.
- Discounts & refundsNever decided by Cerfi.
- Legal mattersAlways left to the Maison.
- Outbound publishingUnder your explicit approval.
Guard-rails no setting can change, whatever the autonomy mode.
What he actually does
Four duties.
One livery.
One employee, four duties, and the same Maison livery in every one of them — at your place, on your own site, not on ours.
01
Front of house
He welcomes every visitor in your Maison’s tone, in their language, and answers only from knowledge you have approved.
Real capture — Maison Aurelia, our outside test bench: a site that is not cerfland.fr, where Cerfi sits exactly as at a customer’s.

Front of house — He welcomes every visitor in your Maison’s tone, in their language, and answers only from knowledge you have approved.
What he knows
One Cerfi.
Eleven industry skills.
General intelligence is not enough.
A general model can hold a conversation. A trade has its own vocabulary, its own frame and its own limits.
Today, Cerfi answers with general intelligence, your Maison’s approved knowledge and its connected systems. The industry expertise shown here is the library CerfLand maintains; connecting it to the conversation is done Maison by Maison.
Cerfi’s four layersThe available skills
Eleven sectors, one skill each, at the same library version.

He works on a phone.
The same conversation, the same governance, one thumb.
The Maison’s side
A cockpit, delivered with him.
These are not screenshots: they are the real screens of the customer space, mounted here on a fictional client. The customer space is French today; the product is not.
Real components, mounted live
What needs your decision, first.
The very component of the customer space, on a fictional client.
A prepared reply waits for your go-ahead.
The real validation centre, on invented requests.
One autonomy setting. Permanent guard-rails.
The real matrix, capability by capability.
Nothing is used before your decision.
The real knowledge studio, with fictional sources.
The face, the name and the tone you give him.
The real screen where the Maison picks the portrait and publishes its identity.
Governance
Governance is the product.
One autonomy setting — automatic, semi-automatic or manual — and guard-rails that cannot be set at all: whatever commits the Maison always returns to a person.
Complaints
Always handed to a person.
Discounts & refunds
Never decided by Cerfi.
Legal matters
Always left to the Maison.
Outbound publishing
Under your explicit approval.
The autonomy level, capability by capability, in the customer space.
The permanent guard-rail, as the product writes it.
Installation
One line of script.
Your site.
Cerfi installs at your place, not ours: one line in your page, one public key per site, and the conversation opens under your brand. The Maison keeps control of every allowed domain.
<script src="https://www.cerfland.fr/cerfi/widget.js" data-cerfi-site="wc_YOUR-KEY" async></script>The real line, exactly as it is served. Only the public key changes from one installation to the next.

The incarnation
One Cerfi.
The face you give him.
A palace’s welcome desk, a gallery’s front of house or a yacht club’s concierge: the same intelligence, governed the same way, under a different face. Open a card from the library: the portrait you select becomes the face of your welcome.
Forty-two portraits in the library, or your own if you have one. By default your Maison settles on a single face, the same on every installation you hold; as an option, the launcher may let a few presences succeed one another before the conversation. The moment a visitor opens it, the face settles.
Cerfi at the welcome deskHover a card to look at it; click to select it. The arrow keys work too.
This face, your name, your title, your tone.
The Maison picks a portrait from the approved library — seven here, forty-two in the product — or uploads its own, on the “Marque & expérience” (Brand & experience) screen shown above; his name, his title and his way of speaking are set in the same dashboard.

The engagements
Included in each of the five plans.
From the ÉMERGENCE programme to the PILOTE relationship, Cerfi is present at every level — with a scope, voice minutes and a level of steering that grow with the relationship. The prices are public, on a single page.
