✦ In brief

In a public service one-stop shop, a Blue Lemon Agent agent assists the adviser with the recurring requests — answers on family benefits, health insurance, pensions, tax, employment services or vehicle registration procedures, step-by-step help with online services, pre-filling of the everyday forms. It runs on local inference or is hosted in France on a resource dedicated to and isolated for each centre: the public's data is never exposed to a foreign service, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. The adviser stays the trusted contact; the time won back goes to supporting people who struggle with digital services. Live within a few weeks. Your public-sector staff write to it from Microsoft Teams, Slack or their email, and your users reach it on WhatsApp Business, the website chat or email — with no account to create and nothing to install. Reaching the administration from the tool people already have means less non-take-up of rights and equal access to the service. These connections are included in every plan, at no extra cost, within the number of connections your level includes.

Reference points describing our offer, not results measured at a client. The scale of the gain is confirmed by a pilot on your own scope.

The context

Why AI matters to one-stop shops — and why they hesitate

An adviser covers the procedures of dozens of public bodies — family benefits, health insurance, pensions, tax, employment services, vehicle registration — without being able to be an expert in each, facing people who often struggle with digital services and highly sensitive personal data.

! The issue

The adviser is caught between people who expect concrete help on very varied procedures and the impossibility of mastering every public body's rules in detail. Yet most consumer AI tools would amount to entrusting identities, income, family situations and people's files to a third party, often hosted outside Europe and subject to the Cloud Act.

Our answer

For supporting the public, AI is only of interest if it is sovereign and confidential by design. Local inference or an isolated resource hosted in France, systematic human oversight, every step approved by the person and the adviser: the time saved looking up information is never paid for in lost confidentiality. The aim is not to replace the adviser, but to give them back time for human support.

The decisive point

Protecting the public's data: sovereignty & compliance

A one-stop shop sees its users' most personal files. Here is how the architecture of our agents protects them, centre by centre.

Local inference

The agent can run on a machine at the centre: no data leaves the network, nothing passes through a cloud.

Hosting in France

Otherwise, a dedicated and isolated resource, hosted in France under French law — the public's data: processing and access within the European Union targeted by the architecture.

Reduced extraterritorial exposure

The public's data: architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.

One isolated resource per organisation

No pooling of data: an environment strictly dedicated to your centre, guaranteeing the continuity of the public service.

Encryption & controlled access

Encryption in transit and at rest, role-based access (RBAC), strong authentication and logging.

AI Act: governed deployment

The agent is strictly in support; no procedure is submitted automatically; traceability and human oversight from end to end.

What depends on the architecture chosen These points are not general guarantees: they are settled deployment by deployment, in the quotation.

  • The applicable location is that of the architecture set out in the quotation and verified before commissioning.
  • Local execution is announced only for the configuration explicitly described and accepted in the quotation.
  • The applicable isolation depends on the deployment mode set out in the quotation; no dedicated isolation is presumed.
  • The encryption mechanisms in transit and at rest, their components and key management are those documented for the architecture chosen.
  • Roles and permissions are configured and accepted for the identities and systems actually connected.
  • The events logged, their content, their retention period and who may access them are defined for the deployment chosen.
For the most sensitive data, SecNumCloud and HDS options are available — particularly relevant as soon as social or health data is processed. A single architecture is designed to answer both the GDPR and extraterritorial exposure. Designed for deployment in line with the GDPR and the AI Act, after the processing, roles and context-specific risks have been assessed.
Demonstration

See the agent at work

5 real situations, taken from those that come up most often. Pick one: the exchange unfolds as it would in your organisation.

A scripted demonstration. These exchanges show how the agent behaves — its sources, its refusals, what it leaves to your teams. Nothing is sent from this page, no model is queried here, and the matters named are fictional. That is precisely what we promise your data.
The behaviours shown here — monitoring, automation rules, routing and reminders — are configured with you during deployment, from your tools, your rules and your thresholds.
The architecture points named in these exchanges — location, local execution, isolation, encryption, role-based access, logging — are not a guarantee attached to the demonstration: they are those of the architecture set out in your quotation, and verified before commissioning.

The public body in this demonstration

Fictional public body

Vaunoy-sur-Sèvre France Services centre — run by the Val de Sèvre community of municipalities (fictional public body)

Service
Inter-municipal France Services centre — helping users with procedures of the partner agencies: family benefits, health insurance, pensions, tax, employment service, vehicle registration
Headcount
4 staff: 2 full-time France Services advisers, 1 half-time adviser, 1 front-desk officer — 3.5 full-time equivalents
Public served
11,400 inhabitants across 14 rural municipalities; one user in three says they are not comfortable with online procedures
Volume
470 visits a month, 62 % of them without an appointment; six agencies account for 84 % of requests; 7 use cases ready to deploy
Tools in place
France Services tracking portal, shared diary, service mailbox and six years of in-house guidance sheets — the agent plugs into them, nothing is replaced
Who decides
The centre manager sets how the service is organised; the lead adviser approves every summary handed to a user; the community council votes the resources
Room for improvement
43 minutes on average to handle a common vehicle registration procedure; 19 days' wait for a support appointment; 118 cases left incomplete last year for want of a single document

The Vaunoy-sur-Sèvre France Services centre wants to give back to face-to-face support the time that hunting for a procedure takes, and to see just as many users while sending them away with their procedure filed. The agent is hosted in France on an isolated resource dedicated to the centre and plugs into the tracking portal, the shared diary and the guidance sheets: it prepares the complete case, the lead adviser approves, the user signs their procedure and leaves knowing how to do it again. The exchanges below span one quarter, from the first enquiry to the review.

This public body, its figures and the exchanges that follow were invented for the demonstration. They illustrate a common situation; they describe no real service.

One-stop-shop assistant · hosted in France
I have read your 1,410 visits from the quarter and your six years of guidance sheets. I draw a gap your activity report did not show: 38 % of your visits concern just nine procedures, and they are the ones that take you longest to prepare.
The nine, in order: change of address on a vehicle registration document, housing benefit claim, declaring a change of family circumstances to the family benefits agency, health insurance entitlement certificate, pension record statement, income tax return, monthly employment service update, permit renewal, transport cover for medical care.
Why that gap sets the gain: these nine procedures are not difficult, they are scattered. Your advisers are not looking for a complicated answer, they are looking for the right page at the right agency, several times a day. Your own records show 12 minutes on average for an enquiry of this kind.
What I have already written, and it is waiting for you this morning: the nine sheets are done — the competent agency named, the documents required, the stated processing times, the date on which I checked the rule — and the matching form comes pre-filled with what the user gives at the desk. An enquiry goes from 12 minutes to 3: across 210 enquiries a month, 31 hours returned to the service.
The strength of a dated sheet, and it is an argument to use with your funder: every answer carries the agency with authority and the date it was checked. A dated answer can be verified, challenged and corrected in one morning, for all three advisers at once — that is what protects a centre, and no answer given from memory allows it.
What I propose: the lead adviser reviews the nine sheets, I apply them at the front desk from tomorrow, and I bring you the next nine on Friday — they cover a further 21 % of visits, 59 % of the total. Each sheet is corrected in one word: this is your own material, dated and set straight. quarterly-overview_1410-visits.pdf9 procedures account for 38 % of visits
⛓ Sourced · 1,410 visits over the quarter, the centre's guidance sheets, agencies' official pages
A user comes in: she has just moved, she needs to update her vehicle registration document and she has no account on the registration agency's site. What do we do?
The path is ready, the form is pre-filled on screen and her three documents are checked. She leaves with her application filed today, not with a list of things to do.
What I have already done while she waited:
· I opened the exact online procedure at the right agencyan online procedure is one carried out entirely online, with no paper form and nothing to post. Finding it takes twelve minutes when you go looking; it is on screen.
· I checked her three documents: current registration document, proof of address, identity document. Her proof of address is four months old: it is valid. Without that check she would have gone home for a utility bill — and those return trips are what makes up your 118 incomplete cases from last year.
· I pre-filled the form with what she presented at the desk, every field carrying the document it comes from.
· I spared her creating an account: she already holds a national digital identitythe scheme that lets you use credentials you already hold with one government service, tax for instance, to sign in elsewhere without a new password. One user in two has one without knowing it, and I check before having anyone create an account.
The one act that stays hers, and it is a strength: she signs in to her own account and validates. Access to a personal account belongs to its holder, and it is that click which makes the application hers — enforceable against the administration, and open to challenge by her if the answer is slow. Everything before that click is already done.
The time this shifts: handling a procedure of this kind drops from 60 % to 10 % of the time it took — 43 minutes become 7. Those 43 minutes are preparation and search time, not time spent with her: that does not fall, it is precisely where we put it back.
What I propose: I print the summary with the tracking number as soon as it is filed, and I book her a follow-up appointment in three weeksthe same act brought your incomplete cases down from 29 to 9 a quarter. The adviser decides whether to offer it; it takes one click. user-path_change-of-address.pdfForm pre-filled, 3 documents checked, one page to hand over
⛓ Sourced · the agency's official online procedure, documents presented at the desk, form pre-filled on screen
A lot of people leave without knowing they were entitled to something else. We do not have time to ask everyone everything.
Over the quarter, 41 situations where a possible entitlement was not being claimed — and for each of them the claim is already written and pre-filled, ready to be signed the day the adviser asks the question.
Non-take-up means not claiming an entitlement you might be eligible for: because you did not know, because the procedure discouraged you, or because nobody asked the right question. It is the first blind spot of a fast front desk, and the heaviest figure in your activity report.
How I spot them, and it is mechanical: the details a user already gives for the procedure in hand — household composition, employment situation, age, tenant status — are exactly the ones that open other entitlements. Nobody has to ask again, they are already on the table.
The three most frequent families at your centre:
· 17 situations where housing benefit looked possible and was not being claimed, spotted during an entirely different procedure.
· 13 situations where the user came about their pension record without having claimed supplementary health cover.
· 11 situations where a change of family circumstances had been declared to no agency at all — and an undeclared change always ends in an overpayment to be repaid.
Who opens the entitlement, and why it is your best argument: the decision belongs to the agency, and I hand it over fully prepared. I write the question the adviser puts to the user, I attach the pre-filled claim and the list of documents, and the agency decides — by a reasoned, dated decision the user can challenge if they disagree. That challengeability is what makes an entitlement hold; an entitlement opened without a reasoned decision would not survive three weeks of appeal.
The figure that does not flatter me: of the 41 flags, 29 led to a question asked by the adviser and only 12 to a procedure actually started. 12 out of 41. The cause is measured and it is not the spotting: a bare flag cost twelve extra minutes per visit, and those twelve minutes are not there every day.
What I did with it, and I replayed it over your quarter: the flag no longer travels alone, it travels with the claim already filled in and the documents gathered — the adviser's part falls from 12 minutes to 2. On the family of undeclared changes of circumstances, procedures started rise from 4 out of 11 to 11 out of 11, without a minute more per visit.
What I propose: start with that family, because that is where the user quietly loses money, and extend to the other two whenever the manager says so. The 41 claims are written: they are waiting for a signature, not for development work. non-take-up_41-situations-flagged.pdf41 claims pre-filled, 12 adviser minutes down to 2

The public's data never leaves the centreLocal inference or an isolated resource hosted in France; no data entrusted to a foreign third party.
Data in France, under French lawThe public's data: minimisation and location in France, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.

Human oversight & traceabilityAnswers across public bodies: every change to the service is logged, in line with the requirements of the AI Act.
Frequently asked questions

Your questions, our answers

Does the agent carry out the procedures in the person's place?
No: it guides and prepares; the person and the adviser approve every step. No administrative decision is automated.
Does the public's data leave the centre?
No: local inference or hosting in France, an isolated resource, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.
Does the agent fill in the forms for the person?
It pre-fills and explains, but the person approves and signs their own procedures; the adviser keeps the human support.
Does it work for people who do not speak French?
It answers in French and prepares the summary of documents and steps; the adviser stays the trusted contact for the support itself. Plain-language rewriting, easy-read transcripts and translation belong to a separate agent, Accessibility and inclusion, ordered on its own.
Does the agent state that it is an artificial intelligence?
Yes, from the very first interaction, and this is not a configuration option: since 2 August 2026, Article 50(1) of the European AI Regulation requires that any person interacting with an AI system be informed, unless this is obvious. The announcement is built into the greeting, in the other party’s language, and they can ask for a human at any time.
How long does it take to deploy an agent?
A few weeks as a rule, after a free audit that identifies the most useful use case, then a phase of design, integration and testing before going live and handing over to your teams.
Do we need a technical team in-house?
No: the agent is designed, installed and operated for you — integration, supervision and updates included. Your teams concentrate on their work, with guided familiarisation.
Do we have to change software?
No. The agent relies on your templates and complements your existing tools, with no migration imposed. We adapt the integration to your environment.
Which tools can users use to reach the agent?
The ones they already have. The agent answers on WhatsApp Business, the website chat and email: users have no account to create and no application to install. This is a lever for access to the service — WhatsApp and the telephone reach people an online form never does, which reduces the non-take-up of rights and serves equal access. Internally, your public-sector staff talk to the agent from Microsoft Teams, Slack or their email, without switching tools. Oversight runs from a web dashboard. These connectors rely on open standards, including the MCP protocol; they are included in every plan, at no extra cost, within the number of connections your level includes. Only the fees charged by the platforms themselves — WhatsApp Business bills per conversation, and the gateway bills the text messages sent — are passed on at actual cost, with no margin, outside the subscription.
Can the agent notify users by text message?
Yes, as an option — and it is the channel that reaches the people the others never do. A text message arrives on an ordinary phone: no email address, no account, no app, no data plan and no smartphone. Reminding people by text message of a support appointment or of a document still missing means fewer entitlements going unclaimed and more equal access to the service. It is an outbound notification channel, not a conversation channel: users do not write to the agent there — they reach you on WhatsApp Business, the website chat or email. The message announces without detailing — never the reason, never the detail of the situation — and never contains a payment link, a login or a password: users reach the service the way they usually do. Delivery goes through a gateway established in the European Union; the messages sent are passed on at actual cost, with no margin, and the channel itself is an optional module, set out on the pricing page.
