of inbound traffic are level 1 requests.

The structural overload of the front desk

Nearly 60% of inbound traffic concerns routine first-level requests: opening hours, supporting documents for civil registry, departmental routing or case follow-up. At peak times, this volume saturates the switchboards, makes users wait and puts constant strain on front-desk staff.

Public service does not lack commitment. It lacks minutes.

ARIA absorbs the repetitive load to give time back to the complex cases that require human expertise.

ARIA answers, understands and routes

It serves the user 24/7, by phone or through your digital portals, without ever improvising.

L1

The national bedrock

Interconnection with public State data, regularly updated, to align answers with the national regulatory framework and official administrative procedures.

L2

The local context

Automated indexing of your institutional website to align answers with your hours, your local specifics and your existing user portals.

L3

Fine-grained control

Precision tuning from your secure dashboard to integrate your exclusive local directives and internal guidance notes, without complex document imports.

Every answer cites its source. Live.

Mode Clarté shows, for every exchange, the answer given to the user, the exact regulatory source and the time-stamped audit log.

Absolute explainability

Every answer traces back to its exact documentary source, time-stamped. Any semantic doubt is immediately escalated to your teams.

Keeping the human link

At the slightest ambiguity, ARIA transfers the call to the switchboard and sends the text summary of the exchange to the agent's desk.

Simulation of a real exchange. Every answer cites its source, time-stamped.

How it works

The journey of a call

01

The user contacts you

By phone, web widget or QR code — the same number, the same site as today. Nothing changes for them.

02

ARIA answers in under 2 seconds

It identifies itself in your name, understands the request in natural language and keeps the context of the exchange.

03

It answers, routes or acts

Sourced answer via Mode Clarté, routing to the right department, or handling the procedure itself.

04

It logs, and escalates if needed

Every exchange is logged and time-stamped. At the slightest doubt, transfer to an agent with the conversation summary.

Channels & integration

Reachable everywhere, by everyone

ARIA answers your users at any hour and in their language — by phone, on your website or via a simple QR code. The three channels converge into a single agent.

Phone

Behind your current number (SIP link). Nothing changes for the user, no telephony overhaul.

Web widget

On your website, in your colours. Discreet integration, consistent with your visual identity.

QR code

On your posters, counters and letters. One scan, and the user talks to ARIA.

One agent, one queue, whatever the channel.

Brussels · Belgium

Reference market: the 19 Brussels-Capital communes, Wallonia, Flanders and the EU institutions.

Paris · France

Company seat and operations coordination.

Barcelona · Spain

Deployment to local authorities and cultural venues, with multilingual reception FR / ES / CAT.

Points of view

What it changes, for everyone

The Directeur général

“I guarantee service continuity with limited resources — and I can audit everything.”

Switchboard relief, controlled costs, GDPR/WCAG/AI Act compliance and traceability of every answer.

The front-desk agent

“I'm no longer buried in repetitive calls. I focus on the cases that need a human.”

ARIA absorbs level 1 and sends the exchange summary to the desk when it escalates.

The user

“I get a clear, sourced answer, at any hour and in my language.”

Available 24/7, by phone, widget or QR — ARIA answers in the user's language.

The doctrine

Why ARIA

Transparent by designMode Clarté

Traceability is not an option, it is the backbone of the code. Mode Clarté provides in real time the user answer, the cited regulatory source and the full audit log: confidence score, latency, model.

Contractual sovereigntyguaranteed by DPA

Data is processed on infrastructure located within the European Union, guaranteed by contract (DPA), with no reuse of your data for model training. Audio files are not retained after the call.

European by design

CISO & DPO compliancenative

GDPR, WCAG 2.1 AA accessibility and the AI Act are built in from the very first line of architecture. Impact assessments (DPIA) and the Article 30 record are delivered turnkey.

ARIA Insight

It doesn't just answer. It reveals.

From exchanges — aggregated and anonymised — ARIA surfaces what's going wrong in local public service.

Friction score

Public information that's vague, missing or contradictory and makes people ask the same questions.

Non-take-up signal

Requests for benefits or rights made without clear knowledge of existing schemes.

Load anticipation

Upcoming trends and peaks, to size the front desk before it saturates.

Aggregated, anonymised signals — never personal data.

Before the demo, our charter of commitments

ARIA is not a communications tool.

It is not built to generate announcements or impress a leadership committee, but to relieve a real telephone switchboard.

ARIA knows when to stay silent.

If the national or local documentary resource is missing, incomplete or contradictory, ARIA declines to answer and hands over. We put administrative rigour ahead of technological performance.

We do not compromise on security.

The cost of our infrastructure reflects the strict isolation of your data. Our pricing is transparent and calibrated to comply with public procurement rules.

Frequently asked questions

What a Directeur général, a CISO or a DPO wants to know

Where is the data hosted?
Processing takes place on infrastructure located within the European Union, guaranteed by contract (DPA). No data is reused to train models, and audio files are not retained after the call.
Does the user know they are talking to an AI?
Yes. ARIA states it at the start of the exchange, in line with the European AI Act (transparency, Art. 50). Transfer to a human agent remains possible at any time.
What happens when ARIA does not know?
It does not guess. If the documentary resource is missing, incomplete or contradictory, it declines to answer and transfers to an agent with the exchange summary.
How does ARIA integrate with our existing switchboard?
It answers behind your current number (SIP link), or via a web widget and a QR code. No change for the user, no overhaul of your telephony.
Are you GDPR, accessibility and public-procurement compliant?
GDPR: Article 30 record, DPIA and DPA provided. WCAG 2.1 AA targeted (EN 301549 / Belgian Web Accessibility Act). Pricing is calibrated to comply with public procurement rules.
How long does deployment take?
Target deployment in 14 days, with no interruption to the existing service: configuration, real-world testing, then go-live.
