0%
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

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.

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 designCISO & 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.
