Cluster capacity and cloud storage.
AI APIs & IT consulting
Practical integration of AI services, and advice on the rest.
Built & running
Web apps we designed, built and host
Live applications running on our own infrastructure.
AI helpdesk assistant
A meeting companion that listens, transcribes and advises.
It records a client conversation, transcribes it, and can be asked for advice at any point without stopping the recording — then writes a closing summary. Built on EU-hosted AI, behind an explicit consent gate, with encrypted logs.
- Live transcription
- EU-hosted AI
- Consent gate
AI assistant to your existing Document Management System
Ask a question in plain language, get the answer from your own documents.
Questions are typed or spoken, and follow-ups keep the thread. It searches a self-hosted index rather than the open web — one that can be built straight from an existing Document Management System — answers in the language it was asked in, and cites the sources behind every answer.
- Built on your DMS
- Voice or text
- Cited sources
Family tree builder
An invite-only tool for building a family tree together.
Relatives are invited by link and add their own branches. The tree renders as clean scalable graphics and exports to PDF. The conversational AI features allows for building the family tree simply by talking.
- Invite-only
- Multilingual
- Print & PDF export
Wedding apps
A set of three connected apps built for a multilingual wedding.
A live subtitle wall that listens to the room and projects the translation in real time — any spoken language in, any languages out; at this wedding it heard English, French and Bulgarian and captioned in Bulgarian and French. A menu builder that suggests dishes and recipes with AI, rolls every ingredient up into one shopping list and prints the finished menu in several languages. And a shared checklist the organisers edit together. All three install to a phone like a native app.
- Any language pair
- Installable PWA
- Realtime sync
Interactive AI avatar kiosk
An avatar that talks to you, listens, and answers in real time
You ask a question → it understands → it answers → it speaks, with natural movement and lip sync. Fully customisable in content, behaviour and appearance — ideal for reception desks, demonstrations and information points.
Demonstrated at Tête Défense, Paris — 16 April 2026.
Turnkey integration of the systems needed to create an interactive video avatar that can answer questions. The result is an avatar that speaks naturally, with lip synchronisation and coherent movement.
-
1
The visitor speaks
Someone asks a question out loud at the kiosk.
-
2
Speech to text
The audio is transcribed into text.
-
3
The AI reads it
The text is analysed by an AI model.
-
4
An answer is written
The AI generates a response from its instructions and knowledge base.
-
5
The avatar replies
The answer is turned into speech and rendered into a realistic avatar video.
Technical architecture
The system is made of two parts:
- The kiosk — the physical unit: a Raspberry Pi base, screen, microphone and enclosure.
- An application server that handles the integration of the different components.
The end interface simply runs in a web browser, which keeps the kiosk itself simple to deploy and replace.
Customisation
The avatar can be configured with:
- Specific instructions
- Behaviour rules
- A dedicated knowledge base
That is what makes it answer as your organisation rather than as a generic assistant.
Video & avatar production
The avatar video is replaceable, and can be produced to order. The process relies on:
- Motion capture of head movement and expressions
- A text read-through used for lip synchronisation
- Silent sequences that cover the natural transitions between answers
Key points
- Turnkey solution
- Simple interface — it runs in a browser
- Customisable avatar: content, behaviour, appearance
- Suited to reception desks, support, demonstrations and information points
