gensai.aiAI agency in Paris
Based in Paris, Gensai works with clients all over France
Gensai is an AI agency based in Paris, in the 10th arrondissement. It designs, builds and puts into production AI agents, chatbots and answer engines, voice AI solutions and custom developments, and works with clients all over France. Every project starts with a first use case validated in 2 to 3 weeks on real data.
An AI agency in Paris, from the workshop to production
An artificial intelligence project starts with a conversation: understanding the business, spotting the task that costs time, looking at the documents and tools already in place. This scoping is done on site, at the client's premises, or by video call anywhere in France.
Gensai delivers solutions that work in the client's real conditions. The agency scopes the need, builds the solution, connects it to the data and tools in place, tests it on real questions and supports it all the way to production. Teams are trained to use it.
Hosting is in France or in Europe: for most projects with Scaleway or OVHcloud, two French cloud providers, and 100% in France when the client requires it. Depending on requirements, the solution can also run on the client's servers or locally, with no Internet connection. Open-weight models are preferred and client data is never used to train third-party models.

How a project unfolds
30-minute call
By video call, to understand the need, the data available and the constraints. A budget estimate is given at the end of the call.
Use-case workshop
Use cases are ranked by value and feasibility, at the client's premises or remotely. A first use case is selected.
First use case in 2 to 3 weeks
The solution is built on the client's data and tested on real questions. The results decide what comes next.
Production in 1 to 3 months
Integration with existing tools, hosting in France or in Europe, team training and long-term support.
In Paris and all over France: for which needs?
Communication and event agencies
The AI component of a brand activation, a stand or a seminar, as co-contractor or subcontractor: event chatbot, voice experience, interactive installation.
Museums, cultural venues and visitor sites
A character or an artwork that answers visitors out loud, in several languages, from content validated by the institution.
SMEs, mid-caps and large groups
A first use case chosen for its value and feasibility: answers to recurring requests, an internal answer engine, automation of a repetitive task.
Tourism, hotels and restaurants
An assistant on WhatsApp or an avatar on a screen in a reception area answers visitors about the activities, restaurants and practical information of a destination.
Firms and regulated professions
Assisted drafting of documents from supporting files, case analysis, a regulatory knowledge base that can be queried in natural language: sovereign tools for sensitive data.
Non-profits and foundations
Donation tracking, call analysis, AI awareness for teams: projects sized for controlled budgets.
Healthcare
Phone reception for a practice, automated reporting for a facility, patient information from validated content.
Public sector and local authorities
Use-case identification, feasibility studies and information assistants hosted in France.

Frequently asked questions
Why work with an AI agency in Paris?
To scope the project with people you can meet: an on-site workshop often brings out the right use case faster than a specification document. Gensai designs the solution, builds it and puts it into production, in Paris and all over France.
Where is Gensai located?
Gensai is based in Paris, in the 10th arrondissement, and has offices in Savoie, in La Toussuire. Discussions take place by video call or at the client's premises.
Does Gensai work outside Paris?
Yes. Based in Paris and present in Savoie, Gensai works all over France. Scoping and workshops take place on site or by video call, development and follow-up remotely. Distance changes neither the method nor the timelines.
How much does a project with an AI agency in Paris cost?
As a guide, at Gensai, a first use case on real data costs between €3,000 and €5,000 excluding VAT and takes 2 to 3 weeks. A first version teams can use costs between €5,000 and €10,000 excluding VAT, not including hosting and model usage, and going into production then takes 1 to 3 months. The amount depends on the integrations required. A 30-minute call is enough to scope the need and price it.
How do you choose an AI agency in Paris?
Four points are worth checking before choosing: detailed, verifiable case studies, the ability to put a solution into production and not only deliver a prototype, where the data is hosted and how the solution is tested before going live. Asking for a demonstration on your own documents remains the best way to judge. Gensai details twelve projects on its website and starts every project with a first use case on real data.
Does Gensai work with communication and event agencies?
Yes. Communication agencies, event agencies and studios entrust Gensai with the AI component of their projects, as co-contractor or subcontractor, and keep the relationship with their client. An event chatbot on WhatsApp, a voice experience in a public venue, an interactive installation: AI fits into the agency's creative project.
Where is client data hosted?
In France or in Europe, and 100% in France when the client requires it. For most projects, Gensai relies on Scaleway or OVHcloud. Depending on requirements, the solution can also run on the client's servers or locally, with no Internet connection. Data remains the client's property and is never used to train third-party models.
