Put your AI to work.
Connect your documents, find information, assist your team or automate tasks. We integrate models with your tools and adapt them when your requirements call for it.
AI models, Moon AI, applications and business integrations. From Pont-Audemer, Stellarr Studio works with organisations across France, placing data control at the heart of every project.
Applied AIBespoke productsData under control
Our product Moon AI, alongside open technologies that help you choose your hosting, understand your systems and plan their future.
Train, evaluate, integrate and deploy: we connect models to real uses. Moon AI and Moon6 offer a glimpse of what we build.
Available versions, capabilities and a command to get started.

View the productAn internal assistant, a business application or a process to automate. We start with your needs to choose the right technical solution.
Connect your documents, find information, assist your team or automate tasks. We integrate models with your tools and adapt them when your requirements call for it.
From internal applications to customer-facing services, we design user journeys, develop interfaces and connect them to your information systems.
Hosting, access rights, data flows and retention: we define an architecture suited to your organisation and its constraints.
Explore three ways to transform your tools.
Your work is always the starting point.
Find a procedure, search documentation or draft a reply: an assistant grounded in your sources, with your team’s permissions.
A knowledge base
Defined sources and access
Inside your team’s tool
Connecting AI does not mean opening everything to it. Users, sources and permissions are part of the project from the start.
Information that serves the task, rather than collection by default.
Access is determined by each team’s responsibilities.
Providers, processing and hosting explained.
Moon AI brings AI models together in one platform. With Moon Blur, Stellarr also develops tools to mask sensitive data before it is sent to third-party models.

Concept mock-up with fictional data and predefined replacements. This is not the Moon Blur engine. Reversible masking alone does not amount to irreversible anonymisation.

You don’t need to arrive with a technical architecture. A practical need is enough to get started.
All frequently asked questionsWe start with a use case: finding information, processing documents or supporting a team. Conventional automation may sometimes be more suitable. Defining the scope helps choose the right approach without imposing AI.
Yes, depending on their integration capabilities. We examine APIs, code, data formats and access rights to identify what can be connected or needs to change.
That should not be assumed. Where a service is hosted and where a model processes data are separate questions. We specify the data flows and selected providers. Moon AI’s DPA lists providers in France, the EU and outside the EU.
They depend on the scope, required integrations and security requirements. The first conversation establishes constraints before we propose a quote and schedule.
A prototype or an initial use case can help assess the solution’s value before a broader rollout. We define its scope and acceptance criteria together.
