One need.
A world of possibilities.

Explore three ways to transform your tools.
Your work is always the starting point.

01 / KNOWLEDGEExample workflow

Make your knowledge accessible.

Find a procedure, search documentation or draft a reply: an assistant grounded in your sources, with your team’s permissions.

The right access.
Only where it is needed.

Connecting AI does not mean opening everything to it. Users, sources and permissions are part of the project from the start.

A defined data scope

Information that serves the task, rather than collection by default.

Permissions tailored to roles

Access is determined by each team’s responsibilities.

Our product · Moon AI

Multiple models.
One workspace.

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.

The Moon Blur concept

Expose less.
Define clearer boundaries.

Example contentIllustrated masking
Prepare a message for[PERSON_01]about case[CASE_01]. Adresse de contact :[EMAIL_01].

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.

Before you begin

Clear answers.
No jargon.

You don’t need to arrive with a technical architecture. A practical need is enough to get started.

All frequently asked questions
How do we know whether AI is relevant to us?

We 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.

Can you work with our existing tools?

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.

Does all data stay in France?

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.

What budget and timeline should we expect?

They depend on the scope, required integrations and security requirements. The first conversation establishes constraints before we propose a quote and schedule.

Can we start with a small project?

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.
