About Axel

I work at the intersection of language, quality, and generative AI.
Since 2019, I have been running an independent business focused on the structured analysis and validation of complex content.
With the increasing integration of AI into products, a question has arisen:
What is a generative system truly worth when deployed at scale in the French market?
Today, I support product teams and companies integrating generative models to audit the linguistic and structural robustness of their systems.

I don't correct texts.
I evaluate behaviors.

•Where do hallucinations appear?
•Do prompts remain stable when faced with edge cases?
•What legal or reputational risks remain invisible at first glance?
•Is there a gradual drift in meaning or tone?
•Does the system hold up under pressure?

My approach is methodical, test-oriented, and focused on risk reduction.
Objective: identify weaknesses before they become visible to your users.

If your product generates content in French at scale, I can help you measure its real robustness, beyond appearances.
