Mistral AI's Chat: The French AI Champion of Data Protection
The artificial intelligence race is no longer limited to technical performance. In 2025, personal data protection has become a determining factor in choosing your AI assistant. Incogni's groundbreaking study overturns preconceived notions: contrary to American giants, it's a French solution that takes the crown for confidentiality.
The stakes are major: with over 180 million active ChatGPT users and the explosion of AI chatbots, understanding how these tools handle our data becomes essential. This detailed analysis reveals the surprising results of the first comparative study on privacy protection of major conversational AIs.
The Incogni 2025 Study: A Rigorous Methodology to Evaluate AI Confidentiality
The 11 Data Protection Evaluation Criteria
Incogni, a company specialized in personal data removal from the web, has developed an unprecedented analysis framework. Their study "Gen AI and LLM Data Privacy Ranking 2025" evaluates 9 major chatbots according to 11 specific criteria:
Transparency and data collection:
- Sources used to collect user data
- Types of data collected by AI applications
- Clarity and readability of privacy policy
- Ease of finding information about model training
Data usage for training:
- Use of user conversations to train models
- Data used to train initial models
- Transparency about prompt usage for improvement
- Ability to opt out of personal data usage
Sharing and protection:
- Sharing messages with third-party providers
- Global data sharing with third parties
- Removal of personal information from training datasets
The 9 AI Chatbots Analyzed
The comparative study covers the main market solutions:
- Mistral AI - France
- ChatGPT (OpenAI) - United States
- Claude (Anthropic) - United States
- Copilot (Microsoft) - United States
- Gemini (Google) - United States
- Grok (xAI/Elon Musk) - United States
- Meta.ai (Meta) - United States
- Pi (Inflection AI) - United States
- DeepSeek (DeepSeek) - China
Mistral AI's Le Chat: Why the French Solution Dominates the Ranking
A Unique Positioning on Data Protection
Mistral AI's Le Chat rises to the top of the ranking thanks to a differentiated approach to confidentiality. Unlike American tech giants, the French startup has made data protection a major competitive advantage.
Strengths identified by the study:
- Limited personal data collection
- Exemplary transparency on data usage
- Easy opt-out for users regarding data training
- Strict compliance with European GDPR
The Competitive Advantage of GDPR Compliance
Mistral AI's European position constitutes a decisive asset. Private infrastructure deployment allows companies to maintain total control over their sensitive data, avoiding transfers to jurisdictions with less strict regulations.
This approach perfectly addresses the concerns of organizations subject to strict regulatory constraints, particularly in banking, medical, or governmental sectors.
The Privacy Podium: ChatGPT and Grok Complete the Top 3
ChatGPT: Transparency as Strength
Despite its global leadership position, OpenAI's ChatGPT ranks second, notably thanks to its transparency regarding user prompt usage. The study emphasizes that ChatGPT is "the most transparent product concerning prompt usage to improve its artificial intelligence."
This transparency contrasts with other solutions that remain vague about their training practices.
Grok: The xAI Surprise from Elon Musk
Grok, xAI's chatbot, completes the podium in third position. This unexpected performance is explained by Elon Musk's architectural choices, who integrated enhanced protection mechanisms from the design phase.
The Poor Students: When Giants Disappoint
Meta AI, Gemini, and Copilot: A Disappointing Trio
The study reveals a troubling reality: tech giants' chatbots (Meta AI, Google Gemini, Microsoft Copilot) occupy the last places in the ranking.
Main identified deficiencies:
- Absence of means to refuse prompt usage (Gemini, Meta AI)
- Complex and poorly accessible privacy policies
- Extensive data collection without sufficient transparency
- Opaque sharing with third-party partners
DeepSeek and Pi AI: Persistent Gray Areas
DeepSeek and Pi AI also present significant gaps, particularly regarding users' ability to control the use of their personal data for model training.
Practical Implications: How to Choose Your AI Chatbot in 2025
Selection Criteria for Individuals
For personal use, prioritize:
- Mistral AI's Le Chat for maximum confidentiality
- ChatGPT for performance/transparency balance
- Avoid tech giants' solutions if privacy is priority
Recommendations for Businesses
For professional deployment:
- Regulated sectors: Mistral AI's Le Chat is essential
- General usage: ChatGPT remains viable with appropriate settings
- Absolutely avoid: Meta AI and Gemini for sensitive data
Configuration and Best Practices
Whatever your choice:
- Consult and adjust privacy settings
- Limit sharing of sensitive personal information

The Future of AI Privacy: Trends and Perspectives
Regulation as Innovation Driver
The European AI Act and national regulations increase pressure on AI actors. European solutions like Le Chat benefit from a structural advantage in this compliance race.
The Emergence of a New Competitive Paradigm
Differentiation no longer relies solely on technical performance. Data protection becomes a major competitive advantage, particularly for conquering European markets and sensitive sectors.
Frequently Asked Questions About AI Chatbot Privacy
Is Mistral AI's Le Chat really safer than ChatGPT?
According to the Incogni 2025 study, Le Chat indeed presents better privacy guarantees, notably thanks to its native GDPR compliance and private deployment options. However, ChatGPT offers superior transparency about its practices.
Can we trust free chatbots with sensitive data?
The study demonstrates that free doesn't guarantee privacy. Meta AI and Gemini, although free, rank among the least privacy-respectful. Always prioritize solutions with explicit guarantees.
How to verify an AI chatbot's privacy practices?
Systematically consult the privacy policy, check data setting options, and look for compliance certifications (GDPR, ISO 27001). The Incogni study also provides a reproducible evaluation framework.
French Excellence Serving Privacy
The Incogni 2025 study marks a turning point in AI chatbot evaluation. Mistral AI's Le Chat proves it's possible to reconcile technical performance with privacy respect, offering a credible alternative to dominant American solutions.
This French success highlights the growing importance of data protection in AI tool selection. For privacy-conscious users and businesses, this study provides a valuable guide to navigate the complex ecosystem of conversational artificial intelligence.
The future belongs to solutions that can balance innovation and data protection. Mistral AI's Le Chat shows the way, but competition intensifies. Stay vigilant and informed to make the best technological choices.
