Artificial intelligence is a field of computer science that enables a machine to simulate human intelligence. Over the past several years, advances in AI have enabled numerous applications across various fields, including law.
In this article written by the Yiaho team, we will explore how artificial intelligence can help solve legal problems using its knowledge of the law, and also point out its limitations.
Artificial intelligence for law
Artificial intelligence has become a daily tool for thousands of lawyers, corporate legal counsel, and notaries.
On our Yiaho platform, which is completely free, we provide an “AI Lawyer” specifically designed for French and European law. It saves valuable time on all repetitive tasks while respecting professional confidentiality and ethics.
What is a legal AI?
A legal AI is an assistant that combines the power of large language models with constantly updated databases: case law, legislative texts, legal doctrine, and standard contracts.
It can search, analyze, synthesize, and draft documents with precision far superior to traditional manual research. It does not replace the lawyer; it eliminates everything that can be automated without loss of quality.

Yiaho’s AI Lawyer: designed for French speakers
The AI Lawyer available on Yiaho has been specifically trained on French and European law. It is hosted in France, making it fully compliant with GDPR and professional confidentiality. No data is retained after the session and you don’t need to install anything: everything happens in your browser. And most importantly, access is 100% free, with no limit on questions or documents, because we believe that access to law should be facilitated, not monetized.
How does it work in practice?
You ask your question in natural language or directly upload your document (contract, summons, judgment, etc.).
The AI reads everything, cross-references official sources (Legifrance, Dalloz, Court of Cassation, CJEU, etc.) and returns a clear answer in seconds, with precise references and, when useful, a proposed text ready to be adapted.
A concrete example: you upload a commercial lease. The AI immediately identifies potentially abusive clauses, reminds you of applicable recent case law, and proposes three formulations compliant with the Pinel law and recent rulings.
The advantages of AI in law
AI in law offers several advantages to legal professionals and their clients. It can help speed up legal research by providing accurate analyses and quickly accessing relevant precedents. It can also help reduce errors and omissions when drafting legal documents by providing clear and precise suggestions.
Finally, it can help reduce costs for clients, as it can handle many legal tasks without requiring human intervention.

What it really changes on a daily basis
Case law research becomes ten times faster. The first version of a contract or brief is drafted in minutes instead of several hours. Document review almost systematically reveals risks that could have gone unnoticed. Formatting errors or omissions of recent precedents decrease significantly.
Small firms and independent practitioners finally offer services at the level of large firms, without multiplying billable hours.
What AI will never do for you (the limitations of AI for law)
An artificial intelligence, however powerful, does not replace human judgment, procedural strategy, client listening, or courtroom advocacy.
It does not feel empathy and does not bear final responsibility: it is always the lawyer who signs and assumes liability. It is sometimes subject to hallucinations (rare but possible), which is why you must systematically verify the sources it cites.
It must be fed with quality data: the more specialized the tool is in French law, the lower the risk of errors or bias.
AI in law is limited by the data on which it is trained. If the data is biased or incomplete, the AI can produce inaccurate results. As we often repeat on Yiaho, “Our artificial intelligences can make mistakes. It is essential to always verify the information!”
