AI for lawyers: using artificial intelligence without compromising legal rigour

AI for lawyers refers to the use of artificial intelligence in law firms: legal research, document analysis, contract review, matter summaries, drafting support and automation of repetitive tasks.

Silex is a Swiss legal AI platform designed by lawyers for legal professionals. It helps firms work faster on research and document analysis while keeping human supervision, professional secrecy and source verification at the centre.

Why law firms are interested in AI

Law firms handle growing volumes of documents: evidence, contracts, emails, case law, doctrine, internal notes and client communications. Generative AI can help summarise, compare, classify and prepare first analyses.

The goal is not to replace the lawyer. AI should reduce repetitive tasks so that more time can be spent on strategy, advice, argumentation and client relationships.

For a broader overview, see the AI for lawyers page.

Professional secrecy, data and sources

AI use in a law firm often involves sensitive data: procedural documents, contracts, personal information, trade secrets or litigation strategy. Before using a tool, a lawyer must know where data is stored, who can access it and whether it is used to train models.

Swiss sources such as Fedlex remain essential for verifiable legal research. The FDPIC also reminds organisations that Swiss data protection law applies to data processing involving AI.
