Silex is the AI-powered legal intelligence platform for professionals. Based at EPFL Innovation Park, we build the infrastructure layer on which lawyers, in-house counsel and public institutions search, reason, draft and manage legal knowledge with unmatched reliability.
Generic AI hallucinates, exposes confidential data and lacks legal reasoning. Silex solves this with a proprietary full-stack AI architecture built for legal precision, delivering source-grounded answers no generic model can match. Client data stays in isolated silos and never trains our models. We also integrate exclusive doctrinal content co-produced with legal scholars, a knowledge base no competitor can replicate.
Trusted by top Swiss law firms, private banks and public institutions. Partnered with bar associations.
