We build the legal AI that lawyers deserve

Not a generic AI with a lawyer prompt. A real legal AI: official corpus, no hallucinations, 99.3% on the Bar Exam (144/145) and 98.4% on the Judiciary Exam (253/257).

Why Lexiel exists

Spanish-speaking lawyers don't need a generic AI. They need an AI that understands the difference between an appeal and a cassation, knows what the Supreme Court says about limitation periods, and cites the Official Gazette with exact date and number.

Lexiel was born from that frustration. We were lawyers who used ChatGPT for legal research and got tired of the hallucinations, invented citations, and articles that didn't exist. So we built it ourselves.

Our principles

Anti-hallucination by design

Every Lexiel answer cites the exact source: article, ruling, or official gazette. If it's not in the official corpus, Lexiel says so. No fabrications.

Real legal specialization

We are not ChatGPT with a lawyer prompt. Lexiel understands normative hierarchy, Supreme Court jurisprudence value, and the difference between cassation and appeal.

Spanish-speaking coverage

Spain, Mexico, Colombia, Chile, Argentina, Peru and 15 more countries in a single system. 21 jurisdictions, 2,550,000+ provisions, complete LATAM coverage.

Benchmark transparency

We publish our benchmark methodology openly. 99.3% on the Bar Exam (144/145), 98.4% on Judiciary (253/257), combined 98.8%. 100% on Mexican bar (30/30). Verified, not estimated.

Live and updated corpus

We update the corpus when the law changes. Official Gazette same day, CENDOJ weekly, EUR-Lex in real time. An AI that doesn't know current law is useless.

GDPR by default

EU servers, no training on your data, no data sharing with third parties. For lawyers handling sensitive client information, this is non-negotiable.
