An AI that does not just translate: it understands the law
Where generic tools translate text, Lexa reproduces the exact terminology of each branch of law. An architecture trained exclusively on law, built for professionals who cannot afford approximation.
Four stages of training, one single goal: legal accuracy
Each layer of training moves Lexa further from the general-purpose translator and closer to the legal expert.
Legal training
Lexa learns the law before it translates. Its foundation is real legal documents, aligned language by language, so it grasps the meaning of a term in its legal context, not in its everyday sense.
Specialised training
Rather than a single model, Lexa relies on separate engines, each an expert in one area of law. A commercial contract and a criminal document are not handled by the same brain.
Terminological training
The expressions specific to each branch (commercial, tax, intellectual property, criminal law) are checked and validated by legal linguists, not by an algorithm left to its own devices.
Official glossaries
The reference glossaries of the institutions are applied automatically to every translation, for perfect terminological consistency from one document to the next and from one matter to the next.
Expert terminology across 14 areas of law
Each area relies on a specialised engine and its own terminology, validated for your most technical documents. Choose yours to see the dedicated expertise.

Lexa Quality: accuracy, but under your control
Every translated segment gets a quality score that shows you at a glance which passages to check first. You keep control of what actually matters, without rereading the whole document line by line.
And when the stakes demand it (a closing, litigation, a document that will be relied on), a review by a Legal 230 legal expert remains available as an option. Lexa speeds up the work of legal professionals; it never decides in their place.

Lexa's AI expertise, plainly put
What is Lexa's AI trained on?
Lexa is trained exclusively on 60 million legal documents aligned across more than 40 languages. On top of that legal training come 14 engines specialised by area of law, terminology validated by legal linguists and more than 900 official glossaries (CJEU, WIPO, ILO) applied automatically.
Why does a specialised AI translate law better than a general-purpose tool?
A general-purpose tool translates the everyday sense of words; it does not know a jurisdiction's official terminology or the conventions of a branch of law. Lexa was trained only on legal corpora, with engines dedicated to each area and reference glossaries built in, which guarantees exact terminology, consistent from one document to the next.
How does Lexa guarantee the accuracy of every translation?
Every translated segment gets a quality score (Lexa Quality) flagging the passages to check. For the highest stakes, a review by a Legal 230 legal expert remains available as an option. Lexa speeds up the work without ever taking control away from the legal professional.
Which areas of law does Lexa cover?
Lexa covers 14 areas: corporate law, commercial law, contract law, competition law, tax law, banking and finance, intellectual property, employment law, real estate law, international arbitration, litigation, criminal law, immigration and public law. Each area relies on a specialised engine and its own terminology.
How many languages does Lexa support?
More than 40 languages, all specialised in law: every European Union language, UK and US English, Arabic, Chinese, Japanese, Russian, Turkish, Ukrainian and many more.
Does Lexa replace a human legal translator?
No. Lexa makes legal translation independent and instant for everyday work, at a high level of accuracy. When a translation engages your liability (sworn translation, complex matters, rare languages), Legal 230, the agency that builds Lexa, takes over with expert translators.
