Lex — legal & notarial

Lex is the KlusAI product for legal and notarial practices. It keeps your clients, case files, engagements and deadlines in one place, connects your litigation to portal.just.ro, and lets you ask questions about your own documents and about Romanian legislation — with answers that cite the passages they came from, so you can check them.

Lex opens in Romanian. You can switch to English on your Account page; the assistant then answers in English too.

The assistant

Lex’s assistant is Klu, the same assistant that runs across the kOS platform. In Lex it appears in the sidebar as Ask Lex, and its toolkit is scoped to legal work: it can search your clients, case files, deadlines and portal change history, and search Romanian legislation, Constitutional Court decisions and the documents your firm has uploaded.

The lawyer stays responsible

Klu is an assistance tool. Answers are AI-generated and can be incomplete or wrong, which is why every answer carries citations and a grounding badge — open the source and confirm it says what the answer says before you rely on it, send it to a client, or file it. Responsibility for legal acts, strategy and advice remains with the lawyer.

Where Lex sits

Lex is one of the products built on kOS — see What is kOS? for the shared parts: sign-in, organizations, roles, knowledge bases and the assistant. The other products are Med for clinics and razorBridge for EU compute.

Common questions — data location, accuracy, what legislation is included, whether Lex replaces portal.just.ro — are answered in the FAQ.
