Why it matters

Real sources, not invented ones.

A general-purpose AI assistant can go wrong exactly where a lawyer cannot afford it: the sources.

The risk

On its own, the assistant can make things up.

It can cite laws and judgments that do not exist. In a pleading or an opinion, an invented reference is a mistake that falls on whoever signs it.

With Lidia

Every reference that comes from Lidia comes from a real source.

Legislation, case law and guidance come from the legal research Lidia carries out on official sources. They are always cited and verifiable: you open them and can consult them directly.

Official sources. Legislation, case law and guidance, up to date.

Always cited. The answer always shows the official sources.

Open to check. Open and verify the full texts of the official sources.

What you can do from the chat

Search legislation

Laws and codes from official sources, up to date.

Search case law

The relevant judgments, with the reference.

Query documents

Questions on the papers in a matter, with Smart Answer.

Start a workflow

Save to matters

How to use it

In the assistant’s chat, just mention Lidia in your request. Lidia searches, works on your documents and hands the result back to the assistant with the references. The assistant carries on from there.

«Lidia, research the Court of Cassation’s case law on dismissal for just cause.»
