Lexroom puts the lawyer in the chat

On 10 November, Lexroom launched lex, an AI personal agent for lawyers that lives in WhatsApp. Not a chatbot bolted onto a legal database. The company describes it as a way to bring its whole operating system into the messaging app a lawyer already has open on a phone.

The timing is deliberate. Lexroom spent September buying Query Juriste in France and Praven Intelekt in Bulgaria. Its own account of those acquisitions says the two teams brought local legal data, local expertise and roughly 1,200 subscribed firms. The new agent is the next layer: one interface across five European markets, but with the local legal machinery underneath.

lex watches email, calendars, clients, matters and documents. It can receive a forwarded client message, create the client and case in Lexroom, check free slots and suggest an appointment. A lawyer can send it a PDF and a voice note, ask for research in the context of a matter, and get back a short summary plus the full research as a PDF. It can prepare a first draft. It can also answer an email from its own address and say that an AI wrote it.

The useful feature is the brake

Every action follows the same rule: lex proposes, the lawyer decides. No email is sent, no appointment is booked and no document is filed without approval. The agent can monitor a calendar every fifteen minutes and surface a moved hearing, but it does not quietly rearrange the day.

That makes this less like an assistant with a personality and more like a permission layer for a legal system. The WhatsApp message is the quick part. The important part is the hand-off back to the professional before anything consequential leaves the building.

Lexroom’s launch page gives a good example. A lawyer can reply “ok to Esposito, at 17:00” to a proposed appointment. lex prepares the response, shows it, and only sends it after confirmation. Later, between hearings, the lawyer can forward an opposing party’s PDF and a thirty-second voice note. The agent files it, starts the research and leaves the draft waiting for review.

There is a quiet product claim here that is stronger than “AI for lawyers”: useful autonomy is not the same as unsupervised autonomy. In a profession built around client confidentiality, deadlines and sign-off, the pause is not a missing feature. It is the feature that makes the rest of the system plausible.

The launch is closed beta and has no public price yet. Lawyers can join a waiting list. That matters. lex is asking a regulated profession to let a new participant watch the inbox, calendar and case files, while still keeping the final click with the human. A waiting list is a small promise compared with that trust boundary.
