Italian-founded legal AI company Lexroom has launched lex, an AI-powered personal assistant for lawyers accessible through WhatsApp, just two months after acquiring Bulgarian legal tech company Praven Intelekt. The new product aims to help legal professionals manage administrative tasks, conduct legal research, and prepare documents directly through a messaging app.

The launch marks another step in Lexroom’s expansion into the Bulgarian market, following its September acquisition of Praven Intelekt. The company is positioning lex as a legal AI agent designed to move beyond answering questions and take on everyday tasks, subject to lawyers' approval.

Available in closed beta from November 10, lex is initially being introduced in five European markets: Bulgaria, Italy, Spain, Germany, and France.

Unlike conventional legal AI tools that require users to access a dedicated platform, lex operates through WhatsApp, allowing lawyers to interact with the assistant using text messages and voice notes.

The product targets solo practitioners and small to medium-sized law firms, where lawyers often handle administrative responsibilities alongside their legal work.

According to Lexroom, the assistant can monitor emails, calendars, client communications, and case files to identify tasks requiring attention. It can also suggest meeting times, schedule appointments, conduct legal research, and prepare initial document drafts.

For example, a lawyer moving between court hearings could request a summary of urgent emails and upcoming deadlines or ask the assistant to research a legal question and prepare a draft for later review. The system is designed around a human approval process: lex can recommend actions, but nothing is sent, scheduled, or filed without the lawyer's authorization.

“AI is finally becoming proactive. With lex, it goes from answering your questions to working for you,” said Paolo Fois, co-founder and CEO of Lexroom.

“Every Lexroom customer can now run their practice with the kind of back-office support that, until now, only large law firms had the resources to provide.”

Lexroom says the new assistant is integrated with its existing legal AI platform, which connects to more than 16 million verified and curated legal sources.

This infrastructure allows lex to combine legal research and document drafting with information about a lawyer's clients, cases, and ongoing work.

The company also emphasizes that its drafting templates and workflows have been developed by in-house legal professionals rather than relying exclusively on general-purpose AI models. By integrating these capabilities into WhatsApp, Lexroom aims to make legal AI more accessible to smaller practices that may lack dedicated administrative or research teams.

However, the product remains in closed beta, and lawyers can join the waitlist to be the first to hear about the official release. lex will also be available in additional messaging apps in the near future.

Lexroom's expansion into Bulgaria and beyond

The launch follows a period of growth and international expansion for Lexroom. In May 2026, the company raised $50 million in a Series B funding round led by Left Lane, with participation from Base10 Partners, Eurazeo, Acurio Ventures, Entourage, and View Different.

Lexroom reports that it has since surpassed €30 million in annual recurring revenue (ARR), serves more than 20,000 customers, and employs over 300 professionals.

Its acquisition of Bulgarian legal tech company Praven Intelekt in September, alongside French company Query Juriste, marked the company's first acquisitions and expanded its presence to five European markets.
