Lexter.ai

Lexter is a Brazilian legal automation platform that gives a law office two AI specialists. Laura handles the legal work: monitoring cases in real time and sending automatic alerts when something moves, drafting petitions, contracts and notifications, researching jurisprudence, summarizing documents and preparing settlement proposals, opinions and interview or hearing guides. Lia handles the client side: answering the office's WhatsApp around the clock through the official Meta API, qualifying leads, assisting with sales and keeping clients informed. It is aimed at Brazilian lawyers and firms of any size, from solo practitioners to offices with dozens of attorneys, and the specialists are trained on the demands of Brazilian law. Everything runs in Portuguese and the case monitoring is built around the Brazilian court system. Contract and power of attorney automation is listed as coming soon. Pricing is published as a single plan. Lexter Essencial costs R$199 per month and includes all current capabilities of both specialists, with signup available directly on the site without a sales call. The company is backed by Brazilian venture funds and describes itself as one of the earliest applications of AI to law in the country.
