Lexter.ai provides an AI-powered virtual legal assistant for Brazilian law firms, focusing on automating operational and technical legal tasks to increase efficiency and enable lawyers to win more cases. It offers a virtual legal specialist (Laura) and a relationship specialist (Lia) to handle processes, document automation, and client communications. The product is presented as a single-plan solution with 24/7 operations, real-time process tracking, and automated drafting and jurisprudence search capabilities.

Laura automates operational and technical legal tasks such as drafting documents (petitions, contracts, notices), analyzing jurisprudence, and summarizing complex documents. Laura tracks process updates in real time, delivers organized interview and hearing scripts, and provides strategic suggestions based on processed data. Lia handles client communications via email and WhatsApp, conducts lead qualification, answers client questions, routes complex requests to human teams, and (soon) generates contracts and power of attorney documents. The offering is presented as an all-in-one plan with fixed pricing, including 24/7 workload coverage, automated process monitoring, and advanced contract and notification drafting within a single subscription.

Pedro CalderonFounder

I've studied naval engineering at USP, in Brazil, in my graduation year I discovered that I liked programming much more than I liked boats! Shortly after as a developer at RevMob I discovered a new passion, creating products. In 2016 I created my first startup eDoc, a health tech with the mission to optimize inefficiencies in the Brazilian health care market, focusing in patients primary care. Finally in 2020 I joined the Lexter.ai founding team to try to change the Brazilian lawtech scene.
