Increasingly, the adoption of artificial intelligence in the legal sector is no longer a distant trend but has become a concrete strategy for document management in law firms, corporate legal departments and courts throughout Brazil – thus integrating new solutions with modern regulatory bases, such as the General Data Protection Law (LGPD).
As digitalization advances, the need for efficiency, accuracy and agility in the management of legal processes intensifies. As a result, AI-based tools are being applied to operational and analytical tasks, providing a new level of performance in the legal environment.
From the simplest activities, such as monitoring deadlines, to complex tasks, such as automatic document creation, reveal both measurable and growing gains, boosting productivity, reducing rework, improving decision-making and allowing legal professionals to focus on more strategic and complex demands.
For this reason, we at ZapSign have prepared this special article on the subject. As you read, you will understand how artificial intelligence in the legal sector has transformed routines through applications such as task automation, jurimetrics, predictive analysis, intelligent document generation and other features that are redefining the role of legal professionals. Let's get to it!
Artificial intelligence in the legal sector: applications and impacts
Artificial intelligence has been driving substantial transformations in the routines and operational structures of the legal sector. As AI technologies become more sophisticated, their ability to handle large volumes of information, identify case law patterns, perform repetitive tasks more quickly and generate strategic insights based on historical data increases.
According to this recent study carried out by McKinsey, around 70% of organizations in major global regions have already incorporated artificial intelligence into their operations, integrating automated solutions into their business strategies. Among these companies, 65% incorporate Generative AI into their automation processes.
In light of this scenario, several technological applications have been adopted by law firms, corporate legal departments and Judiciary bodies with the aim of target to modernize workflows and respond more quickly and assertively to growing demands.
All these initiatives are valuable because, in addition to optimizing the time and resources used, they also promote transparency, standardization and legal security in legal operations.
Below, we highlight in depth the main uses and impacts of artificial intelligence in the contemporary legal context, highlighting how this technology has reconfigured traditional practices, expanded the process efficiency and transformed the performance of legal professionals.
Automation of repetitive tasks
One of the most direct applications of AI in the legal field is the automation of operational tasks. Processes such as contract analysis, identification of standard clauses, deadline control and document organization are now performed by intelligent systems, reducing the incidence of errors and saving time for highly qualified professionals.
The automation of repetitive tasks, such as drafting contracts and legal documents, has been facilitated by generative AI tools. According to McKinsey, Generative AI allows lawyers to focus on more strategic activities, while routine tasks are automated, increasing efficiency and reducing errors.
Tools like the Brazilian startup's AI assistant Lexter, a Brazilian startup supported by Y Combinator, exemplify this use. The platform automatically reviews contracts, suggesting changes based on previously registered models and allowing a analysis of documents in just a few minutes that would take hours to review manually.

According to data released by the company, the time savings provided by the use of technology can reach up to 70% in contract review tasks, significantly optimizing workflows and freeing up professionals for more strategic activities.
Jurimetrics and predictive analysis
Jurimetrics, or statistics applied to law, is gaining new momentum with artificial intelligence. Based on large volumes of court decisions, algorithms are trained to identify patterns and predict judgment behaviors, helping lawyers and managers make strategic decisions.
The project VICTOR, of the Federal Supreme Court (STF), is a reference in this field. Developed based on machine learning techniques, the system performs automated screening of extraordinary resources, identifying the presence of themes with general repercussions and significantly optimizing the process flow of the court.
Already in the Superior Court of Justice (STJ), the ATHOS project (Text Assistant with Hyperlinking and Semantic Organization) applies natural language processing techniques to organize decisions and summaries intelligently – which facilitates case law consultation and contributes to the standardization of decisions, increasing legal certainty.
Chatbots and automated service
Another relevant use of AI in law is the creation of legal chatbots capable of answering frequently asked questions, referring clients to lawyers and collecting preliminary information about cases. This technology speeds up the first contact with the client and allows professionals to focus on more complex analyses.
According to Gartner, large language models (LLMs) will increase legal department productivity by at least 10% to 20% more than previous transformative technologies. Adopting these systems reduces initial service time and helps build a more agile and accessible relationship with users.
Advanced legal research
AI tools have also been applied to legal research, optimizing searches in legislative, case law and doctrinal collections. Systems trained with NLP (natural language processing) techniques are able to understand the search intent and offer more relevant results organized by legal context.
According to Deloitte report, the use of AI in this context can reduce the time spent on preparing procedural documents by up to 60%, especially when combined with automatic legal content generators.
Creation of legal documents
Drafting legal documents such as petitions, contracts, opinions and notifications is one of the most costly steps in the legal routine. Tools based on generative AI have been transforming this process, allowing the creation of personalized documents based on information provided by the user.
Understand that, in addition to accelerating the production of legal documents, these tools also reduce the incidence of human errors and increase the standardization of documents, ensuring greater technical consistency and compliance with applicable standards.
Personalization is maintained through previously defined parameters, allowing texts to be adapted to the client's profile, area of activity or the firm's strategic positioning – which makes the process significantly more agile, in addition to being more aligned with the specific requirements of each case.
A McKinsey study points out that automating the creation of legal content with AI can improve productivity by up to 35% – which is particularly relevant in medium and large offices, which deal with a large volume of similar demands.

Challenges and regulations involved
Despite the benefits, the use of AI in law raises important debates about privacy, liability and technical quality. The LGPD establishes clear guidelines for the automated processing of personal data, requiring AI-based systems to guarantee the transparency and auditability of their decisions.
According to Gartner, one of the main concerns of legal leaders is data governance. The recommendation is that any system adopted undergo rigorous compliance assessments, including periodic audits, validation of results and human review of sensitive decisions.
Another point discussed is the ethical and professional responsibility for pieces created by AI. The lawyer remains the technical person responsible for the information, and it is necessary to validate the generated content to ensure that it complies with the legislation and the OAB codes of ethics.
It is a fact that the use of artificial intelligence in the legal sector has the potential to completely reshape the way offices, departments and courts operate – as long as the implementation is done carefully, with well-defined technical criteria, constant human supervision and compliance with the appropriate ethical and legal guidelines.
Evidence of this potential is revealed as modern tools such as VICTOR, ATHOS and Lexter have already demonstrated how technology can, in practice, be integrated in a structured and secure way into legal routines.
In today’s competitive environment, adopting AI-based solutions represents a strategic step towards responsible innovation and technical excellence.
