**5. Conclusions, Challenges, and Opportunities**

In short, from the comparison of the two terms studied, there is no clear difference between the two terms, although it has been observed that there is a greater tendency to use Legaltech in the USA and Lawtech in the UK.

According to the databases analyzed and summarizing everything studied above, Legaltech is the most widespread and oldest concept; its most common use refers to the use of technology to provide legal services and aims to increase the effectiveness of the services provided. From 2015 onwards the variant of Lawtech arises.

Legaltech as reflected in the scientific literature is a considerably more holistic concept and is associated with the incorporation of new technologies such as artificial intelligence or machine learning, while Lawtech is more focused on the legal sector itself. Thus, it is common to associate Lawtech to technologies or tools that aim to help the legal sector, while Legaltech also encompasses the development of tools such as artificial intelligence, machine learning, or natural language processing. In view of the results found in the scientific literature, and for better searchable indexing in scientific databases related to this scientific field, it is proposed to use the term Legaltech to include all technological advances in the legal area, i.e., Legaltech is a concept that encompasses Lawtech.

The greatest challenge of this study is that the legal professions are undergoing major changes with the introduction of the new technologies, which will transform the sector, requiring it to become reinvented. In addition, legal knowledge has a number of features that facilitate its digitization and automation, in fact, it has been seen to be the precursor of scientific fields such as bibliometrics, and even bibliometric indicators of citation index measurements. It is therefore not understandable how this issue has been left aside for so long, perhaps because now with the era of communications is the right time.

As drawbacks, one can cite that on the one hand legal technology tools can also pose risks, especially because of the biases perpetuated by algorithms. As well, from a legal perspective, ensuring that the ethical issues surrounding legal technology are fully considered. As in other sectors, there is a potential for a dangerous concentration of Legaltech in high-tech industries. As in other sectors, there could be a dangerous concentration of Legaltech in high-tech industries that consider it a great business potential, therefore it is necessary that the law continues to ensure antitrust regulation as it does in the USA and the European Commission.

From the point of view of opportunities, artificial intelligence-based systems can provide accurate legal advice and analyzing large amounts of data that law firms and legal advisors will use to improve their management and increase their productivity. Therefore, this technology should be applied in the administrative and civil fields, as well as in those that speed up the administrative process. Like other technological advances, these will reduce legal costs and thus improve universal access to justice.

In short, Legaltech and Lawtech offer us the opportunity and challenge to promote a just and equitable society, and to empower individuals. Thus, giving greater access to legal services and the possibility of achieving the goal of universal access to justice.
