Abstract

This study presents a comparative analysis of four generative Artificial Intelligence (AI) platforms in the correction of 100 essays in the ENEM, which were awarded a score of 1000 by official INEP evaluators. The objective was to evaluate four different platforms for correcting essays with maximum scores and compare these evaluations with the official evaluation, which assigned maximum scores to all of them. The methodological approach included the creation of a database with the themes and texts of the one hundred essays, the creation of scripts for interaction with the platforms, and the storage of the results with feedback for each essay, based on official criteria, for subsequent analysis of the results. Descriptive statistics and inferential statistics were used for the analyses, using ANOVA and Tukey tests. The results pointed to the Brazilian platform Maritaca IA as the one that obtained the best results, with scores closest to those assigned by ENEM evaluators, suggesting its use in applications in which the Portuguese language and Brazilian context must be considered.
