The Error Analyzer is conceived as a versatile tool for the academic and pedagogical community, providing methodological support for the systematic study of texts where variation, correction, or revision is the focus of analysis. Unlike tools designed for comparing unrelated texts, it is optimized for paired data: an original version and its modified counterpart, whether erroneous and corrected, draft and final, or student and instructor-revised. Its design responds to the needs of several key user groups:
Linguists and Researchers
For scholars investigating language acquisition, error typologies, or revision practices, the application facilitates rigorous examination of textual variation. By aligning original and revised versions of the same text, it enables systematic identification of changes, supported by structured annotation and AI-assisted insights. This approach is especially suited to error analysis, developmental studies, and the study of textual improvement over successive drafts, all within a framework that prioritizes replicability and methodological precision.
Educators and Teachers
In educational contexts, the application provides a robust means of diagnosing learner difficulties and identifying recurrent error patterns. By working directly with student texts and their corrected counterparts, teachers can ground their feedback in systematic evidence. The tagging system and reporting functions generate data-driven overviews of error types and frequencies, supporting both individualized guidance and curriculum-level interventions. This allows assessment to move beyond impressionistic judgments toward more empirical, transparent, and pedagogically valuable practices.
Students
For learners in linguistics, applied language studies, or related disciplines, the application serves as both an analytical tool and a training environment. By engaging with paired texts such as their own drafts and revisions or curated examples, they acquire experience in systematic annotation, close textual comparison, and the critical interpretation of variation. This hands-on practice develops analytical competence, enhances methodological awareness, and prepares students for independent research or professional tasks involving text analysis.
