Problem
The increasing accessibility of generative AI tools presents a significant challenge to academic integrity, making it difficult for educators to verify the authenticity of student submissions. Traditional plagiarism detection methods are insufficient to address AI-generated content, potentially devaluing educational degrees and undermining fair assessment practices.
Solution
Norvalid provides an Authorship Validation platform designed to confirm the originality of student writing through advanced linguistic analysis and psychometric testing. The system establishes a "student voice" fingerprint by comparing submissions against a student's authenticated writing samples. This approach moves beyond AI detection, focusing instead on validating the author's original contribution. By integrating with Learning Management Systems (LMS) via LTI 1.3, Norvalid offers a seamless workflow for educators to assess the authenticity of student work and maintain academic standards in the age of AI.
Target Audience
Norvalid's primary customers are educational institutions, including universities and colleges, seeking to uphold academic integrity and ensure the authenticity of student work in their assessment processes.
