Project Title: TextLens AI: An Intelligent Multi-Layer Textual Similarity Detection Platform for Academic Integrity Enforcement
Description:
TextLens AI is a self-contained web platform that addresses the high cost, limited Arabic support, and data privacy concerns of commercial plagiarism detection tools like Turnitin and Copyleaks. The platform is powered by TextLens V2, a six-layer similarity detection engine combining Exact Match, Near-Exact Normalization, Multi-Window N-gram Shingling (window sizes 3, 4, 5, 7), Dice Coefficient, Jaccard Similarity, and space-optimized Longest Common Subsequence analysis within a weighted scoring formula with boosting rules to minimize false negatives. A dedicated seven-stage Arabic text normalization pipeline detects and neutralizes Arabic-specific evasion techniques including character substitution, diacritical marks, and zero-width Unicode injection. Beyond detection, TextLens AI provides a fully integrated ecosystem covering assignment creation, submission, automated similarity analysis, grading, email notifications, analytics dashboards, and Excel/CSV report export. The system operates entirely server-side without paid external APIs, achieving 100% detection of verbatim and formatting-manipulated copies, with a six-layer security architecture (Rate Limiting, HSTS, SQL/XSS detection, JWT, PostgreSQL RLS, Zod validation). Built with Next.js 16, TypeScript, React, and Supabase PostgreSQL, the platform offers a $0 self-hosted alternative to $3,000–$15,000 annual commercial licenses, directly supporting SDG 4 (Quality Education) for Iraqi universities.
