# ScholarScreen — Academic Plagiarism & AI Integrity Screening Engine

> ScholarScreen is an enterprise-grade academic document originality screening engine providing real-time multi-source plagiarism detection, stylometric AI content probability analysis, mathematical equation matching, and downloadable official PDF reports with zero-vault ephemeral privacy.

## Overview & Mission
ScholarScreen is designed for academic researchers, doctoral candidates, university faculty, journal editors, and higher education institutions. Unlike traditional plagiarism detectors that index submitted manuscripts into persistent repositories, ScholarScreen operates on a strict Zero-Vault ephemeral model: manuscripts are analyzed exclusively in isolated edge memory and automatically purged, guaranteeing that author intellectual property is never exposed to self-plagiarism flags or harvested for AI training.

## Core Capabilities & Technical Architecture
- **Multi-Source Scholarly Retrieval**: Real-time distributed querying across 250M+ scholarly publications via international open-access academic registries, peer-reviewed journal indexes, doctoral dissertation archives, and authoritative scholarly web literature.
- **Total Similarity Index (TSI)**: Comprehensive composite scoring measuring exact verbatim string matches, n-gram shingle overlap, and semantic near-matches with direct DOI and author attribution.
- **Stylometric AI & Burstiness Detection**: Multi-signal syntactic variance, perplexity, and lexical entropy analysis identifying machine-generated prose and synthetic AI generation patterns with sentence-by-sentence highlight heatmaps.
- **Mathematical Formula & Equation Matching**: Structural comparison of mathematical equations across LaTeX and symbol patterns.
- **Multi-Format Text Extraction**: High-fidelity text extraction supporting native digital PDF, DOCX, TXT, and LaTeX documents up to 25,000 words per scan.
- **Zero-Vault Ephemeral Architecture**: Zero persistent manuscript storage. Screening evidence is temporarily cached for 24 hours solely for the author to review and export their official report, after which all document text is permanently purged. Authors can trigger instant cloud erasure at any time.
- **Official Downloadable PDF Reports**: Branded single-page summary PDF reports bearing a unique Report ID, TSI similarity percentage, AI content probability, and audit timestamp.

## Pricing & Product Tiers
- **Student Plan (₹99 INR)**: Single-use comprehensive forensic screening voucher with full plagiarism and AI detection, sentence-level highlights, and downloadable official PDF report.
- **Author Pack (₹499 INR)**: 6 independent screening vouchers designed for thesis revisions, multi-chapter dissertations, and journal submissions.
- **Campus Pro (₹49,000 INR)**: Annual institutional campus license providing 10 screens per day (3,650 screens/year) with an Institutional Master Key, priority compute, and full editorial audit features.

## Regulatory Compliance & Ethics
- **DPDP Act 2023 Compliant**: Adheres to India's Digital Personal Data Protection Act 2023 with author data sovereignty, instant user purge, and statutory Grievance Redressal Officer support.
- **Academic Standards**: Designed for pre-submission author draft review. Provides independent, consultative similarity (TSI) and reference retraction screening to uphold scholarly integrity without claiming third-party regulatory certification.
- **Payment Security**: Transactions processed via Razorpay with PCI-DSS Level 1 compliance and 256-bit TLS encryption.
