Checkmark Plagiarism seamlessly integrates with your Google Classroom™ workflow, providing educators with a powerful tool for auto-grading and plagiarism detection. Designed by teachers, this add-on analyzes not just what students wrote, but how they wrote it—using Google Docs™ revision history and keystroke behavior. When a teacher attaches Checkmark Plagiarism to an assignment, students submit their Google Docs™ as usual. The system automatically processes these submissions, generating both plagiarism reports and AI-assisted grading feedback. Teachers can view submission statuses directly within the add-on, while students receive their own reports inside Google Classroom™, receiving immediate feedback. Key Features of Checkmark Plagiarism: • Auto-Grading – AI-assisted scoring helps save time while preserving teacher oversight • Keystroke-Based Plagiarism Detection – Analyzes the writing process via revision history and typing behavior • Document Playback – Replay how the essay was written, not just what was written • Traditional plagiarism detection Checkmark Plagiarism simplifies grading and elevates academic integrity, empowering teachers to focus on what matters most: helping students grow as original thinkers and writers.
