Plagiarism and AI Detection for High Schools
Equip high school educators with clear plagiarism detection, sentence-level AI signals, writing process playback, and automated rubric grading built for secondary classrooms.
High-School Writing Challenges
Secondary teachers face complex academic integrity hurdles in the era of generative AI.
Essays Written with Generative AI
High school students frequently turn to ChatGPT, Claude, or AI rewriters to generate complete essays, leading to unearned grades and missed learning.
Improper Paraphrasing & Citation
Students often rearrange source words without proper attribution or clear quotation marks, leading to accidental plagiarism in research papers.
Students Copying Classmates
Shared documents and messaging apps make it easy for students in different class periods to share homework answers and essay paragraphs.
Difficulty Establishing Authorship
When an essay looks polished, teachers lack objective evidence to determine whether the student wrote it themselves or generated it.

Combine web source matches, paste timestamps, and revision playback to see the complete picture.
Give department chairs and teachers a standardized checklist for fair, repeatable investigations.

“The edit playback feature resolved three separate AI flag disputes in my AP Literature class this semester. Students who actually wrote their papers could easily prove their work, while those who used AI were caught without guesswork.”
