GPTZero

What is GPTZero?

GPTZero is an AI detection platform that checks whether text came from a person or a language model. It scores documents sentence by sentence, flags mixed writing, and adds plagiarism checks, hallucination spotting, and a writing replay showing how a draft was produced. Integrations reach Chrome, Canvas, and Google Classroom.

Top Features:

• Sentence level highlighting: the report marks exactly which lines look machine generated.
• Writing replay: playback shows how a document was typed, pasted, or edited.
• Plagiarism and hallucination checks: copied passages and invented facts surface in one scan.

Use Cases:

• Classroom review: teachers check submissions before grading essays and take-home assignments.
• Hiring screens: recruiters verify that cover letters reflect the candidate's writing.
• Editorial checks: publishers screen freelance submissions before paying for and printing.
