GPTZero

GPTZero, developed by Princeton University students, is an AI content detection tool that identifies and analyzes input text to determine whether it was created by AI, distinguishing between human-generated and AI-generated content. The tool supports AI content detection at the sentence, paragraph, and document levels, judging text origin by analyzing its “perplexity” (i.e., the complexity and unpredictability of the text) and “explosiveness” (i.e., the degree of variation in sentence structure and length). Human writing is more complex and varied, while AI-generated text is relatively regular and uniform. GPTZero is applied in education, publishing, and content moderation to help users identify AI-generated content and maintain academic integrity and information authenticity.

GPTZero’s main functions

• AI text detection : By analyzing the “perplexity” and “burstiness” of text, it determines whether the text was written by a human or generated by AI.
• Sentence-level and paragraph-level analysis : Provides detection results for the entire document, and can analyze sentence by sentence or paragraph by paragraph to indicate which parts may have been generated by AI.
• Multi-model support : Supports detection of text generated by various mainstream AI models, including ChatGPT, GPT-3, GPT-4, Google Gemini, etc.
• Batch Detection and API Interface : Supports batch uploading of documents for detection, and provides an API interface for easy integration by educational institutions, publishers or content platforms.
• Education-specific features : Provides a dedicated detection platform for teachers and educational institutions to help identify whether AI-generated content exists in student assignments, thus maintaining academic integrity.
• Browser Extensions and Plugins : Provides Chrome browser extensions and Microsoft Word plugins to help users detect text sources in real time during daily writing or reviewing.
• Writing Feedback and Originality Report : In addition to the detection function, writing feedback and originality reports are provided to help users improve their writing quality.
• Supports multiple text formats : You can directly input text online, or upload files in formats such as .pdf, .doc, .docs, and .txt for testing.
• Batch file scanning : Supports uploading multiple files at once for AI content detection, saving time spent on repeated uploads.

How to use GPTZero

• Visit the official website and register an account : Visit the GPTZero official website (https://gptzero.me), register and log in to your account.
• Upload or paste text : After logging in, you can directly copy and paste the text you want to detect into the detection box on the webpage, or you can upload PDF, Word, or plain text files.
• Click the “Detect” button : After uploading or pasting the text, click the “Scan” or “Detect” button, and the system will automatically analyze the text content.
• View the detection results : GPTZero will provide the detection results, including an overall assessment (AI-generated or human-written) and a detailed sentence-level analysis, highlighting parts that may have been generated by AI.
• Use advanced features (optional) : As needed, you can choose to use advanced features such as AI vocabulary analysis, plagiarism check, writing feedback, etc., to get more detailed reports.
