Ksh850.00
GPTZero is a leading artificial intelligence detection platform founded in early 2023 by Edward Tian at Princeton University. It is primarily designed to identify whether text was written by a human or generated by large language models (LLMs) like ChatGPT, GPT-4, and Claude.
Core Capabilities
AI Detection: Uses metrics like perplexity (text randomness) and burstiness (variation in sentence structure) to distinguish AI patterns from human writing.
Classification Levels: Categorizes text into three types: Human-only, AI-only, or Mixed (a combination of both).
Plagiarism & Integrity Tools: Includes a built-in plagiarism checker and a "Source Finder" that scans over 220 million scholarly articles and news sources to verify claims and provide citations.
Origin Chrome Extension: A unique tool for Google Docs that allows users to "replay" their writing process, serving as proof of authenticity to avoid false accusations of cheating.
