Description
The AI Humanizer and Detector by Rephrasy is a Chrome browser extension designed to combat the challenges of AI-generated content. It provides two primary functionalities: AI detection and AI text humanization. With the AI Detector, users can accurately identify content written by artificial intelligence, supporting the verification of human authorship.
The extension boasts over 90% accuracy and a low false positive rate, capable of detecting text from popular AI models like ChatGPT, Gemini, and Claude. It is engineered to identify AI text even if it has been paraphrased by other AI tools or mixed with human-written content, ensuring robust detection capabilities.
Complementing its detection features, the Humanization feature transforms AI-generated text to sound more natural and human-like. This process aims to make AI-written content indistinguishable from human writing, effectively bypassing AI detectors. The goal is to ensure that the authenticity of written content is maintained, regardless of its origin.
Using the Rephrasy.ai extension is straightforward. After downloading and activating it, users need to input an API key obtained from Rephrasy.ai into the extension's settings. Once configured, users can right-click on any website and select "Rephrasy: Analyze selected text" to utilize the AI detection or humanization tools.
The developer, Rephrasy.ai, has a good record with no history of violations. The extension is available in English and has been updated to version 1.0.4 as of January 30, 2025. The developer states that they will not collect or use user data, and it is not sold to third parties outside of the item's core functionality.
