## Frequently asked questions

### What is an AI content detector?

An AI content detector is a software built to provide clarity on the originality of a text, and determine whether a given text was written by an AI text generation tool such as ChatGPT or if it was written by a human. AI content detections use large datasets and a number of other factors to provide this assessment.

### How do AI detectors work?

AI content detection utilizes natural language processing, machine learning, and deep learning to analyze text and determine whether it was written by a human or an AI. The AI learns the nuances of human language, identifies patterns that differentiate human and AI writing, makes predictions about new text, assigns a score indicating the likelihood of human or AI authorship, and continuously improves through updated training data.

### What's the difference between Plagiarism Checkers and AI Writing Detectors?

Plagiarism detection refers to the process of identifying instances of plagiarism, which is the act of using someone else’s work or ideas without giving them proper credit. This can include text, images, or other forms of media.

AI detection, on the other hand, refers to the use of artificial intelligence tools such as ChatGPT to generate copy.

### Can teachers detect if you used an AI assistant like ChatGPT for schoolwork?

Teachers have ways to detect AI involvement in student assignments. They may notice unnatural language, lack of depth, inconsistency, or use AI detection software. Students should avoid relying on AI for their work since it could be seen as academic dishonesty.

### Are AI detection tools accurate?

AI detectors have been developed to determine if online content is human or machine-generated, though their effectiveness currently varies. Winston AI has by far the best percentage rate (99,98%) of detecting AI generated content from ChatGPT, GPT-4, Bard, and other popular text generation tools.

As the technology improves, AI content detectors are expected to become more accurate and help ensure the authenticity of online information.

### Does Google detect AI content?

AI text generators have raised concerns about the impact of AI-generated content on SEO (search engine optimization). While AI-generated content threatens to produce low-quality spam, search engines like Google are improving algorithms to detect such content.

### What does Winston do exactly?

Winston is the leading AI generated text detection tool. Our software is able to detect AI generated copy with a 99,98% accuracy including content generated by ChatGPT. Our software also includes a best in class plagiarism detection tool.

### Which languages does Winston AI work with?

We currently only support AI detection for English, French, Spanish, Portuguese, German, Dutch, Polish, Italian, Indonesian, Romanian and Chinese (Simplified) content. Detection for more languages is coming soon.
