GPTZero — AI for Education & E-learning

When you need to assess the originality of a piece of writing, GPTZero provides a data-driven starting point. You can paste text, upload files, or use a browser extension to scan content. The tool works by analyzing text for patterns characteristic of AI generation, such as low 'perplexity' (predictable word choices) and consistent sentence structure. It then returns an overall percentage score indicating the probability that the entire text is AI-generated. More importantly, its 'deep scan' feature highlights individual sentences, color-coding them based on their likelihood of being written by an AI. This allows for a more nuanced review than a single score. You can use this to identify specific areas that warrant closer inspection. However, it is critical to understand that this is a statistical analysis, not a definitive judgment. These tools are known to sometimes flag human writing, especially from non-native English speakers, as AI-generated. Therefore, you should use the results as one piece of evidence in a larger review process, never as the sole basis for an accusation.
