ChatGPT, Claude and Bard, etc. AI Content generators are trained on massive datasets of text and code. They can mimic human writing styles, generate creative text formats, translate languages, and write creative content. AI detector tools, on the other hand, are designed to help determine how to tell if something was written by AI. They check the text for specific patterns and properties that indicate AI authorship, such as low variance in sentence length and word choice.
As AI technology continues to advance, AI detector software is likely to become more sophisticated and accurate. In the future, AI detector software may be able to identify not only AI-generated content, but also the specific type of AI used to generate the content.
