An AI detector is a tool designed to identify whether a piece of text was written by a human or an artificial intelligence (AI) solution. These detectors play a crucial role in verifying content authenticity and distinguishing between human-generated and AI-generated text.
How Do AI Detectors Work?
- AI detectors use language models similar to those used in AI writing tools.
- They assess perplexity (text predictability) and burstiness (variance in sentence structure and length).
- Perplexity: AI-generated text tends to have low perplexity (more predictable), while human writing has higher perplexity (more creative but with typos).
- Burstiness: AI-generated text exhibits less burstiness (consistent sentence length and structure), whereas human writing varies more.
- These detectors help educators verify student work, marketers ensure original content, and moderators combat spam23.
They scrutinize text patterns to distinguish between human and AI-generated content, aiding in maintaining authenticity and integrity in various contexts.
