AI content detectors are tools that check text for AI presence. How do AI detectors determine whether AI or humans created the content? 

There are two main types of AI content detectors: rule-based and machine learning-based.

Rule-based AI content detectors

Rule-based AI content detectors use specific rules or heuristics to identify AI-generated content. In particular, they can look for repeating patterns, inconsistencies, a specific selection of vocabulary, grammatical features, and other features typical of AI-generated text. R-based AI detectors are lightweight and fast but cannot always catch complex content. They can give false positives or negatives if the rules are too strict or lenient.

AI content detectors based on machine learning

AI content detectors based on machine learning use data-driven algorithms among their methods: natural language processing, deep learning, or statistical analysis to analyze the features and characteristics of different types of content. ML-based AI detectors are more flexible than rule-based detectors because they can learn new data and improve their accuracy over time. However, training and running may require more computing resources and data. They may also be less precise than rule-based ones.

Conclusion

Rule-based AI content detectors use predefined rules or heuristics to identify AI-generated content, while machine learning-based AI content detectors use data-driven algorithms. Both types have advantages and disadvantages and can be used for different purposes, scenarios, or combined.
