The functioning of text generation AI involves making educated guesses about the next word based on contextual information. AI detection tools employ a reverse engineering approach by generating a word and observing whether the subsequent word aligns with the expected prediction. An example illustrating this concept is shown in the accompanying image.

When the AI detection tool detects a consistent pattern like this, it indicates that the content is likely generated by AI. It assigns a score usually ranging from 1 to 100% by calculating the discrepancy between the predicted next word and the actual word, determining how closely they match.
